JERRY E. SMITH, Circuit Judge:
Samuel Gomez petitioned for review of two orders of the Board of Immigration Appeals (“BIA”) finding him ineligible for adjustment of status, ordering his removal, and denying his motion to reopen. We issued an opinion affirming the BIA’s factual determination that Gomez had not been lawfully admitted into the United States and was therefore ineligible for adjustment of status and was removable as an inadmissible alien. We granted the parties’ joint motion to withdraw that opinion and, after considering the new evidence and supplemental briefing, we grant the petition for review and remand.
I.
Gomez, a citizen of El Salvador, entered the United States without admission or parole in the early 1980s. He was granted temporary resident status by applying for amnesty under the Immigration Reform and' Control Act of 1986 and was given a one-year temporary resident card in May 1992 (expiring May 1993). In 2005, his application for asylum was denied, but he received temporary protected status (“TPS”), which expired in 2009, and his application for renewal was denied.
In June 2010, Gomez was served with a notice to appear charging removability as an alien present without admission or parole in violation of 8 U.S.C. § 1182(a)(6)(A)(i). He sought an adjustment of status under Section 245(a) of the Immigration and Nationality Act (“INA”), which provides that, at the discretion of the Attorney General, an alien lawfully inspected and admitted or paroled into the United States may have his status adjusted to that of an alien lawfully admitted for permanent residence (subject to certain requirements not relevant here).
See
8 U.S.C. § 1255(a).
An immigration judge (“IJ”) held an evi-dentiary hearing to determine whether Gomez was eligible for adjustment. The main issue was whether he had ever been lawfully admitted. He produced evidence that he had traveled to El Salvador in 1993 and returned on a flight to Houston. He claimed that he had been inspected and admitted at the airport’s immigration checkpoint in the ordinary course, but he had no immigration documents to support that assertion. The government submitted Gomez’s TPS applications, on which he represented that he had most recently entered the United States without inspection at an immigration checkpoint. Gomez claimed that he had misunderstood the forms, which he thought required him to indicate how he had
initially
entered the United States in the 1980s.
After the hearing, the government successfully moved to pretermit the application for adjustment of status. The IJ determined that Gomez was not eligible for an adjustment. First, the IJ said that Gomez had not satisfied his burden of showing that he was ever lawfully admitted. And second, the IJ reasoned that, even if Gomez had been lawfully admitted in 1993 as he claimed, expiration of his status as a temporary resident would have terminated the legal effect of that admission under 8 C.F.R. § 245a.2(u)(4) (the regulation governing the expiration of temporary resident status under the 1986 amnesty). At a later hearing, the IJ ordered Gomez removed to El Salvador.
The BIA affirmed both of the IJ’s rulings. Gomez filed a motion to reopen, which the BIA also denied. Gomez petitioned timely for review. After briefing
and oral argument, we issued an opinion affirming the BIA’s factual determination that Gomez was never lawfully admitted. We therefore did not reach the agency’s legal determination that, even if Gomez
had
been lawfully admitted in 1993, the expiration of his temporary resident status rendered that admission nugatory..
The parties jointly moved to vacate. After representing throughout the litigation that there was no record of Gomez’s purported 1993 admission (and asserting at oral argument that records from the relevant time period did not exist
at all),
the government reversed course. Now, it informs us, by letter, that it has located records confirming that Gomez
was
in fact processed normally through a Houston immigration checkpoint in 1993. We granted the motion to vacate and accepted supplemental briefing on the proper interpretation and application of Section 245a.2(u)(4). In its supplemental brief, the government explicitly concedes that Gomez was admitted in 1993. The only basis on which it defends the BIA’s order is that the regulation renders that admission legally ineffective. Thus, the question is whether the regulation’s language stating that Gomez returned “to the unlawful status held prior to” his adjustment to temporary resident status undoes Gomez’s 1993 admission.
II.
Ordinarily, we review the BIA’s legal conclusions
de novo. Rodriguez-Avalos v. Holder,
788 F.3d 444, 448 (5th Cir. 2015) (per curiam). But the BIA is entitled to significant deference when it interprets its own ambiguous regulations.
