Maurilio Garza-Sanchez (“Garza”) appeals his conviction of being an alien found in the United States following deportation, in violation of 8 U.S.C. § 1326. He contends that the underlying deportation was unlawful and cannot be used to support his conviction under § 1326. We have jurisdiction pursuant to 28 U.S.C. § 1291. We hold that Garza validly waived the right to appeal his deportation, and cannot collaterally attack it now. Accordingly, we affirm.
FACTS AND PROCEDURAL HISTORY
In 1994, Garza was convicted of possession of a controlled substance, robbery, and possession of methamphetamine for sale. On November 7, 1996, the Immigration and Naturalization Service (“INS”) issued an Order to Show Cause, commencing deportation proceedings against Garza on the basis of his 1994 conviction of possession of methamphetamine for sale. At his final deportation hearing on June 1, 1998, Garza admitted the allegations against him set forth in the Order to Show Cause, and was ordered deported. The immigration judge (“IJ”) advised Garza of his right to appeal, and Garza waived it. He was deported the following day.
Less than three weeks later Garza was found in Los Angeles County. He was indicted for violation of 8 U.S.C. § 1326 on July 28,1998. Garza moved to dismiss the indictment on the ground that the underlying deportation was unlawful. The district court denied Garza’s motion, concluding that he had waived the right to appeal the deportation order, and that he therefore could not collaterally attack the deportation in this prosecution under § 1326. Garza thereafter pleaded guilty, reserving his right to challenge the denial of his motion to dismiss the indictment. This appeal followed.
DISCUSSION
We review de novo a district court’s decision to deny a defendant’s collateral attack on a deportation proceeding.
United States v. Proa-Tovar,
Here, it is undisputed that Garza waived the right to appeal his order of deportation. Garza argues, however, that his waiver was not considered and intelligent because the IJ failed to inform him of possible challenges to his deportation before Garza decided to waive his right to appeal. We review de novo the validity of a waiver of appellate rights.
See United States v. Buchanan,
A
Garza’s argument is based primarily on 8 C.F.R. § 240.49(a), 1 which provides, in part:
*809 The immigration judge shall inform the respondent of his or her apparent eligibility to apply for any of the benefits enumerated in this paragraph and shall afford the respondent an opportunity to make application therefor during the hearing.
According to Garza, the IJ failed to comply with § 240.49 because he did not inform Garza of two possible constitutional challenges to the immigration laws which, if either were successful, would have rendered him eligible for a discretionary waiver of deportation.
First, in 1996 Congress amended 8 U.S.C. § 1182(c) to make discretionary relief from deportation unavailable to aliens who were “deportable” by reason of having been convicted of certain criminal offenses, including the drug offense to which Garza pleaded guilty.
See Estrada-Torres,
Second, Garza contends that he “may have” pleaded guilty to the 1994 drug charge in reliance on the availability of a discretionary waiver under the version of § 1182(c) in effect at the time of his plea. On this basis, Garza argues that during his deportation hearing in 1998 the IJ should have advised him of a potential due process challenge to the retroactive application of the 1996 amendment to § 1182(c). It was this retroactive application of the amended version of § 1182(c) that precluded Garza from obtaining a discretionary’ waiver because of his earlier drug conviction. One of our decisions has since left open in dicta the possibility that “in a rare circumstance” and “under a specific factual showing that a plea was entered in reliance on the availability of discretionary waiver under § 212(c) [of the Immigration and Nationality Act, 8 U.S.C. § 1182(c) ],” an alien may be able to establish that the 1996 amendment to § 1182(c) “has an impermissible retroactive application as to him.”
Magana-Pizano v. INS,
*810 The issue, therefore, is whether § 240.49 required the IJ to inform Garza of these potential constitutional challenges to the immigration laws.
Where a regulation’s meaning is plain and unambiguous, we must construe it to give effect to that meaning.
See Crown Pac. v. Occupational Safety & Health Review Comm’n,
Here, Garza’s contention is inconsistent with the plain and unambiguous language of § 240.49. That regulation requires only that the IJ “inform the respondent of his or her apparent eligibility to apply for any of the benefits enumerated in this paragraph ” (emphasis added). These enumerated benefits are all statutory grounds for relief from deportation found in the immigration laws. 5 A potential constitutional challenge to the immigration laws themselves is not among them. We may not read into this regulation a requirement that it does not impose by its precise terms.
