OPINION

Valentine C. Nwandu, a citizen of Nigeria, appeals the district court’s denial of his petition for a writ of habeas corpus pursuant to 28 U.S.C. § 2241. For the reasons set forth below, we affirm the judgment of the district court. 1

I.

Danish authorities found 692 grams of heroin in Valentine C. Nwandu’s (“Nwandu”) possession when he attempted to en *164 ter Denmark using a fake Nigerian passport issued in the name of Valentine Azuka Hayes in February 1983. On May 17, 1983, Nwandu was convicted of the offense of heroin smuggling and sentenced to a period of four years incarceration. Denmark deported Nwandu to Nigeria in June 1985. 2

In July 1985, Nwandu fraudulently obtained a student visa to enter the United States by failing to reveal his prior drug trafficking conviction in Denmark. Subsequently, he married an American citizen and, after his student visa had expired, filed a visa petition and an application for adjustment of status. On May 11, 1994, while this adjustment application was pending, Nwandu applied for and was granted advance parole to leave the United States in order to attend his father’s funeral in Nigeria. Advance parole permitted Nwandu to leave the United States without abandoning his application for adjustment of status. When Nwandu returned from Nigeria on May 31, 1994, he was “paroled” into the United States in accordance with the terms of his advance parole.

Shortly thereafter, the Immigration and Naturalization Service (“INS”) conducted an investigation on Nwandu’s adjustment of status application, which included an adjustment interview on September 6, 1994. During this interview, Nwandu revealed his 1983 drug conviction for the first time. Nwandu was inadmissible to the United States due to, inter alia, his prior drug conviction in Denmark, 8 U.S.C. § 1182(a)(2)(A)(i)(II), and the fact that his initial entry into the United States as a student was obtained by fraud. 8 U.S.C. § 1182(a)(6)(C). Consequently, in July 1995, the INS denied Nwandu’s visa application. Later, in June 1996, the INS terminated Nwandu’s parole status and placed him in exclusion proceedings pursuant to former section 236 of the Immigration and Nationality Act (“INA”), 8 U.S.C. § 1226 (1995). Of special relevance to this appeal, Nwandu was charged with being inadmissible to the United States pursuant to 8 U.S.C. § 1182(a)(2)(A)(i)(II) on account of his earlier drug conviction.

At an exclusion hearing, the Immigration Judge sustained that charge and found Nwandu to be excludable. Subsequently, Nwandu pursued an application for adjustment of status in conjunction with a request for waiver under 8 U.S.C. § 1182(h). Nwandu argued at this second hearing that his 1983 conviction in Denmark for smuggling heroin had been expunged, a claim belied by the government’s ability to obtain — and provide to the Immigration Judge — a properly certified copy of a 1983 record of conviction for smuggling heroin under the name “Valentine Chukvmdu Nwandu.” S.A. 8-13 (emphasis added). Nwandu offered into evidence only a 1999 Danish document purporting to state that “No entry appears in the Central Crime Register” under the name “Valentine Chukwuka Nwandu.” 3 S.A. 22 (emphasis added). Based on the totality of the evidence, which included the conviction record, the criminal court’s notation that Nwandu acted as a courier, and Nwandu’s 1-485 application, in which he stated that he omitted mention of his conviction when obtaining his visa to come to the United *165 States, the Immigration Judge found that, “notwithstanding the respondent’s certificate of criminal record, which states that there is no criminal record pertaining to him, that the allegations contained in the amended Notice to Appear are sustained and that the respondent is excludable as charged.” S.A. 4-5. Nwandu’s application for adjustment of status was then pretermitted because no waiver is available under section 212(h) of the INA, 8 U.S.C. § 1182(h), for a drug conviction involving heroin. S.A. 5.

Nwandu timely appealed this decision to the Board of Immigration Appeals (“BIA”). The BIA held that Nwandu had been properly placed in exclusion proceedings, that the Immigration Judge had properly found him excludable on account of his heroin smuggling in Denmark, and that his adjustment application was properly pretermitted. The BIA denied Nwandu’s motion to reconsider, and he filed a petition for a writ of habeas corpus in the United States District Court for the District of Maryland, which was denied. This appeal followed.

II.

A.

Nwandu first argues that he was not subject to exclusion proceedings upon denial of his adjustment application and revocation of advance parole, and that, even if he was, he was given insufficient notice that he would be subject to exclusion proceedings if his petition for adjustment of status were denied. The relevant regulation, however, clearly states that an exclusion proceeding, not a deportation hearing, was the appropriate means for deciding Nwandu’s status once his application for adjustment of status was denied. The regulation is unequivocal:

The departure of an [adjustment] applicant who is not under deportation proceedings shall be deemed an abandonment of his or her application constituting grounds for termination, unless the applicant was previously granted advance parole by the Service for such absence, and was inspected upon returning to the United States. If the application of an individual granted advance parole is subsequently denied, the applicant will be subject to the exclusion provisions of section 236 of the Act. No alien granted advance parole and inspected upon return shall be entitled to a deportation heañng.

8 C.F.R. § 245.2(a)(4)(ii) (1994) (emphasis added). 4 Thus, once Nwandu’s adjustment application was denied by the INS, Nwandu was subject to exclusion proceedings.

Nwandu also claims that he was given insufficient notice that he could be subject to exclusion proceedings. Nwandu’s advance parole document provided that

[t]his authorization will permit you to resume your application for adjustment of status on your return to the United States.

WARNING: Pursuant to 8 CFR 215.3(a)(2), if your application for adjustment of status is denied, you will be subject to exclusion proceedings under Section 236 of the Immigration and Nationality Act.