See Auer v. Robbins,
519 U.S. 452, 461, 117 S.Ct. 905, 137 L.Ed.2d 79 (1997). That is so even when the agency interprets an immigration regulation in a single-member, nonprecedential opinion.
Auer
deference is
typically strong; the agency’s interpretations, even if relatively informal (as in this nonprecedential, single-member BIA opinion), are given “controlling weight....”
But deference is “unwarranted when there is reason to sqspect that the agency’s interpretation ‘does not reflect the agency’s fair and considered judgment on the matter in question[,]’ ” as where “the agency’s interpretation conflicts with a prior interpretation.”
Christopher v. SmithKline Beecham Corp.,
— U.S. -, 132 S.Ct. 2156, 2166-67, 183 L.Ed.2d 153 (2012) (quoting Auer, 519 U.S. at 462, 117 S.Ct. 905).
Thus, to decide how to approach the interpretive issue, we first must determine whether Section 245a.2(u)(4) is ambiguous. If it is, we must decide whether the BIA’s interpretation of it here represents its fair and considered judgment regarding the proper interpretation. If it is the agency’s fair and considered judgment, we must declare whether the agency’s interpretation is a reasonable one.
Although we conclude that the regulation is ambiguous, deference here is inappropriate because the BIA’s interpretation of this regulation has not been consistent. Therefore, we do not continue to the third step of the
Auer
inquiry but instead interpret the regulation
de novo.
Surprisingly, the government did not brief any arguments invoking or analyzing
Auer
deference. Instead, it urges only
Skidmore
deference, under which we defer to an agency’s interpretation merely for its persuasive power: its “thoroughness evident in its consideration, the validity of its reasoning, its consistency with earlier and later pronouncements,” and the like.
Skidmore v. Swift & Co.,
323 U.S. 134, 140, 65 S.Ct. 161, 89 L.Ed. 124 (1944).
Skid-more
calls for significantly less deferential review than does
Auer.
Under
Auer,
an agency’s interpretation of its own ambiguous regulation is typically given “controlling weight,” while
Skidmore
demands only that we pay respectful attention to the agency’s interpretation.
Belt,
444 F.3d at 416.
The government’s failure to brief the more deferential
Auer
standard apparently stems from its reliance on language in
Rodriguez-Avalos,
788 F.3d at 449 & n.8. There, we stated that Chevron
deference applies when we review the BIA’s “interpretation of the statutes
and regulations
it administers when its interpretations are precedential.... ”
Id.
at 449 (emphasis added). “Comparatively, when examining the BIA’s interpretation of an ambiguous provision of a statute it administers that was rendered in a non-precedential BIA decision, we use the standard announced in Skidmore....”
Id.
at 449 n.8.
The first statement is inexact, because regulatory interpretations in precedential agency rulings receive
Auer,
not
Chevron,
deference.
The second statement, from the footnote, is strictly correct but could be read, in context, as suggesting that
Skidmore
deference applies to agency
regulatory
interpretations issued in nonprece-dential opinions. Our caselaw does not support that possible reading. We have applied
Auer
deference to a variety of relatively informal agency determinations, including those in opinion letters, agency operating handbooks, and litigation briefs.
See Belt,
444 F.3d at 415.
Despite the government’s choice to claim only
Skidmore
deference, “it is this court, and not the parties, that must determine the appropriate standard of review.”
The difference is immaterial here, however, because we decline to defer to the agency interpretation under even the more forgiving standard.
A.
We find 8 C.F.R. § 245a.2(u)(4) ambiguous. It reads as follows:
Return to unlawful status after termination. Termination of the status of any alien previously adjusted to lawful temporary residence under section 245A(a) of the Act shall act to return such alien to the unlawful status held prior to the adjustment, and render him or her amenable to exclusion or deportation proceedings under section 236 or 242 of the Act, as appropriate.
The regulation is ambiguous because the meaning of the phrase “return such alien to the unlawful status held prior to the adjustment” is opaque. It is not obvious whether the “unlawful status” to which an alien returns encompasses his lack of a lawful admission at the time he adjusted to temporary resident status. Indeed, the regulation does not mention admission at all.
