OPINION OF THE COURT
VAN ANTWERPEN, Circuit Judge.
Appellant Long Tong Kiam was convicted by a jury on November 3, 2004, of three counts of alien smuggling in violation of 8 U.S.C. § 1324(a)(2)(B)(iii). His conviction arose from his arrest at Philadelphia International Airport after bringing three Chinese nationals illegally into the country. On February 4, 2005, the District Court sentenced Kiam to five years imprisonment and two years of supervised release. This appeal stems from the District Court’s denial of Kiam’s motion to suppress a confession he gave to an Immigration and Customs Enforcement agent while being questioned at the airport. Kiam contends the confession was invalid under
Missouri v. Seibert,
542 U.S. 600, 124 S.Ct. 2601, 159 L.Ed.2d 643 (2004), because, although it was obtained after Miranda
warnings were given, Kiam had already given inculpatory statements to another agent without the benefit of
Miranda.
We disagree and will affirm the District Court’s denial of the motion to suppress.
I.
On April 27, 2004, Long Tong Kiam, a Singaporean citizen with a valid Singapore passport, arrived on a Frankfurt-Philadelphia flight at Philadelphia International Airport. He — along with three Chinese nationals who had been sitting together but apart from Kiam — was escorted by Customs and Border Protection inspectors to a secondary inspection area.
In the previous week, Customs and Border Protection agents had uncovered several alien smuggling schemes whose characteristics matched those of Kiam and the Chinese nationals. Each of the Chinese nationals on Kiam’s flight had presented Singaporean passports in Frankfurt, although they did not have passports with them in Philadelphia.
Kiam was first interrogated by Customs and Border Protection Senior Inspector
Daniel Roman for about twenty five minutes. During the interrogation, Inspector Roman suspected Kiam of lying regarding: (1) whether he had recently traveled to Thailand, Turkey, and Europe, as reflected by his passport; and (2) whether he knew the three Chinese nationals on the airplane who had been traveling together. After Inspector Roman confronted Kiam with discrepancies based upon his passport entries and statements by the Chinese nationals, Kiam admitted that he knew the aliens, and was “illegally helping] them enter this country.”
United States v. Kiam,
343 F.Supp.2d 398, 401 (E.D.Pa. 2004). Inspector Roman did not give Kiam
Miranda
warnings at any time during this interrogation.
Inspector Roman then contacted Immigration and Customs Enforcement, which dispatched Immigration and Customs Enforcement Special Agent Richard Kozak to the airport. Inspector Roman did not further question Kiam. Upon arrival, Agent Kozak called a Chinese interpreter who determined that Kiam spoke many languages; Kiam indicated that he wished to speak in English. Agent Kozak then administered
Miranda
warnings, both in English and through the interpreter. Kiam waived these rights and filled out an official waiver form. Over the next three hours Agent Kozak interrogated Kiam about the smuggling scheme, and eventually Kiam described the alleged scheme’s mastermind along with their past dealings and the current trip to America. Kiam then wrote down his confession and signed it with amendments. He was subsequently arrested.
Kiam was indicted by a federal grand jury on three counts of alien smuggling. In the District Court for the Eastern District of Pennsylvania, which had jurisdiction pursuant to 18 U.S.C. § 3231, Kiam sought to suppress the confession he had given to Agent Kozak on the ground that it was elicited through an unconstitutional two-round interrogation strategy which was designed to sidestep his
Miranda
protection. The District Court denied the motion to suppress on October 22, 2004, holding that while Inspector Roman should have given Kiam
Miranda
warnings during the first interrogation, any alleged taint from the
pre-Miranda
statement did not extend into the second, post
-Miranda
confession. On November 3, 2004, after the written confession was presented at trial along with the testimony of the three Chinese nationals Kiam allegedly smuggled into the country, Kiam was found guilty by a jury of all three counts of alien smuggling. On February 4, 2005, the District Court sentenced Kiam to 60 months imprisonment, a special assessment of $300, and 24 months of supervised release. Kiam now appeals the District Court’s denial of his motion to suppress. We have jurisdiction over the appeal pursuant to 28 U.S.C. § 1291.
II.
