FEDERICO, Circuit Judge. _________________________________

Petitioner Rigoberto Santillan Quiroz has been detained for more

than eight consecutive months and counting. He is not charged with a

crime. Nor does anyone suggest that he is a flight risk or a danger to the

community. Rather, he is in pre-adjudicative detention 1 awaiting the

outcome of his pending immigration removal proceedings. And because the

Government recently interpreted immigration law to mandate his

detention, Santillan Quiroz has not had the chance to argue for release at a

bond hearing.

1 The term “pre-adjudicative detention” is not often used to label the circumstances of immigration detainees pending removal proceedings even though it is perhaps most descriptively accurate. See, e.g., Lindsay Nash, Resurrecting Immigration Releases, 135 Yale L.J. 1533, 1547 (2026) (discussing author’s preference for “pre-adjudication detention”); Kim v. Ziglar, 276 F.3d 523, 533 (9th Cir. 2002) (also using “pre-adjudication civil detention”), rev’d sub-nom., Demore v. Kim, 538 U.S. 510 (2003). For simplicity, we will refer to Santillan Quiroz’s status and circumstances as detention.

3 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 4

His case is before this court on appeal from the denial of a petition for

a writ of habeas corpus challenging his detention. Santillan Quiroz asks us

to order the Government to release him or, alternatively, to provide him

with a bond hearing to determine his suitability for release. The

Government contests his petition, arguing that he is subject to mandatory

detention and thus not entitled to release or a bond hearing.

The question before us is whether Santillan Quiroz is eligible for bond

and therefore entitled to meaningfully challenge his detention at a bond

hearing before an immigration judge. Answering this question will require

the court to navigate several statutory provisions found in our Nation’s

immigration laws.

We are not the first circuit court of appeals this year to wrestle with

this issue. That is because the Government did not take the position – that

petitioners like Santillan Quiroz are ineligible for release and thus not

entitled to a bond hearing – until July 2025, so its position stems from a

new and novel reading of old statutes. The Government’s new position has

resulted in a large increase in the number of immigration detainees and a

flood of habeas petitions challenging those detentions. The circuits have

split on the best reading of the applicable statutes, and we are the latest

court of appeals to weigh in on this question of national importance.

Although the petition at issue presents a question of statutory

4 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 5

interpretation with nationwide implications, a habeas corpus petition is

inherently personal. It is a challenge by one man, Santillan Quiroz, who

remains detained by Immigration and Customs Enforcement (ICE).

The district court determined that Santillan Quiroz is not eligible for

release or entitled to a bond hearing. We disagree and reverse.

I

Two decades ago, in 2006, Santillan Quiroz entered the United States.

He has lived here ever since.

In that time, Santillan Quiroz started a family. He married a lawful

permanent resident and became a father to a U.S.-citizen stepdaughter. He

provided for them financially and stayed by his wife’s side to offer care and

support as she underwent treatment for a heart condition. Apart from one

DUI for which he completed community service, he has no criminal history.

By all accounts, Santillan Quiroz has become a valued and contributing

member of his community.

On November 2, 2025, ICE agents whisked Santillan Quiroz away

from his family. After detaining Santillan Quiroz at a traffic stop, the

agents initiated removal proceedings against him on the basis that he

entered the country without admission or parole. But they did not release

Santillan Quiroz after the traffic stop concluded. Instead, they held him for

several more days before eventually sending him to a detention center,

5 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 6

where he remains in custody to this day. According to the Government,

Santillan Quiroz must remain in mandatory detention pursuant to 8 U.S.C.

§ 1225(b)(2)(A). Pointing to the same provision, the Government also claims

that Santillan Quiroz is not entitled to a bond hearing and, as such, has not

provided him with the opportunity to argue for release.

Santillan Quiroz filed a petition for a writ of habeas corpus pursuant

to 28 U.S.C. § 2241. He asserted in his petition that the Government

wrongly invoked § 1225(b)(2)(A) to detain him. Rather, Santillan Quiroz

argued, his detention can only be authorized under 8 U.S.C. § 1226(a), and

he is eligible for a bond hearing under that provision. A magistrate judge

recommended granting Santillan Quiroz’s petition. However, the district

court rejected that recommendation and denied the petition. Santillan

Quiroz timely appeals that denial.

II

The Immigration and Nationality Act (INA) is “[t]he foundation of our

laws on immigration and naturalization.” Kansas v. Garcia, 589 U.S. 191,

195 (2020). Thirty years ago, Congress amended the INA when it enacted

the Illegal Immigration Reform and Immigrant Responsibility Act of 1996

(IIRIRA), Pub. L. No. 104-208, 110 Stat. 3009-546.

IIRIRA reformed the immigration removal system. Pre-IIRIRA,

removal turned on physical entry. Kawashima v. Holder, 565 U.S. 478, 481

6 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 7

n.2 (2012). Noncitizens 2 who had been stopped at the border or ports of

entry (border, for short) were placed in exclusion proceedings and

removable on grounds of excludability. Id. Noncitizens who had entered the

country, whether lawfully or not, were placed in deportation proceedings

and removable on grounds of deportability. Id.

Post-IIRIRA, distinctions based on lawful entry replaced those based

on physical entry. Specifically, IIRIRA introduced the term “admission,”

which it defined as “the lawful entry of the alien into the United States after

inspection and authorization.” 8 U.S.C. § 1101(a)(13)(A). Noncitizens who

had entered the country unlawfully and therefore had not been admitted

were subject to removal on grounds of inadmissibility. Judulang v. Holder,

565 U.S. 42, 46 (2011) (citing 8 U.S.C. § 1182(a)). Noncitizens who had

entered lawfully and had been admitted remained subject to removal on

grounds of deportability. See 8 U.S.C. § 1227(a). Finally, IIRIRA merged

exclusion proceedings and deportation proceedings into a single set of

removal proceedings. Kawashima, 565 U.S. at 481 n.2.

2 The INA uses the word “alien,” defined as “any person not a citizen

or a national of the United States,” instead of “noncitizen.” 8 U.S.C. § 1101(a)(3). This opinion uses the term “noncitizen” to describe Santillan Quiroz and as an equivalent to “alien,” unless “alien” appears within a quotation or is used as part of a statutory term of art.

7 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 8

In conjunction with these reforms, IIRIRA consolidated the

Government’s authority to detain noncitizens with pending removal

proceedings into two provisions: § 1225 and § 1226. Of these two, § 1225

makes no mention of bond and instead mandates that noncitizens subject

to its authority “shall be detained.” 8 U.S.C. §§ 1225(b)(1)(B)(ii),

(b)(1)(B)(iii)(IV), (b)(2)(A). Meanwhile, § 1226 permits immigration officials

to “release the alien on . . . bond” subject to some exceptions. 8 U.S.C.

§ 1226(a)(2)(A).

Soon after IIRIRA became law, the Government promulgated a

regulation interpreting the relationship between § 1225 and § 1226. The

regulation explained that “arriving aliens” (i.e., those at the border) are

subject to § 1225 and do not “have available to them bond redetermination

hearings.” 62 Fed. Reg. 10312, 10323 (Mar. 6, 1997). By contrast, “aliens

who are present without having been admitted or paroled [i.e., those already

inside the United States] will be eligible for bond” under § 1226. Id. In

simpler terms, the regulation said that § 1225 generally applies at the

border while § 1226 applies in the country’s interior.

Over the course of the next five Presidential administrations, that

understanding held. But in July 2025, the Government reversed course. For

the first time in IIRIRA’s nearly thirty-year history, the Government took

the position that § 1225, specifically subsection (b)(2)(A), applied to

8 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 9

noncitizens who had already entered the country without admission.