J.A. 110 (emphasis in bold in original). 5 While Nwandu’s notice did cite to an incor *166 rect regulation, rather than to 8 C.F.R. § 245.2(a)(4)(ii), we find this to be of no legal significance given that the substance of the applicable regulation was clearly-conveyed. 6

B.

Nwandu provides no better support for his claim that additional protections were owed to him prior to the Immigration Judge’s decision to pretermit his application for adjustment of status and request for a section 212(h) waiver.

In the first place, as a statutory matter, we have no doubt that the Immigration Judge properly pretermitted Nwandu’s adjustment application and request for waiver. In order to be statutorily eligible for adjustment of status, an applicant must be admissible to the United States. 8 U.S.C. § 1255(a). Nwandu was found inadmissible to the United States as a result of his Danish conviction for smuggling heroin. See 8 U.S.C. § 1182(a)(2)(A)(i)(II). 7 No waiver exists for this ground of inadmissibility when the conviction at issue involves heroin. See 8 U.S.C. § 1182(h) (waiver allowed for conviction of simple possession of less than 30 grams of marijuana).

Second, with respect to Nwandu’s constitutional claim regarding expungement, we note that — even if the facts alleged presented a cognizable due process claim — we could find no due process violation. For the Immigration Judge did hear evidence with respect to the claimed ex-pungement of the Danish conviction and, weighing the evidence, resolved the issue in favor of the government. We could not say that the ample procedural protections afforded by the hearings before the Immigration Judge, Nwandu’s opportunity to present evidence, and the review by the BIA, are constitutionally deficient, particularly where Nwandu himself cannot explain how he was prejudiced in fact, or what more he would do if given the opportunity. Indeed, even at the time of oral argument, Nwandu’s counsel was unable to describe a single avenue he would pursue, action he would take, or information he expected to obtain, to strengthen his claim of expungement, beyond the evidence already presented to, and considered by, the Immigration Judge.

We need not resolve that issue, however, because, more fundamentally, an adverse ruling on Nwandu’s claim of expungement — based on Nwandu’s failure to present evidence sufficient to prove expungement to either the Immigration Judge or the BIA, both of whom found that Nwandu was convicted of smuggling heroin — presents no cognizable due process claim. Indeed, such an adverse ruling does not constitute any constitutional violation at all. *167 We decline to review under the aegis of a habeas corpus petition pursuant to section 2241 what amounts to a factual finding by the Immigration Judge that a conviction for heroin smuggling was extant, not expunged. 8 See Bowrin v. U.S. Immigration and Naturalization Service, 194 F.3d 483, 490 (4th Cir. 1999) (“Only questions of pure law will be considered on § 2241 habeas review. Review of factual or discretionary issues is prohibited.”).

C.

Nwandu also argues that because his guilty plea to possession for heroin in Denmark was tendered prior to the enactment of the Antiterrorism and Effective Death Penalty Act of 1996 (“AEDPA”), our decision in Tasios v. Reno, 204 F.3d 544 (4th Cir. 2000), renders him eligible for discretionary waiver under former 8 U.S.C. § 1182(e) (repealed 1996), even if he is not eligible for waiver under 8 U.S.C. § 1182(h). In Tasios, we held that section 440(d) of AEDPA did not bar relief under former section 1182(c) for lawful permanent residents who pled guilty to aggravated felonies, or who conceded deportability prior to AEDPA’s effective date, because it was impermissibly retroactive; under section 1182 as amended, discretionary relief is not available for aliens convicted of drug trafficking offenses.

However, AEDPA does not impose a similar retroactive effect in this case because Nwandu, unlike Tasios, and unlike the individual at issue in St. Cyr v. Immigration and Naturalization Service, 229 F.3d 406 (2d Cir. 2000), cert. granted, 531 U.S. 1107, 121 S.Ct. 848, 148 L.Ed.2d 733 (2001), has never been a lawful permanent resident, and section 1182(c)’s discretionary relief was never available to him. Former section 1182(c) provides only that:

Aliens lawfully admitted for permanent residence status who temporarily proceeded abroad voluntarily and not under an order of deportation, and who are returning to a lawful unrelinquished domicile of seven consecutive years, may be admitted in the discretion of the Attorney General without regard to the provisions of subsection (a) of this section (other than paragraphs (3) and (9)(C)). Nothing contained in this subsection shall limit the authority of the Attorney General to exercise the discretion vested in him under section 1181(b) of this title. The first sentence of this subsection shall not apply to an alien who has been convicted of one or more aggravated felonies and has served for such felony or felonies a term of imprisonment of at least 5 years.

8 U.S.C. § 1182(c) (repealed 1996) (emphasis added). Because Nwandu was never a lawful permanent resident, and never entitled to the benefit of former section 1182(c), Tasios simply does not dictate the result in this case.

Nwandu implicitly acknowledges this, but argues that “[although this section expressly applied to aliens who are *168 lawful permanent residents, [ ] its general principles and approach to deportation waivers should also apply” in his case— even though he is not a lawful permanent resident. See Appellant’s Brief at 26-27. However, AEDPA’s repeal of section 1182(c) cannot be seen, with respect to Nwandu, to “impair rights a party possessed when he acted, increase a party’s liability for past conduct, or impose new duties with respect to transactions already completed,” because discretionary relief was not available to Nwandu prior to AEDPA either. Landgraf v. USI Film Prods., 511 U.S. 244, 269, 114 S.Ct. 1483, 128 L.Ed.2d 229 (1994). As a result, Tasios is unavailing for Nwandu. 9

CONCLUSION

For the foregoing reasons, the district court’s order denying appellant’s motion for a writ of habeas corpus is affirmed. 10

AFFIRMED.