Further, despite its centrality in modern immigration law, the term “status” is not defined in the relevant statutes or regulations.
See Tula Rubio v. Lynch,
787 F.3d 288, 293 (5th Cir. 2015). And as Gomez reminds us, status and admission are, at least in many applications, distinct concepts in immigration law. A person can be in unlawful status despite a valid admission (as when a tourist overstays his visa). And a person can be admitted without any legal entitlement to be present in the country.
Matter of Quilantan,
25 I. & N. Dec. 285, 290-91 (BIA 2010). Thus, the plain text of the regulation does not answer the question whether the expiration of Gomez’s temporary resident status undid the legal effect of his 1993 admission, thereby rendering him ineligible for adjustment of status. The regulation is ambiguous.
B.
Because the regulation is ambiguous, we have to determine whether the BIA’s opinion represents the agency’s considered judgment of how it should be interpreted. That is not a hard standard to satisfy — the Supreme Court and this circuit have blessed a wide variety of fairly casual agency pronouncements. But the Supreme Court has specifically warned that deference is improper where there is a strong reason to believe that the agency’s interpretation is
not
in fact an expression of its considered judgment, and inconsistencies in the agency’s interpretive pronouncements are sufficient reason so to believe.
See Christopher,
132 S.Ct. at 2166-67.
The BIA’s interpretation of Section 245a.2(u)(4) has not been consistent. In
In re Castro Valdez,
2012 WL 3911586, at *3 (BIA Aug. 13, 2012), the agency reached a contrary result on nearly identical facts. The alien entered without inspection but was granted temporary resident status during the amnesty. While a temporary resident, he departed the United States and, upon return, was admitted as a lawful temporary resident. Later, his application for permanent residency was denied, and he lost his temporary-resident status.
Id.
The Attorney General initiated removal proceedings, claiming that the petitioner was inadmissible as an alien present without admission or parole.
Id.
The IJ rejected that theory because it found that the alien
had
in fact been lawfully admitted after his trip out of the United States.
Id.
at *2.
On appeal to the BIA, the government urged that the IJ had erred, because Section 245a.2(u)(4) meant that expiration of temporary resident status nullified the legal effect of the admission that the alien had obtained as a result of that status.
Id.
at *2-3. The BIA rejected that argument, reasoning, as Gomez does here, that the alien’s return to his previous unlawful status did not alter the fact that he had been admitted.
Id.
at *3. It therefore affirmed the IJ’s decision to terminate the removal proceeding.
Id.
Thus, in a nearly identical case, the BIA interpreted the regulation in precisely the opposite fashion from how it does now. Those contradictory interpretations show that its current litigation position does not represent the agency’s considered and expertise-driven judgment as to the correct reading of Section 245a.2(u)(4). Therefore, following
Christopher,
we decline to defer to the agency’s proposed interpretation and, instead, review it
de novo.
III.
The BIA erred in interpreting 8 C.F.R. § 245a.2(u)(4). The government says that the regulation means that Gomez returned to his previous status and that his previous status was “present without admission.” Gomez disagrees, reasoning that there is no such status. By his account, admission and status are fundamentally different concepts, and a return to his previous unlawful
status
would not affect his 1993
admission.
Rather, returning to unlawful status means only that he no longer had affirmative permission to be in the United States.
To resolve this dispute, we must determine what it means for Gomez to return to his previous unlawful status. Gomez is correct: His return to unlawful status had no effect on his 1993 admission. That is because there are no fine-grained distinctions between and among various forms of unlawful status, so there is no status of “present without admission” to which Gomez could return.
Admission and status are fundamentally distinct concepts. Admission is an occurrence, defined in wholly factual and procedural terms: An individual who presents himself at an immigration checkpoint, undergoes a proeedurally regular inspection, and is given permission to enter has been admitted, regardless of whether he had any underlying legal right to do so.
Quilantan,
25 I. & N. Dec. at 290-91. Status, by contrast, usually describes the type of permission to be present in the United States that an individual has.
See
Steel on Immigeation Law §§ 2:23, 3:1 (2015 ed.).