Memorandum from Rodney S. Scott, Commissioner, U.S. Customs & Border

Protection (July 10, 2025), https://perma.cc/C6SM-MXGS. Two months

later, the Board of Immigration Appeals followed suit and agreed with the

Government’s new reading of the statute. Matter of Yajure Hurtado, 29 I. &

N. Dec. 216 (B.I.A. 2025).

These twin decisions – made within the executive branch – led to a

wave of habeas petitions challenging the mandatory detention of

unadmitted noncitizens based on the Government’s newly minted

interpretation. In the past few months, those petitions have begun to work

their way into the circuit courts. So far, the Second, Sixth, and Eleventh

Circuits have each held that § 1225(b)(2)(A) does not apply to unadmitted

noncitizens who, like Santillan Quiroz, are found in the country’s interior.

Barbosa da Cunha v. Freden, 175 F.4th 61 (2d Cir. 2026); Lopez-Campos v.

Raycraft, 175 F.4th 713 (6th Cir. 2026); Hernandez Alvarez v. Warden, Fed.

Det. Ctr. Mia., 175 F.4th 1258 (11th Cir. 2026). The Fifth and Eighth

Circuits have agreed with the Government that § 1225(b)(2)(A) applies.

Buenrostro-Mendez v. Bondi, 166 F.4th 494 (5th Cir. 2026); Avila v. Bondi,

170 F.4th 1128 (8th Cir. 2026).

Every other numbered circuit has heard argument on the question.

Guerrero Orrellana v. Moniz, Nos. 25-2152, 26-1094 (1st Cir.) (argued

9 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 10

May 4, 2026); Buele Morocho v. Warden Phila. FDC, Nos. 26-1150, 26-1454

(3d Cir.) (argued May 11, 2026); Lopez Garcia v. Guadian, Nos. 25-7044,

25-7050 (4th Cir.) (argued May 5, 2026); Cirrus Rojas v. Olson, No. 25-3127

(7th Cir.) (argued June 15, 2026); 3 Rodriguez Vazquez v. Bostock,

No. 25-6842 (9th Cir.) (argued March 4, 2026). This court now adds its voice

to the conversation on this important question of statutory interpretation.

III

We have jurisdiction over Santillan Quiroz’s appeal under 28 U.S.C.

§ 1291. Because he appeals from the denial of a § 2241 habeas petition, “we

review legal questions de novo and factual findings for clear error.”

Standifer v. Ledezma, 653 F.3d 1276, 1278 (10th Cir. 2011). The sole issue

we address in this appeal is whether § 1225(b)(2)(A) or § 1226(a) applies to

Santillan Quiroz – a purely legal question of statutory interpretation – so

our review is de novo. Daley v. Ceja, 158 F.4th 1152, 1156 (10th Cir. 2025).

A

The court’s task when interpreting a statute is to “give effect to the

clear meaning of [that] statute[] as written.” Star Athletica, LLC v. Varsity

3 A prior Seventh Circuit panel previously deadlocked on this issue in

the context of an appeal from the refusal to dissolve an immigration consent decree. Castañon-Nava v. U.S. Dep’t of Homeland Sec., 175 F.4th 828 (7th Cir. 2026).

10 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 11

Brands, Inc., 580 U.S. 405, 414 (2017) (quoting Est. of Cowart v. Nicklos

Drilling Co., 505 U.S. 469, 476 (1992)). Courts do so “by reference to the

language itself, the specific context in which that language is used, and the

broader context of the statute as a whole.” Robinson v. Shell Oil Co.,

519 U.S. 337, 341 (1997). Often, this requires courts to dive into textual

minutiae, parsing verb tense and the choice of one synonym over another.

We will soon be doing just that. But before we get there, we first step back

to appreciate the “broader context of the statute” and the baseline upon

which we perform our statutory analysis.

A statute’s broader context includes “the longstanding practice of the

government.” Loper Bright Enters. v. Raimondo, 603 U.S. 369, 386 (2024)

(internal quotation marks and citation omitted). Here, the Government’s

interpretation of nearly thirty years – that § 1225(b)(2)(A) applies at the

border while § 1226(a) applies in the interior – qualifies as such a

longstanding practice. See 62 Fed. Reg. at 10323. “[T]he fact that no

President has ever found” § 1225(b)(2)(A) to mandate detention in the

interior until now is “strong evidence that [such mandate] does not exist.” 4

4 Citing 8 C.F.R. § 235.3(b)(1)(ii), the Fifth Circuit reasoned that the

Government had previously extended § 1225(b)(2)(A) beyond the border. Buenrostro-Mendez, 166 F.4th at 507; accord Hernandez Alvarez, 175 F.4th at 1307 (Lagoa, J., dissenting). Not quite. Although this regulation references § 1225(b)(2)(A), it implements expedited removal under a

11 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 12

Learning Res., Inc. v. Trump, 607 U.S. 229, 250 (2026). Indeed, the Supreme

Court has previously invoked this principle in the immigration context,

rejecting an interpretation of a statutory subsection at odds with one that

“every Presidential administration” had adopted in the then-26 years

“[s]ince IIRIRA’s enactment.” Biden v. Texas, 597 U.S. 785, 805 (2022).

Resisting this idea, the Government suggested at oral argument that

this history is merely unreasoned practice (as opposed to reasoned executive

analysis) that grew out of “bureaucratic inertia.” Oral Arg. at 39:00–39:45.

Maybe so. But that characterization gives the Government no aid because

it is precisely “Presidential practice” that matters. Learning Res., 607 U.S.

at 250 (emphasis added). So long as the executive branch issued an

“interpretation . . . roughly contemporaneously with enactment of the

statute” (check), and that interpretation “remained consistent over time”

(check), we give the Government’s longstanding interpretation weight in

the analysis. Loper Bright, 603 U.S. at 386. The fact that this interpretation

came in the form of an affirmative regulatory action, 62 Fed. Reg. at 10323,

also refutes the Government’s related argument that we are dealing with a

different subsection, § 1225(b)(1). So far as it extended detention into the interior, it did so only for noncitizens who satisfied the criteria in § 1225(b)(1)(A)(iii)(II), a subsection that does not apply to § 1225(b)(2)(A).

12 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 13

mere “lack of administrative exercise.” See Resp. Br. at 52–53 (citing

Bankamerica Corp. v. United States, 462 U.S. 122, 131 (1983)).

What’s more, the Supreme Court has endorsed this (until recently)

unbroken interpretation and practice. In Jennings v. Rodriguez, the

Supreme Court explained that, for purposes of our immigration laws, § 1225

governs the processing of noncitizens at “the Nation’s borders and ports of

entry.” 583 U.S. 281, 287 (2018). Once noncitizens are “inside the United

States,” § 1226 “generally governs the process of arresting and detaining

that group of aliens pending their removal.” Id. at 288. In short, Jennings

explained that § 1225 “authorizes the Government to detain certain aliens

seeking admission into the country” while § 1226 “authorizes the

Government to detain certain aliens already in the country.” Id. at 289

(emphasis added). 5 We therefore approach the Government’s novel,

contrary position with a healthy dose of skepticism.

5 Jennings’s description of the interplay between § 1225 and § 1226 is

obiter dictum. Still, we are “bound by Supreme Court dicta almost as firmly as by the Court’s outright holdings, particularly when the dicta is recent and not enfeebled by later statements.” N. Mill St., LLC v. City of Aspen, 6 F.4th 1216, 1228 n.11 (10th Cir. 2021) (quoting United States v. Serawop, 505 F.3d 1112, 1122 (10th Cir. 2007)). Jennings therefore counsels, if not requires, us to rule in Santillan Quiroz’s favor since immigration agents did not arrest Santillan Quiroz at the border. The Government objects that Jennings is ambiguous on whether § 1225 is restricted to the border. But we need not linger on the meaning of Jennings’s dicta. In light of the importance of the issues raised in this appeal, we conduct a full statutory

13 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 14

With that baseline established, we proceed with a statutory analysis.