Our review of the District Court’s factual findings in a suppression hearing is for clear error.
United States v. Naranjo,
426 F.3d 221, 226 (3d Cir. 2005). Our review of legal rulings and mixed questions of law and fact is plenary.
Id.
III.
We will address both elements of the District Court’s decision not to suppress Kiam’s second statement. First, we conclude that the District Court erred in holding that Kiam was entitled to
Miranda
warnings before he made his inculpatory statements to Inspector Roman. Second, however, we agree with the District Court’s ultimate conclusion that regardless of whether the first statements were unwarned, these
pre-Miranda
statements did not taint the
post-Miranda
confession.
Accordingly, whether or not the first statements required
Miranda,
the District Court properly denied the motion to suppress the second confession.
A. Initial Interrogation
The District Court first held that Inspector Roman should have administered
Miranda
warnings during the initial interrogation because the questioning went beyond “routine” admissibility inquiries, and that the failure to do so might have rendered his second confession inadmissible.
Kiam,
343 F.Supp.2d at 406. The District Court found that both traditional triggering elements — custody and interrogation— were present.
Id.
at 403-04. The District Court acknowledged that customs officials
are
permitted to ask aliens stopped at the border questions without
Miranda
warnings.
Id.
at 406. However, the District Court concluded, the questions here went beyond merely “routine” immigration issues because Inspector Roman had a “particularized suspicion” that Kiam was involved in criminal conduct.
Id.
This was error. For the reasons set forth below, we hold that Kiam was not entitled to
Miranda
warnings until the criminal investigator was called in because,
inter alia,
Inspector Roman’s questions still had a bearing on Kiam’s admissibility.
As the Supreme Court has emphasized repeatedly, the inquiry in
Miranda
cases is not into the officer’s subjective intent, suspicion, or views.
Stansbury v. California,
511 U.S. 318, 324, 114 S.Ct. 1526, 128 L.Ed.2d 293 (1994) (per curiam) (“It is well settled, then, that a police officer’s subjective view that the individual under questioning is a suspect, if undisclosed, does not bear on the question whether the individual requires
Miranda
warnings”);
see also Moran v. Burbine,
475 U.S. 412, 423, 106 S.Ct. 1135, 89 L.Ed.2d 410 (1986) (“[T]he state of mind of the police is irrelevant----”);
Seibert,
124 S.Ct. at 2616 (O’Connor, J., dissenting) (“[T]he plurality correctly declines to focus its analysis on the subjective intent of the interrogating officer.”). Moreover, the District Court cited no positive authority in this Circuit or otherwise — nor did Kiam' — for the proposition that non-“routine” immigration questions implicate
Miranda
Instead, the District Court’s analysis involved cases, none of which come from this Court, which stated merely that “the fifth amendment guarantee against self-incrimination is not offended by routine questioning of those seeking entry to the United States.”
United States v. Moya,
74 F.3d 1117, 1119 (11th Cir.1996) (quoting
United States v. Lueck,
678 F.2d 895, 899 (11th Cir.1982)).
While it appears that other courts have repeatedly upheld the authority of immigration inspectors to question aliens without
Miranda,
they have done so by forcing the non-analogous immigration context into normal
Miranda
jurisprudence and thereby avoiding the issue we address today. The District Court ruled as it did partly because these other courts spoke in the negative — “routine” immigration questions were not held to require
Miranda,
but no situation presented non-“routine” questions.
We recognize the facially-appealing nature of differentiating between “routine” and non-“routine” questions. However, an inspection of Circuit cases that apply this delineation shows that courts have gone to great pains to label almost all questioning “routine.” In
Moya,
an immigration inspector asked an alien, in a secondary inspection area, pointed questions about past deportations after a computer system had previously confirmed the alien’s earlier deportation. As in the present case, the
Moya
inspector questioned the alien about the exact elements of a crime, yet the
Moya
court deemed this simply “routine.” 74 F.3d at 1119-20 (quoting older Eleventh and Fifth Circuit cases);
see also United States v. Bengivenga,
845 F.2d 593, 599 (5th Cir.1988) (en banc) (admitting statements obtained through
pre-Miranda
questioning even after border agents’ “activity shifted from a routine checkpoint stop aimed at detecting illegal aliens to an investigation of drug smuggling”).
