OPINION OF THE COURT
I. FACTUAL AND PROCEDURAL HISTORY
This matter comes on before this court on Rolando Sierra’s appeal from an order entered in the district court on June 18, 2002, denying his petition for a writ of habeas corpus. 1 Sierra is a 41-year-old Cuban national who arrived in the United States in 1980 as part of the Mariel boatlift during which over 125,000 Cubans crossed by boat from Mariel harbor in Cuba to the United States. 2 See JA 7. Immigration officials stopped Sierra and most Mariel Cubans at the border as they were “ex-cludable” under the then effective immigration law. 3 Although excludable aliens such as Sierra have not “entered” the country for the purposes of immigration law, the government nevertheless permitted him as well as other Mariel Cubans to make a physical entry into the United States pursuant to the Attorney General’s authority under 8 U.S.C. § 1182(d)(5)(A) *562 to grant immigration parole. 4
Following Sierra’s physical entry into the United States he engaged in a series of serious criminal acts in this country. Thus, he was convicted, inter alia, of carrying a deadly weapon and of theft in the District of Columbia in 1986 and of daytime housebreaking and of theft in Maryland in 1990 and 1991. 5 JA 7. As a result of these convictions, the Immigration and Naturalization Service (“INS”) quite naturally and appropriately revoked Sierra’s immigration parole. See JA 7. On January 6, 1992, after denying Sierra’s applications for asylum and withholding of deportation, an immigration judge ordered that he be excluded and deported from the United States. JA 49-50. Sierra appealed the decision of the immigration judge to the Board of Immigration Appeals which summarily dismissed the appeal on May 6, 1992. JA 52.
Sierra should have been deported immediately but unfortunately the Cuban government generally has refused to cooperate in the return of Mariel Cubans and specifically has declined to receive Sierra. See JA 102. The INS therefore has held Sierra in custody for most of the last 11 years detaining him in various federal penitentiaries operated by the Bureau of Prisons, including the facility at Lewisburg, Pennsylvania, at the time he brought this action, and currently the facility at Lom-poc, California.
Since his detention and throughout the time Sierra has been in INS custody, the INS annually has reconsidered releasing him on immigration parole in accordance with 8 C.F.R. § 212.12 (2003), which governs the cases of Mariel Cubans who remain in the Attorney General’s custody. Pursuant to these regulations, a Cuban Review Panel makes a recommendation to the INS Associate Commissioner for Enforcement,
6
who has the discretion to approve parole.
Sierra v. INS,
On July 28,1998, a Cuban Review Panel recommended Sierra’s parole to a halfway house, noting that he had not been in *563 volved in any disciplinary incidents in 1998. Id. That decision, however, was revoked due to Sierra’s involvement in a fight. JA 8. A panel conducted an interview on March 18, 1999, following which it declined to recommend parole, finding that Sierra was “violent and [would] remain violent if released.” Id. Though a Cuban Review Panel interviewed Sierra again on September 13, 2000, and recommended him for parole, this recommendation was withdrawn on May 13, 2002, after Sierra was disciplined for disruptive behavior in October 2001. See JA 157.
Prior to filing his current petition for a writ of habeas corpus, Sierra had filed several other petitions seeking habeas relief. While he was incarcerated in Florence, Colorado, he filed an action in the United States District Court for the District of Colorado, challenging the Cuban Review Panel’s 1998 withdrawal of parole based on the fighting incident.
See
JA 9. The district court, however, dismissed the action by an order dated August 9, 1999, and in August 2001, the Court of Appeals for the Tenth Circuit affirmed the district court’s order.
Sierra,
Sierra filed the present petition for a writ of habeas corpus on May 15, 2000, in the Middle District of Pennsylvania.
See
JA 6. In his petition Sierra maintained that the INS improperly denied him visits with his family and improperly denied him parole.