We first analyze the text of the specific provision invoked to detain Santillan

Quiroz, § 1225(b)(2)(A), including how that provision fits into § 1225 as a

whole. We then discuss how § 1225(b)(2)(A) interacts with § 1226(a) before

considering and rejecting the Government’s statutory purpose arguments.

Finally, we explain how and why constitutional avoidance applies here. We

hold that noncitizens who entered the United States and were thereafter

detained in the interior of the country are usually subject to § 1226(a) (and

thus eligible for bond), not § 1225(b)(2)(A). 6

B

“We begin, as always, with the language of the statute.” Duncan v.

Walker, 533 U.S. 167, 172 (2001). Here, that language reads in relevant

part:

[I]n the case of an alien who is an applicant for admission, if the examining immigration officer determines that an alien seeking admission is not clearly and beyond a doubt entitled to be admitted, the alien shall be detained for a [removal] proceeding[.]

8 U.S.C. § 1225(b)(2)(A) (emphases added).

analysis as if Jennings’s dicta were nonbinding, and we ultimately reach the same result. 6 Some noncitizens who are arrested in the interior may be subject to

§ 1225(b)(1)(A). There is no argument here that § 1225(b)(1)(A) applies to Santillan Quiroz.

14 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 15

The outcome of this appeal turns on how § 1225(b)(2)(A) uses the

terms “applicant for admission” and “seeking admission.” According to

Santillan Quiroz, each of the two terms are independent restrictions on

§ 1225(b)(2)(A)’s scope. He concedes that he is an applicant for admission

but contends that he is not seeking admission. So, from his perspective,

§ 1225(b)(2)(A) does not apply to him or noncitizens like him. On the other

hand, the Government argues that “seeking admission” has no independent

force separate from “applicant for admission.” From its vantage point,

§ 1225(b)(2)(A) applies to all applicants for admission, including Santillan

Quiroz and other unadmitted noncitizens arrested in the country’s interior.

Two mirror image principles guide our interpretation of “applicant for

admission” and “seeking admission.” First, “[w]hen a term goes undefined

in a statute, we give the term its ordinary meaning.” Taniguchi v. Kan Pac.

Saipan, Ltd., 566 U.S. 560, 566 (2012). Second, “[w]hen ‘a statute includes

an explicit definition’ of a term, ‘we must follow that definition[] even if it

varies from a term’s ordinary meaning.’” Van Buren v. United States,

593 U.S. 374, 387 (2021) (quoting Tanzin v. Tanvir, 592 U.S. 43, 47 (2020));

accord Feliciano v. Dep’t of Transp., 605 U.S. 38, 50 n.4 (2025).

“Applicant for admission” is a defined term. Accordingly, we eschew

its ordinary meaning in favor of its statutory definition: “An alien present

15 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 16

in the United States who has not been admitted or who arrives in the United

States[.]” 8 U.S.C. § 1225(a)(1).

By contrast, “seeking admission” is only partially defined. Congress

defined “admission” to mean lawful entry following inspection, but it said

nothing about what it means to be “seeking” something. 8 U.S.C.

§ 1101(a)(13)(A). This tells us “seeking admission” is equivalent to “seeking

lawful entry” and leaves us to define “seeking” according to that word’s

ordinary meaning.

To determine the ordinary meaning of “seek,” we consult

contemporary dictionaries. See M.S. v. Premera Blue Cross, 118 F.4th 1248,

1266 (10th Cir. 2024). Here, our sister circuits have already done the

legwork by canvassing such dictionaries, and we agree with them that

“seek” ordinarily means “request,” “ask for,” or something similar. Barbosa

da Cunha, 175 F.4th at 74; accord Lopez-Campos, 175 F.4th at 722–23;

Avila, 170 F.4th at 1134; Buenrostro-Mendez, 166 F.4th at 502. Of course,

§ 1225(b)(2)(A) does not use the verb “seek” but rather the present participle

“seeking.” The choice of present participle adds another layer to our

interpretation because it requires present and continuing action. See, e.g.,

D.L. Markham DDS, MSD, Inc. 401(K) Plan v. Variable Annuity Life Ins.

Co., 88 F.4th 602, 610 (5th Cir. 2023); United States v. Stewart, 73 F.4th

423, 425 (6th Cir. 2023); Westchester Gen. Hosp., Inc. v. Evanston Ins. Co.,

16 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 17

48 F.4th 1298, 1307 (11th Cir. 2022); Shell v. Burlington N. Santa Fe Ry.

Co., 941 F.3d 331, 336 (7th Cir. 2019).

Putting these pieces together, we conclude that a noncitizen is

“seeking admission” when he takes some kind of ongoing action to request

lawful entry into the United States. To be clear, we do not construe “seeking

admission” as limited to the literal moments that a noncitizen is filling out

a form or speaking with an immigration official to request admission. See

Buenrostro-Mendez, 166 F.4th at 502; Avila, 170 F.4th at 1134. It is enough

that some pending request for admission remains open or ongoing because

that indicates the process of securing admission is still active. See Khakhn

v. Holder, 371 F. App’x 933, 937 (10th Cir. 2010) 7 (suggesting that under

our immigration laws, a person is “‘applying’ for adjustment of status” until

“his application [is] denied”).

With these constructions of “applicant for admission” and “seeking

admission” in hand, it becomes apparent why § 1225(b)(2)(A) does not apply

to Santillan Quiroz. By statutory definition, Santillan Quiroz is an

applicant for admission because he is present in the United States without

7 We cite unpublished decisions for their persuasive value only and do

not treat them as binding precedent. 10th Cir. R. 32.1(A).

17 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 18

having been admitted. See 8 U.S.C. § 1225(a)(1). However, he is not seeking

admission since he has no present request for lawful entry pending.

The fact that Santillan Quiroz is not seeking admission is more than

mere happenstance. Noncitizens in Santillan Quiroz’s position – that is,

those who entered the United States without admission and who have lived

here since – are categorically unable to seek admission while they remain

in the country. Part of the reason is a matter of logic and common sense. A

person cannot make a present request for permission to enter the United

States, lawfully or otherwise, once he or she has already entered.

The other reason this is true relates to the structure of our

immigration laws. A noncitizen can request legal status even after he has

entered the United States unlawfully, but he cannot request admission

after the fact. That is because “[l]awful status and admission . . . are distinct

concepts in immigration law.” Sanchez v. Mayorkas, 593 U.S. 409, 415

(2021). Lawful status allows a noncitizen “to remain in the country.” Id.

at 416. Admission, though, is defined in terms of “entry into the United

States, denoting by its plain terms passage into the country from abroad.”

Medina-Rosales v. Holder, 778 F.3d 1140, 1145 (10th Cir. 2015) (emphasis

in original) (quoting Negrete-Ramirez v. Holder, 741 F.3d 1047, 1051

(9th Cir. 2014)). The concept of admission “does not encompass a post-entry

adjustment of status” because such adjustment does not involve “passage

18 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 19

into the country from abroad.” Id. (emphasis added) (citation omitted);

accord Martinez v. Mukasey, 519 F.3d 532, 544 (5th Cir. 2008). So, for

instance, a noncitizen who entered the country unlawfully, but who later

receives temporary protected status or asylum, does not become admitted

even though he has lawful status. Sanchez, 593 U.S. at 415.

The upshot is that once a noncitizen has entered unlawfully, no

amount of legal maneuvering allows him to go back in time and make his

initial entry lawful. The only time a noncitizen can be said to be seeking

admission is when he is seeking to enter the United States at the border. 8

Since § 1225(b)(2)(A) applies only to those seeking admission,

§ 1225(b)(2)(A) is likewise limited to the border.

This border-oriented result tracks with the larger context of § 1225,

starting with the section’s title: “Inspection by immigration officers;

expedited removal of inadmissible arriving aliens; referral for hearing.”