The Seventh Circuit confronted a situation virtually identical to the case at-hand in
United States v. Gupta,
183 F.3d 615 (7th Cir.1999). A suspected alien smuggler in secondary inspection admitted the smuggling scheme and signed a confession after receiving
Miranda
warnings from newly-arrived criminal investigators. Writing for the
Gupta
court, Judge Easterbrook refused to decide where the “routine questions asked of travelers at the border” ended in that case, because the
-post-Miranda
statements were admissible under
Oregon v. Elstad
regardless.
Gupta,
183 F.3d at 618.
We now reaffirm the well-established authority of border inspectors to ask questions of those entering the United States.
See, e.g.,
8 U.S.C. § 1225(b);
Gupta,
183 F.3d at 617;
United States v. Fernandez-Ventura,
132 F.3d 844, 846-47 (1st Cir.1998);
Moya,
74 F.3d at 1119-20;
United States v. Layne,
973 F.2d 1417, 1420-21 (8th Cir.1992);
Bengivenga,
845 F.2d at 598.
“A person seeking entry into the United States does
not
have a right to remain silent.”
Gupta,
183 F.3d at 617. An alien at the border of our country— even if that border is the Philadelphia International Airport, as here — must convince a border inspector of his or her admissibility to the country by affirmative evidence.
See, e.g.,
8 C.F.R. § 235.1(d)(1) (“Each alien seeking admission ... must establish to the satisfaction of the inspecting officer that the alien is ... entitled, under all of the applicable provisions of the immigration laws and this chapter, to enter the United States.”). While an alien is unquestionably in “custody” until he is admitted to the country, normal
Miranda
rules simply cannot apply to this unique situation at the border.
See Gupta,
183 F.3d at 617-18
{“Miranda
therefore is a mismatch for the immigration process, at least at the outset.... [PJersons seeking entry at the border may be questioned without
Miranda
warnings, even though they are also subject to custody....”). This is a situation utterly unlike a normal law enforcement setting. The alien may be taken out of a primary inspection line for secondary questioning, or as here, re
moved from a plane before reaching that initial line. Contrary to Kiam’s assertions, there is no functional difference between the preceding situations.
See Fernandez-Ventura,
132 F.3d at 847 (“[W]e fail to see how going directly to secondary inspection [and skipping primary inspection] makes the questioning more coercive.”). In either event, the alien still must meet his information production burden, and the border inspector is accordingly entitled to ask questions and require answers.
We will not impose an across-the-board rule requiring border inspectors to immediately cut off their questioning if they think they may be going beyond what could be considered “routine” immigration questioning. Nor will we extend
Miranda
beyond the holdings of our sister Circuits and hold that if a customs official subjectively suspects criminal conduct in addition to inadmissibility, he must Mirandize the alien before questioning him on any subject. Not only would such a rule conflict with
Stansbury
and other
Miranda
jurisprudence, but it would also run afoul of the need for clear rules in the
Miranda
context.
See, e.g., Berkemer v. McCarty,
468 U.S. 420, 430, 104 S.Ct. 3138, 82 L.Ed.2d 317 (1984).
The Seventh Circuit has stated that eventually, a “line must be drawn,” beyond which
Miranda
warnings are required.
Gupta,
183 F.3d at 618. We see only one line to draw—at some point, as was the case here and in
Gupta,
a Customs and Border Protection inspector will have sufficient information to make a determination regarding admissibility and will then decide whether to call in a criminal investigator such as Immigration and Customs Enforcement Agent Kozak.
Miranda
may then apply.
Accord Gupta,
183 F.3d at 618 (citing as a possible demarcation the “arrival of criminal investigators”). If the inspector’s questions objectively cease to have a bearing on the grounds for admissibility and instead only further a potential criminal prosecution, however, this line has been crossed.
Before this point, there is not likely to be the “restraint on freedom of movement of the degree associated with a formal arrest” in normal immigration practice, where questioning and delay is the norm.