Thus, aliens who enter lawfully have ‘immigrant’ or ‘nonimmigrant’ status and have various subsidiary descriptions within those categories, depending on their
specific characteristics.
In contrast to the INA’s extensive enumeration of different types of legal presence in the United States,
there is no analogous enumeration of different categories of illegal presence — ■ those illegally present are just “without status” or in “unlawful status.”
Those phrases mean only that the alien lacks permission to be present.
Because the concepts are separate, an alien can be admitted despite the absence of any lawful status, as when an immigration officer accidentally processes him through a checkpoint. Or an alien who was admitted in a lawful status can acquire unlawful status, as by overstaying a visa— but that does not mean he was never admitted. Conversely, an alien can have lawful status without any factual admission at all.
To be clear, lack of admission can
cause
an alien to be in unlawful status, but it is not
part
of that unlawful status such that reversion would undo a later admission.
The alien’s “unlawful status” is just his lack of permission to be present. There is no sub-category of unlawful status called “present without admission,” and the government’s protestation to the contrary is not backed by any citation to apt authority.
Past decisions and our review of the statutory scheme confirm this view. Our decisions and those of the BIA regularly distinguish among different types of lawful status
but not among various types of
unlawful status.
Nor does the statutory scheme discriminate among forms of unlawful status.
The INA refers to “immigrant status” and “nonimmigrant status,” as well as numerous sub-categories of each, thereby contrasting different types of lawful presence; instances of the term “unlawful status,” however, are limited to those bare words.
See Tula Rubio,
787 F.3d at 295 & n.6 (collecting examples).
The statute does describe “classes of deportable aliens,”
see
8 U.S.C. § 1227, and “classes of aliens ineligible for visas or admission,”
see id.
§ 1182, but neither
Tula Rubio
nor any other decision refers to or treats those grounds for deportability or inadmissibility as statuses. Further, the regulation treats unlawful status on the one hand, and excludability and deportability on the other, as distinct concepts. It operates to “return such alien to the unlawful status held prior to the adjustment,
and
render him or her amenable to exclusion or deportation proceedings under section 236 or 242 of the Act, as appropriate.” 8 C.F.R. § 245a.2(u)(4) (emphasis added).
If a ground for removability were equivalent to a specific form of unlawful status, the regulation would not have needed sep- ■ arately to specify those results.
The canon against surplusage thus supports our view that status does not encompass admission.
Moreover, as Gomez aptly points out, 8 U.S.C. § 1255, the adjustment-of-status statute, tracks the admission/status distinction. That section treats lack of admission and unlawful status as separate bars to adjustment of status, subject to different exceptions, and addressed in separate subsections. Section 1255(a) indicates that admission is in most cases a prerequisite to applying for adjustment of status. But an alien classified as a self-petitioner under the Violence Against Women Act need not have been admitted.
Id.
Unlawful status is treated in a different statutory subsection, § 1255(c)(2), which provides that an alien “who is in unlawful immigration status on the date of filing the application for adjustment of status” is ineligible for an adjustment. That rule is subject, however, to exceptions for immediate relatives of citizens and certain other special immigrants. The government’s conflation of admission and status would render redundant the separate articulation of those two grounds for ineligibility and would undo Congress’s careful calibration
of different exceptions for the two separate factors.
The government argues that
Heman-dez-Arias
supports its interpretation and that we should follow our sister court’s decision as persuasive authority. By its own terms, however, that ease is inappo-site.
Hernandez-Arias
involved a collateral challenge to a deportation as part of an appeal of a conviction; the defendant claimed he was not properly removable as charged. Like Gomez, he had been granted temporary status but never permanent status under the amnesty. Although he had never been inspected and admitted at a port of entry, he maintained that his adjustment to temporary status constituted an admission, so he was not removable as charged as an alien present without being admitted or paroled.
Hernandez-Arias,
757 F.3d at 880. The Ninth Circuit noted that, in certain circumstances, the concept of admission was not limited to the procedural event described earlier in our discussion.
Id.