See
JA 9. In proceedings before the district court Sierra argued that he was being detained in violation of the Fifth and Sixth Amendments of the Constitution, contentions he has abandoned,
8
and that the Supreme Court’s then recent decision in
Zadvydas v. Davis,
II. DISCUSSION
A. Jurisdiction and Standard of Review
The district court had jurisdiction under 28 U.S.C. § 2241 and we have jurisdiction under 28 U.S.C. §§ 1291 and 2253. We exercise plenary review over the district court’s legal conclusions and ordinarily would review its findings of fact under a clearly erroneous standard.
See Ruggiano v. Reish,
B. The Statutory Basis for Sierra’s Current Detention
The parties dispute the statutory authority for Sierra’s current detention. 9 Sierra argues that “8 U.S.C. § 1231(a)(6) is the statute authorizing [his] current imprisonment.” Br. of appellant at 14. The government maintains that former 8 U.S.C. §§ 1226(e), 1225(b), 1227(a) and 1182(d)(5)(A) (1994) and not current section 1231(a)(6) govern his detention. Br. of appellee at 20.
Congress enacted 8 U.S.C. § 1231(a)(6) (hereinafter “section 1231(a)(6)”) as part of the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (“IIRIRA”), Pub.L. No. 104-208, 110 Stat. 3009 (Sept. 30, 1996). Although IIRIRA had a general effective date of April 1, 1997, see IIRIRA § 309(a) (codified at 8 U.S.C. § 1101 note (2000)), a transition section specifies that certain of its provisions do not apply “in the case of an alien who is in exclusion or deportation proceedings before [April 1, 1997].” Id. § 309(c)(1) (hereinafter “section 309(c)(1)”). 10 According to the government, section 309(c)(1) of IIRIRA precludes this court from applying IIRIRA to Sierra, an unadmitted, inadmissible alien ordered excluded and deported prior to its effective date.
In contrast Sierra contends that IIRIRA does apply and that section 1231(a)(6) governs this action because: (1) the most natural reading of section 309(c)(1) is that it applies only to matters at issue through the pendency of proceedings and not to post-final-order detention determinations; (2) in Zadvydas the Supreme Court applied section 1231(a)(6) to a petitioner who had been placed in deportation proeeed- *565 ings and ordered deported prior to April 1, 1997; and (3) in Zadvydas, as well as in other eases, the INS has argued that section 309(c)(1) only applies to aliens in pending deportation or exclusion proceedings, not to post-final-order detention determinations.
As we will discuss in more detail below, several courts of appeals have found that section 1231(a)(6) governs the detention of aliens in procedural circumstances similar to those of Sierra.
11
See Martinez-Vazquez v. INS,
(a) The language of section 309(c)(1)
IIRIRA’s transition provision, section 309(c)(1), surely is ambiguous. Uncertainty arises from its present tense language describing an alien who “is” in proceedings “before” April 1, 1997. As the Court of Appeals for the Fifth Circuit stated in
Zadvydas v. Underdown,
“[t]he problem is created by the statute’s usage of ‘before,’ which might be read to imply that the statute only affects those that were free of any involvement in deportation [or exclusion] proceedings prior to the effective date.”
As originally enacted, the transition rule in section 309(c)(1) applied “in the case of an alien who is in exclusion or deportation proceedings as of [April 1, 1997].” (Emphasis added.)
12
But 11 days after IIRI-RA’s enactment, a technical amendment struck and replaced the term “as of’ with the term “before.”
See
Extension of Stay in the United States for Nurses Act, Pub.L. No. 104-302, § 2, 110 Stat. 3656 (1996). The government argues that this technical amendment “made clear that IIRIRA’s provisions do not apply to aliens who were placed in administrative proceedings
before
IIRIRA’s general effective date of April 1, 1997.”
See
Br. of appellee at 24. It is not clear, however, that Congress intended the amendment to have that broad effect, though we acknowledge that if Congress had not substituted “before” for “as of’ it would be clearer that section 1231(a)(6) would apply in cases such as this one completed before IIRI-RA’s effective date. As the Court of Appeals for the Fifth Circuit explained in
Zadvydas v. Underdown,
“[t]he confusing ‘before’ was ... the product of what was labeled as a ‘technical’ amendment established by the Hatch-Kennedy amendment to the H-1A Nursing Bill.... Nothing indicates what the goal of this amendment was, and the failure of the amendment to change the surrounding language makes
*566
its intended purpose unclear.”