8 Our dissenting colleague on the Sixth Circuit observes that “the law

sometimes treats present immigrants as ‘seeking admission’ even after an illegal entry.” Lopez-Campos, 175 F.4th at 752 (Murphy, J., dissenting). That’s true as far as it goes. Under 8 U.S.C. § 1101(a)(13)(C), some lawful permanent residents are regarded as seeking admission even after entering the country. But § 1101(a)(13)(C) is a specific statutory carveout that applies only to lawful permanent residents. It does not apply to noncitizens like Santillan Quiroz who never had lawful permanent resident status and therefore does not displace the ordinary meaning of “seeking admission” as applied to Santillan Quiroz.

19 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 20

8 U.S.C. § 1225. While a title does not control over the text, it can helpfully

“reinforce[] what the text’s nouns and verbs independently suggest.” Dubin

v. United States, 599 U.S. 110, 120–21 (2023) (quoting Yates v. United

States, 574 U.S. 528, 552 (2015) (Alito, J., concurring in the judgment)).

Such is the case here.

For starters, § 1225’s title refers to “[i]nspection by immigration

officers.” When Congress enacted IIRIRA in 1996, immigration inspections

took place at the border. See Barbosa da Cunha, 175 F.4th at 98 & n.12

(Cabranes, J., concurring) (collecting cases). Immigration officials were

statutorily required to conduct inspections at ports of entry. 8 U.S.C.

§ 1225(a) (1995). And noncitizens were required to undergo inspection when

making entry at the border or else face deportation or criminal charges.

8 U.S.C. § 1251(a)(1)(B) (1995) (deportable offense); id. § 1325(a) (1995)

(criminal offense). The title’s reference to inspections, then, hints that

§ 1225 focuses on the border. So too does the title’s reference to “arriving

aliens”; a noncitizen arrives in the country when he or she crosses the

border.

Additional border-related language abounds in the body of § 1225.

Subsections (a)(2), (b)(1)(A)(i) & (ii), (b)(1)(F), (b)(2)(C), (c)(1), and (d)(2)(A)

all speak of noncitizens who are “arriving” or who “arrive[].” Further,

subsections (d)(1) and (d)(2) authorize immigration agents to search

20 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 21

vehicles that are “bringing” noncitizens, or in which noncitizens are “being

brought,” into the country. Again, all that happens at the border.

Only a single provision within § 1225, subsection (b)(1)(A)(iii)(II),

mentions or refers to noncitizens in the country’s interior. Unlike that

provision, § 1225(b)(2)(A) does not include language that references

noncitizens who are present in the interior. “When Congress includes

particular language in one section of a statute but omits it in another

section of the same Act, we generally take the choice to be deliberate.”

Badgerow v. Walters, 596 U.S. 1, 11 (2022) (citation modified). So,

Congress’s omission of any reference to the interior in § 1225(b)(2)(A) is

evidence that the subsection does not apply to the interior.

That said, § 1225(b)(2)(A) also lacks the express reference to arriving

noncitizens that limits many other provisions of § 1225 to the border. And

one could argue that this omission implies § 1225(b)(2)(A) is not limited to

the border. See Castañon-Nava, 175 F.4th at 875 (Kirsch, J., dissenting).

What to do with these competing omissions? The answer is that “[t]he force

of any negative implication [] depends on context.” Parrish v. United States,

605 U.S. 376, 389 (2025) (quoting NLRB v. SW Gen., Inc., 580 U.S. 288, 302

(2017)). Given that so many of § 1225’s provisions focus on arrival at the

border while there is only a single outlier that applies to the interior, the

best way to interpret subsection (b)(2)(A)’s dual omissions in context is to

21 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 22

treat subsection (b)(2)(A) like the majority of the other provisions in § 1225

by limiting it to the border. In the absence of express indication otherwise,

we apply the rule and not the exception.

Based on the statutory text and context, we conclude that

§ 1225(b)(2)(A)’s application is limited to the border.

Pushing back against this reasoning, the Government offers several

textual arguments in an effort to persuade us that its reading and

interpretation of § 1225(b)(2)(A) must prevail. We are not convinced.

The Government’s core position is that “applicant for admission,” but

not “seeking admission,” limits § 1225(b)(2)(A)’s scope. Which is to say, the

Government openly asks us to read the phrase “seeking admission” out of

the statute. Since only “applicant for admission” has any force in the

Government’s view, Congress could have more simply drafted

§ 1225(b)(2)(A) to apply “in the case of an alien who is an applicant for

admission, if the examining immigration officer determines that [such]

alien seeking admission is not clearly and beyond a doubt entitled to be

admitted.” Cf. 8 U.S.C. § 1225(b)(2)(A).

The Government’s reading runs afoul of the so-called canon against

surplusage, or the idea that courts should “‘give effect, if possible, to every

clause and word of a statute’” since it is “presum[ed] that each word

22 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 23

Congress uses is there for a reason.” Advoc. Health Care Network v.

Stapleton, 581 U.S. 468, 477–78 (2017) (quoting Williams v. Taylor,

529 U.S. 362, 404 (2000)). It also runs afoul of the related canon that when

Congress “uses certain language in one part of the statute [‘applicant for

admission’] and different language in another [‘seeking admission’],” we

presume “different meanings were intended.” DePierre v. United States,

564 U.S. 70, 83 (2011) (quoting Sosa v. Alvarez-Machain, 542 U.S. 692, 711

n.9 (2004)).

To be sure, these canons are not ironclad rules. Marx v. Gen. Revenue

Corp., 568 U.S. 371, 385 (2013). “Sometimes the better overall reading of

the statute contains some redundancy.” Rimini St., Inc. v. Oracle USA, Inc.,

586 U.S. 334, 346 (2019). And interpreting different language “to mean

roughly the same thing” is not categorically “forbid[den].” Kirtsaeng v. John

Wiley & Sons, Inc., 568 U.S. 519, 540 (2013). However, these canons put a

thumb on the scale in favor of giving “seeking admission” independent

effect, and it is up to the Government to convince us that its redundant

interpretation is the “more natural one.” Stanley v. City of Sanford, 606 U.S.

46, 56 (2025) (citation omitted).

The crux of the Government’s argument is this: An applicant for

admission is, by definition, someone who is applying for admission. Because

applying for something is a form of seeking that thing, it follows that an

23 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 24

applicant for admission is seeking admission. To drive this point home, the

Government borrows an analogy to college applications from the Fifth and

Eighth Circuits. Buenrostro-Mendez, 166 F.4th at 502; Avila, 170 F.4th

at 1134. A college applicant, says the Government, must be applying to that

college and therefore must also be seeking admission there.

On the surface, this argument seems logical. But that surface appeal

is the product of an interpretive sleight of hand. In drawing its analogy to

the college admissions process, the Government relies on “[t]he everyday

meaning” of “applicant for admission.” Buenrostro-Mendez, 166 F.4th

at 502; accord Avila, 170 F.4th at 1134 (using the “ordinary meaning” of the

term). IIRIRA, however, statutorily defines the term “applicant for

admission” as someone who is present in the United States without

admission or who is arriving in the United States. 8 U.S.C. § 1225(a)(1).

This “statutory definition . . . excludes unstated meanings of that term.”

Meese v. Keene, 481 U.S. 465, 484–85 (1987). We must therefore construe

“applicant for admission” as “[IIRIRA] defines that phrase,” not according

to the phrase’s ordinary meaning. Van Buren, 593 U.S. at 387–88 (emphasis

in original).