Rather, in select circumstances, admission will be imputed or deemed by operation of law — for example, when an alien is accepted into the Family Unity Program or receives an adjustment to lawful permanent residence, he is deemed admitted by operation of law regardless of whether he was ever physically admitted at a port of entry.
Id.
The Ninth Circuit assumed, for the sake of argument, that adjustment to temporary resident status under the amnesty was among the circumstances in which an alien would be deemed admitted by operation of law.
Id.
at 881. Nonetheless it rejected the alien’s claim, reasoning that a deemed admission by operation of law resulting purely from an adjustment to temporary lawful status would expire upon the expiration of the status adjustment.
Id.
On the Ninth. Circuit’s reasoning, 8 C.F.R. § 245a.2(u)(4) meant that, upon 'expiration of temporary residency, the legal fiction of admission that was derived from the temporary-resident status was undone.
Hernandez-Arias,
757 F.3d at 881.
Gomez posits that
Hernandez-Arias
is distinguishable. He notes that the opinion, by its explicit terms, deals only with the narrow case of unusual circumstances under which a change in one’s status under the immigration laws is treated as a deemed admission by operation of law.
See id.
at 881 n.3. On Gomez’s account, the Ninth Circuit’s careful effort to confine its decision to those rare instances of admission by operation of law supports the idea that the regulation could not undo the effect of a factual port-of-entry admission. In other words, Gomez concedes that any fictional, deemed admission that occurred by operation of law when he was adjusted to temporary resident status was undone by the expiration of that status, but he reasons that that does not matter: He was legally entitled to be admitted, and was in fact admitted, during his temporary residency.
We agree.
Hernandez-Arias
has no application here, for the reason Gomez identifies: There is nothing in the opinion that supports ignoring the historical fact of a port-of-entry admission that occurred during the period of time when an alien was a temporary resident. The type of deemed admission at issue in
Hernandez-Arias
would logically expire at the termination of a temporary residency, because the only reason why courts sometimes treat certain changes of status as deemed admissions is to avoid the oddities that would accompany treating an alien accepted into Family Unity Program, or given lawful permanent resident status, as unadmitted (which would render him subject to removal and a
variety of other sanctions plainly incompatible with his status under those programs).
See id.
at 880. When an alien’s adjusted status expires, and he is no longer entitled to privileges inconsistent with non-admission, it no longer makes sense to imply, legally, a fictitious admission from the adjustment, because there are no longer any absurd results.
Thus, Hernandez-Arias’s holding makes good sense, but that decision establishes nothing at all regarding a
factual
admission that occurs during a period of time that the alien is legally entitled to exit and reenter the United States, and its logic does not encompass such an admission. And, as the government acknowledges, Gomez was entirely free to leave the country for short periods of time and could be “admitted” on his return.
Hernandez-Arias
is materially distinct, so we decline the government’s invitation to treat it as relevant, persuasive authority.
The BIA has observed precisely the distinction that we describe here and has reached results that that distinction suggests. The previous decisions involving 8 C.F.R. § 245a.2(u)(4) that the government relies on follow the fact pattern from
Hernandez-Arias,
not the fact pattern from
Castro Valdez
and the instant case. That is, the aliens relied only on the fictional, deemed admission resulting from their adjustment to temporary resident status, not a factual admission that took place during their temporary residency.
In the only BIA case cited by either party in which the alien relied on a factual admission at a port of entry, rather than the fictional admission that occurred when he adjusted to temporary resident status, the BIA held that that admission was not affected by Section 245a.2(u)(4).
See Castro Valdez,
2012 WL 3911586, at *3.
IV.
In summary, the language in 8 C.F.R. § 245a.2(u)(4) that provides for an alien to return to a previous unlawful
status
does not also undo a factual
admission
that occurred during the. time when he was in lawful status. That is because his unlawful status does not encompass his lack of admission. Upon expiration of his temporary resident status, Gomez returned to his previous unlawful status (that is, he lost his permission to be present in the United States). But that does not change the historical fact that he had been admitted.
Because Gomez was admitted, and the regulation does not undo that admission, the petition for review is GRANTED, and this matter is REMANDED for proceedings as needed. We express no view on what actions the BIA should take on remand.