The Court of Appeals for the Sixth Circuit’s en banc decision in
Rosales-Garcia
and the Court of Appeals for the Fifth Circuit’s decision in
Zadvydas v. Under-down
support Sierra’s position that section 309(c)(1) applies only to matters relating to ongoing deportation or exclusion proceedings and not to post-final-order detention determinations so that section 1231(a)(6) is applicable in this case.
13
Rosales-Garcia
involved Mariel Cubans who, like Sierra, were unadmitted aliens ordered excluded and deported before IIRIRA’s effective date. The court of appeals found that the present tense language of section 309(c)(1) and the Supreme Court’s language in
INS v. St. Cyr,
In support of his argument that IIRIRA applies unless the immigrant in question was in pending immigration proceedings on April 1, 1997, Sierra also points to
St. Cyr
in which the Supreme Court noted that “[s]ection 309(c)(1) is best read as merely setting out the
procedural
rules to be applied to removal proceedings pending on the effective date of the statute.”
*567 Section 309(c)(1)(B), which provides that “the proceedings (including judicial review thereof) shall continue to be conducted without regard to such amendments,” i.e., under pre-IIRIRA law, also supports this interpretation of section 309(c)(1). As amicus American Civil Liberties Union (“ACLU”) points out, the focus on “proceedings” and “judicial review thereof’ in section 309(c)(1)(B) confirms that section 309(c)(1) governs issues relating to the determination of excludability or deportability, not post-final-order detention that occurs thereafter and is unrelated entirely to the proceedings. See Br. of amicus at 12-13.
(b) INS’s shifting position on the applicable law
In its brief the government argues that “the INS has consistently taken the position that, pursuant to section 309(c)(1) of IIRIRA, the pre-IIRIRA law applies to the detention of excludable aliens whose immigration proceedings were initiated prior to April 1, 1997.” Br. of appellee at 27. In addition, according to the government, “to the extent this Court finds IIRI-RA § 309(c) ambiguous, it should accord Chevron 16 deference to the INS’s interpretation.” Br. of appellee at 28.
Contrary to the government’s contention that it “consistently [has] taken the position that, pursuant to § 309(c)(1) of IIRI-RA, the pre-IIRIRA law applies to the detention of
excludable
aliens whose immigration proceedings were initiated prior to April 1, 1997,” the government previously has argued that IIRIRA, not pre-IIRIRA law, applies to the detention of excludable aliens whose immigration proceedings were initiated and
concluded
prior to April 1, 1997. Most significantly, in Sierra’s pri- or litigation challenging the parole revocation process, the government acknowledged before the Court of Appeals for the Tenth Circuit that IIRIRA applied.
See Sierra,
In addition, the INS has argued in cases involving deportable aliens that section 309(c)(1) applies only when proceedings are in progress. The government advanced this exact reason before the court of appeals in
Zadvydas v. Underdown
to justify application of section 1231(a)(6) to the petitioner, who had been placed in proceedings prior to April 1, 1997. In that case the government argued that the “exception in section 309(c)(1) ... only applies to ‘proceedings’ in progress. Because Mr. Zadvydas already has a final deportation order and his administrative proceedings have been concluded, the exception found in 309(c)(1) does not apply to his case, and the effective date provision of § 309(a) governs.”