The Government does not do so. Instead, it conflates ordinary and

statutory meaning. See Lopez-Campos, 175 F.4th at 727–28; Hernandez

Alvarez, 175 F.4th at 1267; Barbosa da Cunha, 175 F.4th at 75–76. When

24 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 25

determining whether Santillan Quiroz is an applicant for admission, the

Government applies the statutory meaning because Santillan Quiroz would

not be an applicant for admission under the term’s ordinary meaning – he

is not applying for anything. But when arguing that “seeking admission”

has no independent effect, the Government abandons that statutory

meaning in favor of the ordinary one. Like Schrödinger’s cat is

simultaneously dead and alive, “applicant for admission” simultaneously

takes on both its ordinary and statutory meanings in the Government’s

hands.

As far as we are aware, no other phrase in the United States Code has

this Schrödinger-esque property. Given that point, one would expect the

Government to have an exceedingly persuasive argument to justify its

interpretive quantum leap. Yet the Government glosses over this

complication in its brief. The Fifth and Eighth Circuits similarly paid scant

attention to the problem in their opinions adopting the Government’s

position. Buenrostro-Mendez, 166 F.4th at 502–03; Avila, 170 F.4th at 1134–

35. The most robust defense of this approach instead comes from our

dissenting colleagues on the Sixth and Eleventh Circuits, which the

Government briefly alluded to during oral argument.

Ordinarily, “[w]e do not consider arguments raised for the first time

at oral argument.” United States v. Anthony, 22 F.4th 943, 952 (10th Cir.

25 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 26

2022). The circumstances here are unique, though. We are construing a

statute, and that construction will apply to everyone in this circuit, not just

the immediate parties to this appeal. As the statutory construction issue “is

properly before the court,” we are “not limited to the particular legal

theories advanced by the parties, but rather retain[] the independent power

to identify and apply the proper construction of governing law.” Kamen v.

Kemper Fin. Servs., Inc., 500 U.S. 90, 99 (1991). Indeed, we would be remiss

to overlook material interpretive arguments just because an immediate

party did not raise them; doing so would run the risk of locking in an

erroneous interpretation. That is especially true here because, as

mentioned, every circuit has now heard argument on the same question,

and each opinion issued thereafter merits consideration by the courts where

the question remains pending. The particularly weighty nature of the

interpretive question here counsels in favor of a fulsome and thorough

analysis.

All this is to say that we will consider the justifications for mandatory

detention set forth in the Sixth and Eleventh Circuit dissents. In doing so,

we respectfully disagree with their reasoning. Their view is that IIRIRA

never actually defines “applicant for admission” because it uses the word

“deemed” when describing applicants for admission in § 1225(a)(1).

Lopez-Campos, 175 F.4th at 743 (Murphy, J., dissenting); Hernandez

26 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 27

Alvarez, 175 F.4th at 1287–89 (Lagoa, J., dissenting). The choice of

“deemed,” as opposed to a word like “means” or “defined,” purportedly

renders § 1225(a)(1) a “legal fiction” rather than a definition. According to

our dissenting colleagues, the legal fiction that ‘a person is deemed to be A’

also deems that person to have all of A’s ordinary attributes and meanings.

See Hernandez Alvarez, 175 F.4th at 1289 (Lagoa, J., dissenting). So, when

§ 1225(a)(1) deems certain noncitizens to be applicants for admission, it also

deems them to be seeking admission.

The word “deemed” cannot bear the weight of the millions of

noncitizens it would potentially subject to detention without bond. For one,

this construction would render the word “deemed” a mousehole hiding an

elephant. See Whitman v. Am. Trucking Ass’ns, 531 U.S. 457, 468 (2001).

“Deemed” is a single word, tucked away in a definitional provision that says

nothing on its face about detention. See 8 U.S.C. § 1225(a)(1). Yet that one

word supposedly upends the country’s system of immigration detention by

mandating the bondless detention of millions. Congress does not rely on

such “subtle device[s]” to make changes of “enormous importance.” Biden v.

Nebraska, 600 U.S. 477, 518 (2023) (Barrett, J., concurring) (quoting MCI

Telecomm’cns Corp. v. Am. Tel. & Tel. Co., 512 U.S. 218, 231 (1994)).

The deeming argument fails substantively, too. It is based on the false

premise that only words like “means” and “defined” can create a statutory

27 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 28

definition. While “means” or “defined” may be the clearest ways to signal

that a provision is definitional, they are not the only ways to do so. Other

phrases like “referred to as” also constitute “quintessential definitional

language.” Pereira v. Sessions, 585 U.S. 198, 213 (2018). So long as a

statutory provision specifically directs how to construe or understand the

meaning of a particular phrase, that provision is definitional.

Measured against this benchmark, “deemed” is definitional. We know

this because the Supreme Court has told us so. In TC Heartland LLC v.

Kraft Foods Group Brands LLC, the Supreme Court analyzed 28 U.S.C.

§ 1391(c), which described a corporation’s residence for purposes of venue.

581 U.S. 258, 262 (2017). Section 1391(c) uses the word “deemed”: A

corporation “shall be deemed to reside, if a defendant, in any judicial district

in which such defendant is subject to the court’s personal jurisdiction with

respect to the civil action in question.” 28 U.S.C. § 1391(c)(2). Even though

the section did not use “means” or “defined,” the Supreme Court thought it

clear that § 1391(c) contained a “definition of corporate ‘residence.’”

TC Heartland, 581 U.S. at 262 (emphasis added). For good reason, too, as a

28 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 29

search of the United States Code shows that Congress frequently uses the

word “deemed” in definition sections. 9

Section 1225(a)(1) is even more clearly definitional than the venue

provision in TC Heartland. While that venue provision generally described

the concept of residence, § 1225(a)(1) tells us how to interpret a particular

phrase, “applicant for admission.” The fact that § 1225(a)(1) is about a

particular term of art also distinguishes it from the three examples of legal

fictions cited in the Eleventh Circuit dissent. Hernandez Alvarez, 175 F.4th

at 1288–90 (Lagoa, J., dissenting). Only one of those examples, Sturgeon v.

Frost, involved a deeming clause. 587 U.S. 28, 47 (2019) (citing 16 U.S.C.

§ 3103(c)). But that deeming clause was clearly not a definition because it

did not purport to give meaning to a particular term of art. See 16 U.S.C.

§ 3103(c). The remaining two examples did not interpret statutory deeming

provisions at all. Leng May Ma v. Barber, 357 U.S. 185 (1958); Kaplan v.

9 E.g., 15 U.S.C. § 769 (“(1) any reference to ‘function’ or ‘functions’

shall be deemed to include . . .”; etc.); 22 U.S.C. § 3602(b) (“‘Canal Zone’ shall be deemed to refer to . . .”; etc.); 26 U.S.C. § 7701(a)(51)(E)(ii) & (iii) (“such entity shall be deemed to be a foreign-controlled entity”; etc.); 33 U.S.C. § 1107 (“the term ‘marine science’ shall be deemed to apply to . . .”; etc.); 46 U.S.C. § 12101(a) (“In this chapter, a vessel is deemed to have been rebuilt in the United States only if . . .”); 50 U.S.C. § 3814(b)–(f) (“The term ‘United States’, when used in a geographical sense, shall be deemed to mean . . .”; etc.) (all emphases added).

29 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 30

Tod, 267 U.S. 228 (1925). It is therefore best to understand § 1225(a)(1)’s

use of the word “deemed” as creating a definition, not a legal fiction.

Even if § 1225(a)(1) created a legal fiction, we are not so sure that

legal fictions behave in the way our colleagues posit. Courts interpreting a

statute “will not attribute words to Congress that it has not written.”

Atl. Sounding Co. v. Townsend, 557 U.S. 404, 424 (2009). When Congress

deems a person as ‘A’ but remains silent about whether that person is also

deemed as ‘B,’ we should not infer that Congress meant to deem the person

as ‘B,’ too. That is true even if ‘A’ and ‘B’ are related in their ordinary usage,

like “applicant for admission” and “seeking admission” may be. See Torres

v. Barr, 976 F.3d 918, 928–29 (9th Cir. 2020) (en banc) (when § 1225(a)(1)

deems a noncitizen to be an “applicant for admission,” it does not also deem

that noncitizen to have made “an actual application for admission”). “[W]e

will not speculate that Congress meant what it did not say,” so we interpret

§ 1225(a)(1) to deem noncitizens as applicants for admission only, not to

also deem them as seeking admission. Tank v. Chronister, 160 F.3d 597, 600

(10th Cir. 1998).