We conclude that § 240.49 did not require the IJ to inform Garza of potential constitutional challenges to the immigration laws. 6
B
Garza contends that even if § 240.49 did not require the IJ to inform him of possible constitutional challenges to his deportation, the Due Process Clause did. We disagree. Garza cites no authority for the proposition that an alien’s waiver of the right to appeal a deportation order is invalid unless the IJ informed him or her of every potential ground for relief, including possible constitutional challenges to the deportation laws.
Garza’s position is vague in principle and unworkable in practice. Consider, for example, Garza’s contention that the IJ should have advised him of a potential equal protection challenge because three courts in various jurisdictions had ruled favorably on such challenges in the past. What if only one court had ruled favorably? What if there were challenges pending in some courts, but no decision had yet been made? What if the possibility of such a challenge had only been suggested in a law review note? What if no one had suggested the possibility of such a challenge, but the IJ might have thought of it? These examples illustrate the potentially expansive and open-ended obligations of an IJ that might follow from Garza’s contention.
Cf. Michelson v. INS,
Established legal principles and case authority point to the conclusion that the
*811
Due Process Clause does not require the IJ to advise of potential constitutional challenges. We have held, for example, that an IJ’s failure to advise an alien of the right to appeal the amount of bail imposed did not render invalid his subsequent waiver of appeal.
See United States v. Corrales-Beltran,
When considering similar challenges to the validity of appeal waivers during deportation proceedings, we also have observed that Rule 11 of the Federal Rules of Criminal Procedure may provide pertinent analogy.
See United States v. Chavez-Huerto,
CONCLUSION
For all of the above reasons, we hold that the IJ had no duty to advise Garza of the potential constitutional challenges Garza describes. Garza’s waiver was considered and intelligent, and therefore valid.
AFFIRMED.
Notes
. In their briefs, both parties cite 8 C.F.R. § 242.17. Effective April 1, 1997, however, that provision was replaced by § 240.49, as part of a comprehensive set of amendments to the INS regulations to implement the provisions of the Illegal Immigration Reform and Immigrant Responsibility Act, Pub.L. No. 104-208, 110 Stat. 3009 (1996). See 62 Fed. Reg. 10312, 10375 (March 6, 1997); 8 C.F.R. § 240.49 (1998). Section 240.49 applies to *809 all deportation proceedings commenced before April 1, 1997, as was Garza's. With respect to the issues raised in this appeal, the differences between §§ 242.17 and 240.49 are not material.
. In
Estrada-Torres,
we held that the INS was mistaken in its interpretation of the statute, and that it applied to aliens in both deportation and exclusion proceedings.
. In his briefs, Garza cites two additional decisions that he says also should have triggered the IJ’s duty to advise him:
Gutierrez-Martinez v. Reno,
.Far from making the "specific factual showing” that we suggested in Magana-Pizano would be required to raise this issue, Garza asserts only the vague claim that he "may have” pleaded guilty in reliance on the availability of a discretionary waiver, and points to no evidence whatsoever that he in fact did rely on the availability of such a waiver.
. Those benefits are enumerated as follows:
The respondent may apply to the immigration judge for suspension of deportation under section 244(a) of the [Immigration and Nationality] Act; for adjustment of status under section 245 of the Act, or under section 1 of the Act of November 2, 1966, or under section 101 or 104 of the Act of October 28, 1977; or for the creation of a record of lawful admission for permanent residence under section 249 of the Act.... In conjunction with any application for creation of status of an alien lawfully admitted for permanent residence made to an immigration judge, if the respondent is inadmissible under any provision of section 212(a) of the Act and believes that he or she meets the eligibility requirements for a waiver of the ground of inadmissibility, he or she may apply to the immigration judge for such waiver.
8 C.F.R. § 240.49.
. In his briefs, Garza also appears to argue that the IJ should have informed him that he might have been eligible for a discretionary waiver of deportation under 8 U.S.C. § 1182(c), even absent any constitutional infirmity. This contention lacks merit. As indicated above, by the time deportation proceedings were commenced against Garza, § 1182(c) had been amended, rendering Garza ineligible for a discretionary waiver because of his prior conviction for methamphetamine possession.