17
See
Respondents-Appellants’
*568
Supplemental Brief in
Zadvydas v. Underdown,
As the ACLU also points out, following the Supreme Court’s decision in Zadvydas the government continued to advance the same interpretation of section 309(c)(1) to justify application of section 1231(a)(6) to an alien placed in deportation proceedings prior to IIRIRA’s effective date and ordered deported thereafter. See Br. of amicus at 16. The government argued before the Court of Appeals for the Eleventh Circuit that section 309(c)(1) did not govern the alien’s detention because he was subject to a final order and no longer was in deportation “proceedings.” See Brief for respondent/appellees in Al Najjar v. Ashcroft at 13-14, No. 02-11153-JJ (11th Cir.) (filed May 21, 2002) (copy attached to amicus brief as Exh. B). In further support of its position, the government argued that Congress intended that the same detention rules would apply to individuals subject to final orders regardless of the date of those orders, stressing that: “[Bjecause custody decisions are necessarily prospective, it is logical that Congress intended one set of detention rules to apply to all aliens with final orders awaiting deportation or removal.” 18 Id. at 14. Though the procedural posture of Al Najjar differs from that here inasmuch as in that case the deportation order was entered after IIRIRA’s effective date, the government’s position in Al Naijar is somewhat inconsistent with its position here.
Notwithstanding its position in these cases, the government recently has abandoned this interpretation of section 309(c)(1) and now contends that IIRIRA has a more limited application. Thus, before the Court of Appeals for the Sixth Circuit in
Rosales-Garcia,
the government argued that section 309(c)(1) precludes application of section 1231(a)(6) in all cases of aliens excluded prior to IIRIRA’s effective date.
See
*569 We do not suggest that a governmental agency may not change its interpretation of a statute and, indeed, we recognize that ordinarily it should make such a change if it believes that its prior interpretation was incorrect. Thus, we have no intention of discouraging agencies from reevaluating their positions regarding the meaning of statutes.
Nevertheless an agency’s interpretation is entitled to deference in accordance with the “thoroughness evident in [the agency’s] consideration, the validity of its reasoning, its consistency with earlier and later pronouncements, and all those factors which give it power to persuade, if lacking power to control.”
EEOC v. Arabian Am. Oil Co.,
In conclusion, because the best interpretation of section 309(c)(1) as adopted by several courts of appeals is that IIRIRA applies unless the petitioner was in deportation proceedings pending on April 1, 1997, we will interpret IIRIRA that way. In the circumstances, inasmuch as Sierra’s proceedings were concluded in 1992 and therefore no longer were pending on April 1, 1997, section 1231(a)(6) governs his current detention and we will apply that statute here.
C. Construction of Section 1231(a)(6) as Applied to Sierra
In view of our conclusion that section 1231(a)(6) governs Sierra’s detention, 22 we *570 must determine whether the Supreme Court’s holding in Zadvydas, reading into section 1231(a)(6) a temporal limit on post-removal detention for resident aliens, also applies to the detention of an unadmitted, inadmissible alien such as Sierra. The district court held that Zadvydas was not applicable because, unlike the petitioners in Zadvydas, Sierra “never effectuated an entry into the United States.” JA 12. Sierra argues that the district court’s “opinion reflects an incorrect reading of Zadvydas, which construed the statute which authorizes imprisonment of all immigrants pending deportation, whether or not they have affected a legal entry into the United States.” Br. of appellant at 6. Sierra claims that the district court erred, “because it is well-established that a statutory interpretation rendered by the Supreme Court, even on the basis of the Constitutional avoidance doctrine, is binding in all applications of the statute.” Br. of appellant at 10.
(a) Section 1231(a)(6)
After an alien, such as Sierra, is ordered removed from the United States, the Attorney General must attempt to secure his removal within 90 days. See 8 U.S.C. § 1231(a)(1) (the “removal period”). Moreover, “[u]nder no circumstance during the removal period shall the Attorney General release an alien who has been found inadmissible.... ” 8 U.S.C. § 1231(a)(2). Congress, however, recognizes that securing an alien’s actual removal within 90 days is not always possible. Consequently section 1231(a)(6) authorizes the Attorney General to detain aliens beyond the 90-day removal period, as it provides:
An alien ordered removed who is inadmissible under section 1182 of this title, removable [for violations of non-immigrant status or entry conditions, violations of criminal laws, or threats to national security] or who has been determined by the Attorney General to be a risk to the community or unlikely to comply with the order of removal, may be detained beyond the removal period and, if released, shall be subject to the terms of supervision in paragraph (3).