California v. Beheler,
463 U.S. 1121, 1125, 103 S.Ct. 3517, 77 L.Ed.2d 1275 (1983) (per curiam) (quoting
Oregon v. Mathiason,
429 U.S. 492, 495, 97 S.Ct. 711, 50 L.Ed.2d 714 (1977)). This is the only possible “line” which sufficiently reflects the deference due inspectors at the border of the United States. We decline the urging of Kiam to require
Miranda
warnings as soon as an alien is taken off a plane or sent for secondary inspection.
While appealing on the surface, we note the impossibility of the District Court’s “particularized suspicion” test. An alien reentering the country after being
deported is guilty of a criminal offense. 8 U.S.C. § 1326. Aliens applying for admission at the border are routinely run through a system to check their immigration history. A positive match to a previously-deported alien would lead to secondary inspection, and would surely create a “particularized suspicion” in the mind of any immigration inspector that this alien was guilty of a crime. The criminal offense of illegal reentry is inextricably tied up with the alien’s current admissibility, yet by the District Court’s reasoning, an immigration inspector would first have to administer
Miranda
warnings before questioning the alien about that admissibility.
Cf. Moya,
74 F.3d at 1119 (permitting an immigration inspector to question an alien, without
Miranda
warnings, after an INS system indicated that the alien had previously been deported, and was therefore attempting to illegally reenter the country).
Here, the record shows that Kiam was determined to be administratively inadmissible because of the same conduct which formed the basis for his criminal indictment — alien smuggling. 8 U.S.C. § 1182(a) (6) (E) (i). Suspicion of criminal conduct cannot overrule the simultaneous responsibility of immigration or customs agents to inspect entrants at our borders.
See United States v. Silva,
715 F.2d 43, 48 (2d Cir.1983) (holding that regardless of whether an immigrations inspector had probable cause to arrest for a criminal violation, a customs officer remained “duty-bound to determine whether Silva was entitled to enter the country with her effects” and
Miranda
warnings were not required).
We do not disagree with the holdings of any of our sister Circuits, who have as a functional matter upheld almost all pr
e-Miranda
questioning during border detentions. Attempting to force these cases into the rubric of “routine” questioning, however, ignores the very real issues of border immigration practice.
Here, Kiam was not entitled to
Miranda
warnings before he made his first incriminating statements to Inspector Roman. At the point at which Inspector Roman ceased questioning about administrative admissibility and called in a criminal investigator, however,
Miranda
was implicated — and such warnings were indeed given at this proper time by Agent Kozak. It was error for the District Court to conclude that
Miranda
warnings were needed before Inspector Roman could question Kiam. However, as we explain below, the second statement is clearly admissible regardless.
B. Two-Stage Interrogation Under
Elstad
and
Seibert
We do not agree with the District Court that under the facts before us Kiam should have been given
Miranda
warnings while speaking with Inspector Roman. As such, Kiam’s statement to Agent Kozak, which was taken after
Miranda
warnings were given, is admissible. We write further to briefly clarify the proper analysis to follow had the District Court been correct, and the first statement actually been improperly unwarned. Under this analysis, the District Court was correct that Kiam’s
post-Miranda
confession to Agent Kozak was admissible regardless.
The Supreme Court addressed this issue first in
Oregon v. Elstad,
470 U.S. 298, 314, 105 S.Ct. 1285, 84 L.Ed.2d 222 (1985), in which the Court held that “absent coercion or improper tactics in obtaining the initial statement,” a post
-Miranda
statement would not be automatically excluded because of an earlier, pr
e-Miranda
confession.
The Court instructed lower courts
to “examine the surrounding circumstances and the entire course of police conduct with respect to the suspect in evaluating the vohmtariness of his [initial] statements.”
Elstad,
470 U.S. at 318, 105 S.Ct. 1285. Where no coercion is found, “a careful and thorough administration of
Miranda
warnings cures the condition that rendered the unwarned statement inadmissible.”
Reinert v. Larkins,
379 F.3d 76, 90 (3d Cir.2004) (citing
Elstad,
470 U.S. at 311-12, 105 S.Ct. 1285).
The Supreme Court recently revisited this issue in
Missouri v. Seibert,
542 U.S. 600, 124 S.Ct. 2601, 159 L.Ed.2d 643 (2004). A four-member plurality held that courts should apply a five-factor test
to determine the admissibility of a second confession given after a
pre-Miranda
statement.