30 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 31

In sum, the “deemed” argument advanced by the Sixth and Eleventh

Circuit dissents does not justify the Government’s position. 10 That leaves

the Government’s contextual arguments, which fare no better than its

textual ones.

The Government makes five contextual arguments that we now

address in turn. First, the Government directs us to § 1225(a)(3), which

10 We briefly address two other points raised in these dissents. The

Sixth Circuit dissent asserts that the Government’s interpretation does not actually render “seeking admission” superfluous. Lopez-Campos, 175 F.4th at 742 (Murphy, J., dissenting). The dissent believes that “seeking admission” does independent work because it excludes from § 1225(b)(2)(A)’s ambit all noncitizens who “withdraw” their applications. Id. That is not how the Government’s interpretation works. The Government’s interpretation treats noncitizens as seeking admission solely based on their status as applicants for admission, not on any action that they do or do not take. And to the extent that the dissent would treat a noncitizen as “constructive[ly]” seeking admission by entering the country and “withdraw[ing]” that application by departing, it would create surplusage in yet another subsection of the statute. See id.; 8 U.S.C. § 1225(a)(4) (treating withdrawal and departure as separate events).

The Eleventh Circuit dissent refers to “applicant for admission” and “seeking admission” as a doublet to which the surplusage canon does not apply. Hernandez Alvarez, 175 F.4th at 1295–96 (Lagoa, J., dissenting). But the dissent does not explain what makes something a doublet other than a court’s say-so. In any event, recognized doublets include phrases like “cease and desist” or “free and clear.” In re Ocwen Loan Servicing, LLC Mortg. Servicing Litig., 491 F.3d 638, 646 (7th Cir. 2007). “Applicant for admission” and “seeking admission,” which appear in completely different clauses of § 1225(b)(2)(A), do not resemble a doublet.

31 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 32

requires immigration officers to inspect “[a]ll aliens . . . who are applicants

for admission or otherwise seeking admission.” 8 U.S.C. § 1225(a)(3). It

contends that the use of “or otherwise” to link “applicants for admission”

with “seeking admission” shows that applicants for admission are a subset

of those seeking admission. And so, the Government asserts, applicants for

admission must be seeking admission.

We agree that “or otherwise” can indicate a subset-superset

relationship. See Barbosa da Cunha, 175 F.4th at 78–79. But the phrase

does not always establish such a relationship. “Or otherwise” can also

simply refer to something different. Id.

It is easy to find examples where “or otherwise” does not have the

Government’s preferred meaning. In Helsinn Healthcare S.A. v. Teva

Pharmaceuticals USA, Inc., the Supreme Court construed the phrase “in

public use, on sale, or otherwise available to the public.” 586 U.S. 123, 125

(2019) (emphasis added) (quoting 35 U.S.C. § 102(a)(1)). One party claimed

that the statute’s use of “or otherwise” must make “on sale” a subset of

“available to the public” such that private sales were not included. Id.

at 132. The Supreme Court rejected this subset argument and held that

private sales did fall under the statute. Id.

Similarly, immigration law defines “falsely make” as submitting a

document that “contains a false, fictitious, or fraudulent statement or

32 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 33

material representation . . . or otherwise fails to state a fact which is

material.” 8 U.S.C. § 1324c(f) (emphasis added). Put differently, a person

“falsely makes” when submitting an affirmative misrepresentation “or

otherwise” omitting a material fact. However, affirmatively saying

something false is different from, not a subset of, failing to say a fact.

The bottom line is that the meaning of “or otherwise” in a statute is

context dependent. Yet nothing in § 1225(a)(3) disambiguates between the

Government’s preferred subset-superset meaning and the simpler

“something different” meaning. Without that disambiguation, § 1225(a)(3)

does not compel the conclusion that all applicants for admission are

necessarily seeking admission. Thus, § 1225(a)(3)’s “or otherwise” language

does not turn the argument in the Government’s favor.

Second, the Government cites § 1225(a)(5), which provides that “[a]n

applicant for admission may be required to state under oath any

information sought by an immigration officer regarding the purposes and

intentions of the applicant in seeking admission to the United States.”

8 U.S.C. § 1225(a)(5). If applicants for admission can be asked questions

when they seek admission, this shows that applicants for admission are

seeking admission. Or at least, so the Government asserts.

However, that conclusion does not follow from either § 1225(a)(5)’s

grammatical or logical structure. All that subsection (a)(5) demonstrates is

33 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 34

that applicants for admission can be seeking admission, not that they must

be. A counterexample makes this apparent: “A person may be asked to

provide any allergy information to his server in ordering food at a

restaurant.” This sentence has the same grammatical and logical structure

as § 1225(a)(5). It does not mean, though, that all persons are necessarily

ordering food at a restaurant. Rather, it means that if persons happen to

order food at a restaurant, they may be asked to provide allergy information

to their server.

Third, the Government claims that limiting § 1225(b)(2)(A) to the

border would create its own surplusage by making that section duplicative

of § 1225(b)(1), which is also limited to the border. But subsection (b)(1)

serves an important function at the border that subsection (b)(2)(A) does

not. Subsection (b)(1) funnels a subset of noncitizens encountered at the

border (those inadmissible under 8 U.S.C. §§ 1182(a)(6)(C) and 1182(a)(7))

into expedited removal proceedings through which they can be removed

“without further hearing or review.” 8 U.S.C. § 1225(b)(1)(A)(i); accord

8 C.F.R. § 235.3. By contrast, subsection (b)(2)(A) is the catchall for

noncitizens at the border who are not subject to expedited removal (those

inadmissible on grounds other than the two identified above) and provides

that those noncitizens will receive full removal proceedings “under section

1229a.” 8 U.S.C. § 1225(b)(2)(A).

34 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 35

Fourth, the Government asserts that Santillan Quiroz’s

interpretation of “seeking admission” nullifies the definition of “applicant

for admission.” According to the Government, this is because “applicant for

admission” is defined to include noncitizens in the interior, but every time

the phrase appears in the statute, “seeking admission” excludes such

noncitizens. See Buenrostro-Mendez, 166 F.4th at 504. So, half of the

definition of “applicant for admission” does no work. That is incorrect.

The only time “seeking admission” limits “applicant for admission” is

in § 1225(b)(2)(A). Although “seeking admission” appears together with

“applicant for admission” in § 1225(a)(3), the two phrases appear in the

disjunctive, meaning that one does not limit the other. “Applicant for

admission” therefore takes on its full scope in § 1225(a)(3). Additionally, the

definition of “applicant for admission” is not restricted to § 1225. The

definition applies “for purposes of [the entire] chapter,” i.e., the entire INA.

8 U.S.C. § 1225(a)(1). And elsewhere, the INA sets standards of proof for

removal proceedings based on whether a noncitizen is an applicant for

admission or not. 8 U.S.C. § 1229a(c)(2). In that section, the phrase “seeking

admission” does not even appear and therefore cannot conflict with

“applicant for admission.”

Thus, the structure of our immigration laws is rational. Congress

imposed a broad definition of “applicant for admission” to be used

35 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 36

throughout our immigration laws. It then narrowed the term’s scope in

§ 1225(b)(2)(A) specifically.