The INS has detained Sierra because his conduct shows that he is a risk to the community.
(b) Zadvydas v. Davis
In Zadvydas the Supreme Court considered whether the government’s authority under section 1231(a)(6) to detain two legal permanent residents beyond the 90-day removal period allowed it to detain them indefinitely. There two legal permanent residents were ordered removed by reason of their criminal convictions. The government, however, could not remove them because no country would accept them.
In evaluating the legality of indefinite detention in
Zadvydas,
the Supreme Court considered whether indefinite detention of resident aliens, if authorized by section 1231(a)(6) as the government contended was the case, would present constitutional problems. In making its determination the Court predicated its decision on its recognition that the two resident alien pe
*571
titioners in
Zadvydas
enjoyed certain constitutional privileges associated with individuals who have gained entry into the United States.
In
Zadvydas
the Court further stressed that “[t]he distinction between an alien who has effected an entry into the United States and one who has never entered runs throughout immigration law.”
Id.
at 693,
After an extended discussion of the serious constitutional problems of permitting the indefinite detention of legal permanent residents as opposed to unadmitted aliens, the Court in
Zadvydas
saved section 1231(a)(6) from possible unconstitutionality in the context of a resident alien by limiting the post-removal-period detention to a length of time reasonably necessary to bring about the actual removal of the resident alien.
Id.
at 694-99,
(c) Courts of Appeals split post-Zadvy-das
There is a division of opinion among the courts of appeals as to whether
Zadvydas
limits only the government’s authority to detain resident aliens or whether it applies to all categories of aliens.
Compare Borrero v. Aljets,
Inasmuch as the Supreme Court has not resolved the issue we are constrained to reach a conclusion on the question of whether in the light of
Zadvydas
the government may detain an unadmitted alien indefinitely under section 1231(a)(6) if it is unable to send the alien to any other country. In this process we first will discuss why Sierra remains an inadmissible alien and then examine whether the reasonableness component, as read into section 1231(a)(6) by the Supreme Court in
Zadvy-das,
applies to inadmissible aliens.
See Benitez,
(d) Sierra is an unadmitted alien
Although Sierra has been present physically in the United States for more than 20 years, the government never formally has admitted him and inasmuch as he was excludable when he arrived he is, as we explained above, an inadmissible alien.
See supra
note 3 and accompanying text. We reiterate that when Sierra arrived in the United States as part of the Mariel boatlift he was stopped at the border and paroled into this country. He was paroled because Congress has recognized that it is often appropriate to permit arriving aliens, such as Sierra, to make a temporary, unofficial entry into the United States pending the resolution of their applications.
See Benitez,
Any discussion of Sierra’s rights in the immigration context also must recognize the fundamental difference in the legal status of (1) unadmitted aliens such as Sierra and (2) resident aliens who have effected “entry” into the United States, whether illegally or legally.
See id. Zad-vydas
recognized this critical distinction which has been a hallmark of immigration law for more than a hundred years.
Id.
For example, in
Leng May Ma
the Supreme Court emphasized that “our immigration laws have long made a distinction
*573
between those aliens who have come to our shores seeking admission ... and those who are within the United States after an entry, irrespective of its legality.”
(e) Zadvydas’s temporal limitation on detention does not apply to Sierra
Although Sierra does not argue that he has a constitutional right precluding his continued detention, he does argue that he has a statutory right under section 1231(a)(6),
'post-Zadvydas,
prohibiting indefinite detention.
25
See
Br. of appellant at 17. We reiterate that there is a split of opinion among the courts of appeals regarding the breadth of Zadvydas’s holding. The Courts of Appeals for the Sixth and Ninth Circuits have held that
Zadvy-das
applies to all aliens regardless of their legal status.