Seibert
involved an official, wide-spread police protocol which directed officers to interrogate suspects extensively without
Miranda
warnings, obtain a confession — which the officers knew could not be used in court — then adjourn briefly, return and give the suspect his
Miranda
rights, and re-elicit a now-valid confession.
Justice Kennedy, supplying the fifth vote to exclude the confession at issue, narrowed the test to two parts. First, a court must decide whether the officers made a “deliberate” choice to flout
Miranda
in the first round of interrogation.
Seibert,
124 S.Ct. at 2616 (Kennedy, J., concurring). If so, the second confession could still be admitted if “curative” measures were taken — for example, a sufficient break in time or circumstances between interrogations, or a warning to the suspect that the first statement could not be used against him.
Id.
If the failure to give
Miranda
warnings was
inadvertent,
however, Justice Kennedy stated that “[t]he admissibility of postwarning statements should continue to be governed by the principles of
Elstad.” Seibert,
124 S.Ct. at 2616 (Kennedy, J., concurring).
This Court applies the
Seibert
plurality opinion as narrowed by Justice Kennedy.
Naranjo,
426 F.3d at 231-32 (citing
Marks v. United States,
430 U.S. 188, 193, 97 S.Ct. 990, 51 L.Ed.2d 260 (1977)).
The first question under
Seibert
is whether Inspector Roman deliberately used a two-step interrogation process. The District Court concluded that there had been no deliberate attempt to sidestep
Miranda,
and Kiam does not contest the holding on appeal.
Once we determine that the
Miranda
violation was not deliberate, we must fall back on
Elstad
as instructed by Justice Kennedy. The District Court appears to have implicitly concluded that Kiam’s claim failed under
Elstad,
and then in the name of thoroughness proceeded to show that Kiam’s claim would also fail under the five
Seibert
plurality factors.
Kiam,
343 F.Supp.2d at 409-11. The District Court’s
analysis of the five
Seibert
factors was not faulty, but it was unnecessary, having found the initial failure to give
Miranda
warnings inadvertent. The District Court should have proceeded solely under
Elstad.
Applying the traditional
Elstad
test, we conclude that Kiam’s confession to Agent Kozak was not “tainted” by the first, preMiranda statement in such a way as to require its suppression. First, there was no evidence of coercion or improper tactics in Inspector Roman’s questioning of Kiam.
See also United States v. Ventura,
85 F.3d 708, 711 (1st Cir.1996) (“[Questions from officials are especially understood to be a necessary and important routine for travelers arriving at American entry points. This understanding cuts against the potentially coercive aspect of the Customs inquiry, and lessens the need for
Miranda
warnings.”).
Second, Agent Kozak gave “a careful and thorough administration of
Miranda
warnings.”
Reinert,
379 F.3d at 90. The District Court found that upon meeting Kiam and obtaining an interpreter by phone:
“Kozak gave Kiam
Miranda
warnings. Despite Kiam’s English preference, Wong [the interpreter] methodically ensured that Kiam understood each sentence of the warnings. For instance, after Kozak read aloud each sentence, Wong asked Kiam in Mandarin whether he understood, providing additional explanation when necessary. When Kozak finished explaining these rights at 5:18 p.m., Kiam waived them, memorializing this on an ICE 1-214 form.”
Kiam,
343 F.Supp.2d at 402. There was no clear error in these findings.
See Elstad,
470 U.S. at 318, 105 S.Ct. 1285 (“The relevant inquiry is whether, in fact, the second statement was also voluntarily made.”). Had a
Seibert
or
Elstad
analysis been ultimately necessary here, we “conclude that the cure mandated by
Elstad
was met in this 'case, and that because [Kiam’s] waiver was knowing and voluntary, the
post-Miranda
statement was properly entered into evidence.”
Reinert,
379 F.3d at 91.
IV.
For the foregoing reasons, we conclude that the District Court properly refused to suppress Kiam’s statement to Agent Kozak. Accordingly, the judgment of the District Court will be affirmed.