Fifth, and finally, the Government suggests that adopting Santillan

Quiroz’s interpretation will create difficult line-drawing questions on how

to apply § 1225(b)(2)(A) in practice. How far from the border, and how soon

upon crossing the border, must a noncitizen be detained such that

§ 1225(b)(2)(A) applies? Those questions may well pose challenges in

individual cases. But the existence of line-drawing challenges is

unremarkable. “[T]he constant business of the law is to draw such lines,”

Dominion Hotel v. Arizona, 249 U.S. 265, 269 (1919), and “the law is full of

instances” that “depend[] on . . . some matter of degree.” Cf. Johnson v.

United States, 576 U.S. 591, 604 (2015) (quoting Nash v. United States,

229 U.S. 373, 377 (1913)). Courts cannot rewrite a statute’s plain terms just

to avoid hard cases.

In all, the Government’s textual and contextual 11 arguments don’t

move the needle. Nothing about those arguments convinces us to depart

11In appeals before other circuits, the Government has pointed to supposed tension between our interpretation of “seeking admission” and a similar phrase in the INA’s humanitarian parole provision, “applying for admission.” 8 U.S.C. § 1182(d)(5)(A). Suffice to say that whatever tension might exist in other circuits’ caselaw, it does not exist here because neither this court nor the Supreme Court have previously construed “applying for admission” inconsistently with “seeking admission.”

36 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 37

from our conclusion that § 1225(b)(2)(A) is limited to the border, and that

Santillan Quiroz is an “applicant for admission” but not “seeking

admission.”

C

Reading § 1225(b)(2)(A) together with § 1226(a) also supports the

conclusion that § 1225(b)(2)(A) is restricted to the border. Recall that

§ 1226(a) provides another source of detention authority pending removal

proceedings. As we will explain, that detention authority includes at least

some inadmissible noncitizens within its scope. The Government’s

interpretation, however, would remove all inadmissible noncitizens from

§ 1226(a)’s scope.

To see why § 1226(a) must apply to at least some inadmissible

noncitizens, we start with its text. Section 1226(a) authorizes the

Government to detain a noncitizen “pending a decision on whether the alien

is to be removed from the United States.” 8 U.S.C. § 1226(a). Removal

proceedings cover those who are inadmissible, which in turn suggests that

§ 1226(a) authorizes the detention of inadmissible noncitizens. See

Kawashima, 565 U.S. at 481 n.2. Section 1226(c) confirms this. As noted

earlier, noncitizens detained under § 1226(a) are generally eligible for bond.

8 U.S.C. § 1226(a)(2). But § 1226(c) creates exceptions to that general rule,

including specific exceptions for inadmissible noncitizens. 8 U.S.C.

37 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 38

§§ 1226(c)(1)(A), (D), (E). There would be no need for § 1226(c) to provide

such exceptions unless § 1226(a) applied to at least some inadmissible

noncitizens.

The Government’s interpretation disrupts § 1226(a)’s coverage of

inadmissible noncitizens. If the Government is correct that § 1225(b)(2)(A)

mandates the detention of all applicants for admission, then there are no

inadmissible noncitizens left for § 1226(a) to cover. See 8 U.S.C. § 1225(a)(1)

(applicants for admission are unadmitted and/or arriving); Judulang,

565 U.S. at 46 (grounds of inadmissibility apply to those who are

unadmitted or arriving). Consequently, the subsections of § 1226(c)

addressing inadmissible aliens would be rendered useless since there would

be no inadmissible aliens to except from bond eligibility under § 1226(a).

This creates a surplusage problem, and a big one, because the surplusage

canon “applies with special force” when an interpretation would render

“‘entire subparagraph[s] meaningless.’” Pulsifer v. United States, 601 U.S.

124, 143 (2024) (quoting Nat’l Ass’n of Mfrs. v. Dep’t of Defense, 583 U.S.

109, 128 (2018)).

The Government answers this problem by asserting that § 1226(c) is

a standalone limitation on the release of noncitizens being held in

detention. Thus, it says, those parts of § 1226(c) that refer to inadmissible

aliens still have an effect on other detention authorities, just not on

38 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 39

§ 1226(a). The problem with this argument is that the Supreme Court has

squarely rejected the interpretation of § 1226(c) “as establishing [a]

separate source[] of arrest and release authority” apart from § 1226(a).

Nielsen v. Preap, 586 U.S. 392, 409 (2019). To the contrary, the Court held

that § 1226(c) “is simply a limit on the authority conferred by” § 1226(a). Id.

This makes good sense, as § 1226(c) lacks language indicating Congress

intended for it to apply beyond the confines of § 1226. Language that, we

add, Congress readily used elsewhere in our immigration laws. See, e.g.,

8 U.S.C. § 1225(a)(1) (“for purposes of this chapter”); 8 U.S.C. § 1101(a) (“As

used in this chapter”); 8 U.S.C. § 1101(h) (“For purposes of section

1182(a)(2)(E) of this title”).

The Laken Riley Act, Pub. L. No. 119-1, 139 Stat. 3 (2025), only

reinforces this conclusion. Congress passed the Act last year on January 29,

2025. Id. At the time of the Act’s passage, the Government had not yet

adopted its current view that § 1225(b)(2)(A) applies to the interior; its

longstanding and nearly thirty-year-old interpretation – that

§ 1225(b)(2)(A) was limited to the border – still stood. Against that

backdrop, the Laken Riley Act did not extend § 1225(b)(2)(A)’s bondless

detention mandate to the country’s interior. Rather, the Act added a new

exception to § 1226(c), one that specifically prohibited certain inadmissible

39 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 40

noncitizens from seeking a bond. Laken Riley Act § 2 (codified at 8 U.S.C.

§ 1226(c)(1)(E)).

“When Congress adopts a new law against the backdrop of a

‘longstanding administrative [or judicial] construction,’ [courts] generally

presume[] the new provision should be understood to work in harmony with

what has come before.” Monsalvo v. Bondi, 604 U.S. 712, 725 (2025) (quoting

Haig v. Agee, 453 U.S. 280, 298 (1981)); accord Lamar, Archer & Cofrin,

LLP v. Appling, 584 U.S. 709, 722 (2018) (citations omitted). Here, the

backdrop was the Government’s longstanding interpretation that § 1225

applied at the border while § 1226 applied to the interior, 62 Fed. Reg.

at 10323; the Supreme Court’s endorsement of the same in Jennings,

583 U.S. at 287–89; and the Supreme Court’s holding that the § 1226(c)

exceptions do not stand independent from § 1226(a), Nielsen, 586 U.S.

at 409. The Laken Riley Act did not include language to change any of those

holdings or interpretations even though it amended both § 1225 and § 1226.

See Laken Riley Act §§ 2–3. The Act therefore ratified the understanding

and practice that § 1225(b)(2)(A) applies at the border while § 1226(a)

applies to the interior. See Lorillard v. Pons, 434 U.S. 575, 580 (1978).

D

Next, we address the Government’s statutory purpose argument, a

theme running through the entirety of the Government’s position.

40 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 41

According to the Government, the purpose of IIRIRA was to correct a gross

inequity between noncitizens stopped at the border and those who

unlawfully entered the country’s interior. That is, IIRIRA aimed to “replace

certain aspects of the [] ‘entry doctrine,’ under which illegal aliens who have

entered the United States without inspection gain equities and privileges

in immigration proceedings that are not available to aliens who present

themselves for inspection at a port of entry.” H.R. Rep. 104-469, pt. 1 at 225

(1996). Allowing for release on bond in the country’s interior, but not at the

border, is one such inequity that the Government believes IIRIRA was

meant to fix.

While the Government’s account is plausible, and many may agree

with it as a matter of policy, it finds little purchase as an interpretive aid.

All “laws are the product of compromise, and no law pursues its purposes

at all costs.” Luna Perez v. Sturgis Pub. Schs., 598 U.S. 142, 150 (2023)

(citation modified). In this case, the legislative history confirms that IIRIRA

was a product of compromise: Congress reported that IIRIRA was meant to

replace only “certain aspects” of the prior entry-based regime. H.R. Rep.