See Rosales-Garcia,
The Courts of Appeals for the Eighth and Eleventh Circuits have addressed in some detail the issue of whether the
Zadvydas
Court’s construction of section 1231(a)(6) as containing a “reasonableness” component must apply categorically to all aliens, regardless of the aliens’ legal status.
Borrero,
First, in
Borrero
the court explained that
Zadvydas
limited “the detention only of those aliens whose detention raises serious constitutional doubt - admitted aliens.”
Borrero,
In
Benitez
the court of appeals stated that it found the
Borrero
court’s reasoning persuasive and therefore adopted it.
See Benitez,
Second, the court of appeals in
Benitez,
adopting the reasoning of the dissent in
Xi,
stated that it takes “the Supreme Court at its word: while indefinite detention raises serious constitutional questions in the case of aliens who have been admitted to the United States, ‘[a]liens who have not yet gained initial admission to this country would present a very different question.’ ”
Id.
(quoting
Xi,
Third, as the
Benitez
court explained, the ability to exclude aliens from this country at its borders is a duty entrusted to the Executive Branch so that it may protect the citizens and residents of this country from all manner of nameless dangers.
See id.
at 1300. In
Zadvydas,
the Supreme Court emphasized that the eases before it did not require it to consider the political branches’ authority to control entry into the United States and therefore the court was not leaving an “unprotected spot in the Nation’s armor.”
Zadvydas,
Fourth, the court of appeals in Benitez reiterated that “Congress has given the Attorney General the discretion to detain or parole persons who are not admitted into this country and whose own country will not take them back.” Id. In light of the fact that the Supreme Court in Zadvy-das went to such great lengths to distin *576 guish inadmissible aliens from aliens who have gained entry, courts should not fetter that discretion by presumptively requiring their release into this country after six months. Id.
Fifth and finally, in
Benitez
the court of appeals stated that “reading § 1231(a)(6) as creating a right to parole into this country after six months for inadmissible aliens is undoubtedly a drastic expansion of the rights of inadmissible aliens, who have never gained entry into this country.”
Id.
Moreover, as the
Benitez
court indicated, “[i]t is without question that Congress had a contrary intention when enacting IIRI-RA: it sought to tighten immigration regulations. As the very language of IIRIRA mandates, courts are not to construe IIRI-RA to ‘create any substantive or procedural right or benefit that is legally enforceable.’ 8 U.S.C. § 1231(h).”
Benitez,
The Benitez court further explained that inadmissible aliens who never have been admitted into the United States never truly have resided in this country free from restraint. See id. at 1301. “Rather, Congress has bestowed on them the luxury of parole while their immigration applications and status are finalized. To pervert this gift from Congress into a right after six months not only would distort Congress’s intent and potentially create grave security concerns for the people of the United States, but also would create needless difficulties in how the INS processes aliens.” Id.
We have considered the precedents on both sides of the Zadvydas issue and have made an independent analysis of the parties’ arguments with respect to the case’s application. From these examinations we have concluded that inasmuch as Zadvy-das’ s holding is qualified in so many regards, and there is no need to construe section 1231(a)(6) to avoid constitutional due process concerns for inadmissible aliens who never have been admitted into the United States, the Attorney General has the authority under section 1231(a)(6) to detain Sierra indefinitely and Zadvydas’ s six-month presumption of reasonableness is not applicable to him. Accordingly, the district court properly denied his petition for a writ of habeas corpus.
III. CONCLUSION
In summary, we agree with the courts of appeals that have held section 1231(a)(6) is applicable in cases in procedural postures similar to this case but we hold that Sierra is not entitled to relief under that section as it permits his indefinite detention. Accordingly, we will affirm the orders of May 17, 2002, and June 18, 2002, denying his petition for a writ of habeas corpus.
Notes
. Sierra filed his petition for habeas corpus in the district court under 28 U.S.C. § 2241.
See
JA 22. In
INS v. St. Cyr,
. Sierra had been incarcerated in Cuba for petty theft immediately preceding his departure to the United States. See JA 74.
. The Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (IIRIRA) substantially altered the landscape in immigration law and brought about a shift in basic immigration terminology.
Chi Thon Ngo v. INS,
. 8 U.S.C. § 1182(d)(5)(A) stipulates that "such parole of such alien shall not be regarded as an admission of the alien.”
Rosales-Garcia v. Holland,
. Sierra's convictions for theft and breaking and entering are aggravated felonies under the Immigration and Nationality Act. See 8 U.S.C. § 1101(a)(43).
.In order to recommend that a detainee be paroled, the panel members, two members of the INS professional staff, must conclude that the detainee is presently non-violent, likely to remain non-violent, and not otherwise likely to violate any conditions in the event of his parole.
Chavez-Rivas v. Olsen,
. The district court adopted the findings and conclusions of a magistrate judge who recommended that the court dismiss Sierra's petition for lack of jurisdiction pursuant to section 242(g) of the Immigration and Nationality Act, 8 U.S.C. § 1252(g), because "[djetention of aliens pending repatriation constitutes an ‘action by the Attorney General’ incident to the execution of removal orders” and thus is barred from judicial review. JA 115. Alternatively, the magistrate judge recommended dismissal on the merits, concluding that, as an excludable alien, Sierra “has no right to be set free in this country.” JA 118.
. See Reply Br. of appellant at 1 ("this case is about the application of a statute as interpreted by the Supreme Court and not Constitutional law”). Nor does Sierra currently maintain that he improperly is being denied visits with his family or that his continued detention violates international law.
. The district court did not address this issue.
. The general rule of inapplicability in section 309(c)(1) of IIRIRA provides as follows:
(c) TRANSITION FOR CERTAIN ALIENS. -
(1) GENERAL RULE THAT NEW RULES DO NOT APPLY. - Subject to the succeeding provisions of this subsection, in the case of an alien who is in exclusion or deportation proceedings before [April 1, 1997,] -
(A) the amendments made by this subtitle shall not apply, and
(B) the proceedings (including judicial review thereof) shall continue to be conducted without regard to such amendments.
. In
Chi Thon Ngo v. INS,
. Originally the title of section 309(c) of IIR-IRA read "Transition For Aliens In Proceedings.” Section 203(a)(2) of the Nicaraguan Adjustment and Central American Relief Act, Pub.L. No. 105-100, tit. II, 111 Stat. 2193, 2198 (1997), amended by Pub.L. No. 105-139, 111 Stat. 2644 (1997), changed the title to its current form which is "Transition For Certain Aliens.”
. In Zadvydas the Supreme Court did not reverse the court of appeal's determination that section 1231(a)(6) was the applicable statute. Indeed, without addressing the issue, the Supreme Court assumed in Zadvydas that section 1231(a)(6) was applicable.
. The dissenting judges in
Rosales-Garcia
did not accept the government's argument that section 1231(a)(6) was inapplicable.
See Rosales-Garcia,
. Though the Supreme Court applied IIRI-RA in
Zadvydas,
it did not explain why it did so.
See Rosales-Garcia,
.
Chevron U.S.A., Inc. v. Natural Res. Def. Council, Inc.,
. The government attempts to explain the position it took in
Zadvydas v. Underdown
by arguing that because of an alleged ambiguity created by the various statutory changes, both the pre-1996 and post-1996 detention statutes governed Zadvydas' imprisonment. See Br. of appellee at 22. As the ACLU points out, this argument is not persuasive.
See
Br. of amicus at 17-22; see
also Chavez-Rivas v. Olsen,
. The ACLU also points out that the government has maintained that the newly enacted "reinstatement” of removal provision, IIRIRA § 241(a)(5), applies to aliens in proceedings before IIRIRA's effective date because those aliens were no longer in ongoing proceedings and section 309(c)(1)
is
therefore inapplicable.