104-469, pt. 1 at 225 (emphasis added). It is easy to imagine why Congress

might not have wanted to extend mandatory detention into the country’s

interior even as it equalized in other ways the treatment between

noncitizens stopped at the border and those who entered unlawfully.

41 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 42

Possibly Congress was worried that there were insufficient resources

to detain all noncitizens unlawfully present in the interior. Maybe it

thought that, even if there were sufficient resources, humanitarian reasons

counseled against such detention since noncitizens in the interior had likely

established intimate connections with their friends, neighbors, and

communities. Congress may simply have concluded that detention in the

interior wasn’t necessary: the usual purpose of civil immigration detention

is to prevent noncitizens from absconding to avoid removal, but those with

strong connections to the community are less likely to do so. Or Congress

may have had constitutional concerns because due process protections are

far stronger for noncitizens inside the country than at the border. See

Kwong Hai Chew v. Colding, 344 U.S. 590, 596 n.5 (1953).

Perhaps some of these reasons motivated Congress. Perhaps none did.

It is impossible to tell and beside the point. What matters is that the

seemingly straightforward legislative tale of equalizing treatment between

arriving and unlawfully entered noncitizens is much more nuanced and

complex than the Government would have us all believe.

In any case, the role of the court is not to impose its views of optimal

immigration policy. Its job is simply to apply the law as written. In other

words, “we will not presume with [the Government] that any result

consistent with [its] account of the statute’s overarching goal must be the

42 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 43

law but will presume more modestly instead ‘that [the] legislature says . . .

what it means and means . . . what it says.’” Henson v. Santander Consumer

USA Inc., 582 U.S. 79, 89 (2017) (third alteration in original) (quoting Dodd

v. United States, 545 U.S. 353, 357 (2005)). Because “purposive argument []

cannot overcome the force of the plain text,” we reject the Government’s

position that statutory purpose requires us to extend § 1225(b)(2)(A)’s

mandatory detention to noncitizens arrested in the country’s interior.

Mohamad v. Palestinian Auth., 566 U.S. 449, 460 (2012).

E

Although the text and context discussed above are sufficient to answer

the interpretive question in this appeal, we close with a brief discussion on

the doctrine of constitutional avoidance, which further supports our

conclusion. Constitutional avoidance, in its strongest form, counsels us

against interpreting statutes in ways that raise serious constitutional

concerns. Zadvydas v. Davis, 533 U.S. 678, 689 (2001). The mandatory

detention of potentially millions of noncitizens without the potential for

bond raises exactly such serious concerns.

The Due Process Clause of the Constitution forbids the Government

from “depriv[ing]” any “person . . . of life, liberty, or property, without due

process of law.” U.S. Const. amend. V. “Freedom from imprisonment – from

government custody, detention, or other forms of physical restraint – lies at

43 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 44

the heart of the liberty that [this] Clause protects.” Zadvydas, 533 U.S.

at 690. Due process requires that, whenever the Government detains

somebody, it must have a good reason for doing so. Id. If the detention is

civil and nonpunitive, like the immigration detention here, that reason

must rise to the level of a “strong special justification.” Id. Adopting the

Government’s interpretation of § 1225(b)(2)(A) would pose grave

constitutional problems because there is little justification, let alone a

strong one, for detaining every one of the millions of unadmitted noncitizens

in our country. 12

We acknowledge that immigration is a unique area when it comes to

due process. In Demore v. Kim, the Supreme Court held that the

Government has significant leeway when it comes to immigration

detention. See 538 U.S. 510 (2003). The Court explained, “[i]n the exercise

of its broad power over naturalization and immigration, Congress regularly

makes rules that would be unacceptable if applied to citizens.” Id. at 521

(quoting Mathews v. Diaz, 426 U.S. 67, 79–80 (1976)). The Court also

12 To the extent it matters, we assume for sake of argument that questions about the types of justifications capable of supporting detention sound in substantive due process, while questions about procedures used for proving the satisfaction of a given justification sound in procedural due process. In that regard, our discussion of constitutional avoidance sounds in substantive due process.

44 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 45

“recognized detention during deportation proceedings as a constitutionally

valid aspect of the deportation process.” Id. at 523.

But the Supreme Court has never said that due process protections

fall away completely in the immigration context. Quite the opposite. “It is

well established that the Fifth Amendment entitles aliens to due process of

law in deportation proceedings.” Reno v. Flores, 507 U.S. 292, 306 (1993).

Likewise, the Court did not hold in Demore that detention for its own sake

is constitutional just because detention occurs during removal proceedings.

At most, Demore stands for the proposition that individualized findings are

not always necessary to justify detention in the immigration context, and

that categorical findings may sometimes be sufficient.

In Demore, the Court held that categorical, legislative findings were

sufficient to justify mandatory detention under § 1226(c). In sustaining the

provision’s constitutionality, the Court relied on Congress’s extensive

findings that it was necessary to mandate the detention of certain

removable noncitizens who had been convicted of crimes. Demore, 538 U.S.

at 518–20, 528. The Court observed that when enacting § 1226(c), Congress

relied on studies showing some convicted noncitizens posed a potential

danger to society due to high recidivism risk, and that allowing bond “would

lead to an unacceptable rate of flight.” Id. at 518, 520.

45 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 46

The precedents that Demore cited to justify across-the-board

detention also involved categorical determinations that such detention was

necessary. For instance, it cited to Carlson v. Landon, 342 U.S. 524 (1952),

which dealt with mandatory detention of noncitizens who had participated

in Communist activities. See Demore, 538 U.S. at 523. Various noncitizens

argued that they should be released if they could show they were not flight

risks, but the Court rejected that argument on the basis of legislative

findings, what the Court referred to as “Congress’ understanding of

[Communists’] attitude toward the use of force and violence.” Carlson,

342 U.S. at 541. Put differently, it satisfied due process for Congress to

make a finding that Communists as a category were “a menace to the

security of the United States.” Id. Similarly, Demore cited to Reno v. Flores.

See Demore, 538 U.S. at 526. And in Reno, the Court ratified the use of

“blanket presumption[s],” and “generic rules” based on those presumptions,

to justify immigration detention. 507 U.S. at 313 (internal quotation marks

omitted).

In both cases, the Government provided some justification for

detention, albeit on a categorical or class-wide basis. No such class-wide

findings exist here that would justify mandatory detention of every single

unadmitted noncitizen.

46 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 47

All that said, this court need not and does not determine in this case

whether the Government’s position is unconstitutional. The doctrine of

constitutional avoidance instructs us to avoid the Government’s

interpretation so long as it raises serious constitutional questions, and that

it does. Thus, constitutional avoidance is another reason to limit

§ 1225(b)(2)(A) to the border.

IV

We conclude by recognizing again the stakes of this dispute over

statutory interpretation. In our circuit, thousands of noncitizens are likely

subject to mandatory detention under the Government’s newfound

statutory reading and policy. Many more legal battles over this policy are

currently playing out in courts across the country. Five circuits have

already weighed in. Ultimately, only one court, the Supreme Court, can

settle this issue once and for all.

But in this case and for this circuit, we are tasked with deciding

whether this petitioner, Santillan Quiroz, must continue to be detained

without even a bond hearing. He need not.

47 Appellate Case: 26-6019 Document: 91-1 Date Filed: 06/30/2026 Page: 48

REVERSED AND REMANDED. 13

13 On remand once the mandate issues, the district court must grant Santillan Quiroz’s petition forthwith. Because Santillan Quiroz can properly be subject to detention under § 1226(a), though, the district court shall order the Government to, within seven days of such order, either provide him with a bond hearing or else release him. See Aplt. App. at 10; Requejo Roman v. Castro, 816 F. Supp. 3d 1267, 1285 (D.N.M. 2026).

Any petition for rehearing is due within fourteen days after judgment is entered by this court.