See
Br. of amicus at 17 (citing Brief for respondent in
Castro-Cortez v. INS
at 38-39, No. 99-70267 (9th Cir.) (filed Mar. 27, 2000) (referencing section 309(c)(1) and arguing that "[u]nless an alien is in deportation or exclusion proceedings when the INS attempts to reinstate the alien’s prior order, section 241(a)(5) applies to the alien.”) (copy attached to amicus brief as Exh. C)). Relatedly, in St.
Cyr
the INS argued that “Congress’ comprehensive establishment of a new immigration framework ... shows its intent that, after a transition period, the provisions of the old law should no longer be applied at all.”
St. Cyr,
, None of the judges of the en banc court in Rosales-Garcia accepted the government's argument. We also note that, as Sierra points *569 out, the government's petition for a writ of certiorari in Rosales-Garcia did not ask that the Supreme Court review the court of appeal's holding that section 1231(a)(6) applies to Mariel Cubans who, like Sierra, were in immigration proceedings prior to IIRIRA’s effective date. See Reply Br. of appellant at 2.
.As the court of appeals noted in
Rosales-Garcia, "[i]
nasmuch as shifting agency interpretations issued in
regulations
are accorded less deference under the highly deferential
Chevron
standard, we see no reason why we should respect shifting agency interpretations expressed in briefs.”
. Our quotation from
Chavez-Rivas
should not be taken as a signal that we are critical of the government with respect to its attempt to apply IIRIRA temporally as the statute surely is not clear.
See Chi Thon Ngo v. INS,
. If we had concluded that the government is correct that pre-IIRIRA law governs the
*570
detention, we would have held that the Attorney General has the authority to detain Sierra indefinitely pending his deportation and thus we would have affirmed the denial of his petition for a writ of habeas corpus.
See Chi Thon Ngo v. INS,
. In
Leng May Ma,
the Court noted that "[f]or over a half century this Court has held that the detention of an alien in custody pending determination of his admissibility does not legally constitute an entry though the alien is physically within the United States.”
.The Court further has explained that aliens seeking admission, such as Sierra, have no constitutional rights regarding their applications for admission. See
Landon v. Plasencia,
. The government does not contend that repatriation by Cuba of Sierra is reasonably foreseeable.
. Various district courts have come to the same conclusion.
See, e.g., Gonzalez v. Ashcroft,
. Notwithstanding
Zadvydas, Mezei
plainly remains good law.
See Hoyte-Mesa,
Supreme Court has recently and emphatically instructed us that we should leave the overruling of Supreme Court precedents to that Court, even if we believe, or divine, that the Court should, or will, overrule them. Agostini v. Felton,521 U.S. 203 , 237,117 S.Ct. 1997 , 2017,138 L.Ed.2d 391 (1997). No matter how much the court may disagree with the distinction between excludable and deportable aliens, it simply cannot be disputed that the controlling .Supreme Court precedent makes that distinction and holds that excludable aliens do not have a constitutional right to-be permitted to remain in the United States at liberty if their removal cannot be seasonably obtained.
. Sierra relies on three cases to support his position that once the Supreme Court interpreted section 1231(a)(6), that interpretation applies to all immigrants:
Rosales-Garcia
and
Xi,
both of which held that Zadvydas’s holding applies to excludable/inadmissible aliens, and
Chmakov v. Blackman,
[n]or does some of the broad-sweeping language of Chmakov point to a contrary con- *575 elusion.... This language ... is part of the court’s analysis of whether or not IIRI-RA 'clearly' withdraws habeas jurisdiction. The INS had claimed that the very language in IIRIRA that the Supreme Court found insufficiently clear in St. Cyr could nonetheless be clear enough to withdraw habeas jurisdiction for Chmakov. The Chmakov court, in rejecting that argument, simply concluded that what the Supreme Court had already found unclear could not magically become clear. The reference to the ‘background or pedigree of the petitioner’ likely is meant only to emphasize the fact that the standard for statutory clarity is the same regardless of whether the clear statement rule is supplied by the avoidance canon or by common law principles.

The ACLU cites two cases in an attempt to support its argument that a Supreme Court interpretation based on the avoidance canon necessarily binds all subsequent interpretations of the statute,
