OPINION
Petitioner Gamil Al-Najar appeals from a decision of the Board of Immigration Appeals (“BIA”) affirming the Immigration Judge’s (“IJ”) opinion that Al-Najar failed to meet his burden of proof for establishing eligibility for asylum, withholding of removal, and protection under the Convention Against Torture, and holding that Al-Najar was eligible for removal due to a 2002 Michigan state conviction for possession of a controlled substance. Al-Najar argues that he is not subject to removal because his prior conviction did not in fact involve a controlled substance and because his plea of guilty was withdrawn and his conviction vacated. Al-Najar argues further that the IJ abused its discretion in declining to continue Al-Najar’s case, the IJ breached a duty to inform Al-Najar that he was eligible for relief under Immigration Nationality Act § 212(h), 8 U.S.C. § 1182, he was entitled to voluntary departure, and he had demonstrated that he was qualified for asylum, withholding of removal, and withholding under the Convention Against Torture (“CAT”).
The government urges us to remand to the BIA so that the agency may determine whether Al-Najar’s conviction for possession of khat constitutes possession of a controlled substance. In the alternative, the government argues that Al-Najar may not collaterally attack his state conviction; the BIA found correctly that petitioner’s conviction applied for immigration purposes; this court lacks jurisdiction to consider Al-Najar’s requests for continuance and voluntary departure; the IJ did not err in failing to provide petitioner the opportunity to apply for a § 212(h) waiver; and Al-Najar has waived review of the denial of his petition for asylum, withholding of removal, and withholding under the CAT. Al-Najar opposes a remand.
For the reasons stated below, we hold that a remand is unnecessary because Al-Najar’s challenge to his Michigan state court conviction constitutes an impermissible collateral attack. Because Al-Najar presents no other claims that would entitle him to relief, we deny the petition for review.
I.
Petitioner Gamil Al-Najar, a native and citizen of Yemen, was admitted to the United States on March 31, 2000, as a conditional resident because of his marriage to an American citizen. On December 14, 2001, Al-Najar was arrested in Dearborn, Michigan for possession of a controlled substance, after having been found selling khat at a Dearborn area convenience store. 1 He pleaded guilty to the charge on July 31, 2002, and received a sentence of probation and a fine of $300. Al-Najar was discharged from probation on July 1, 2003, for the successful completion of his probationary requirements, and his case was dismissed.
*712 On August 27, 2003, the former Immigration and Naturalization Service, now the Department of Homeland Security (“DHS”), served AI-Najar with a Notice to Appear, charging him with removability, pursuant to 8 U.S.C. § 1227(a)(2)(B)(i), based on his controlled substance conviction. Al-Najar responded by requesting asylum pursuant to 8 U.S.C. § 1158, withholding of removal pursuant to 8 U.S.C. § 1231(b)(3), protection under the CAT, and, in the alternative, voluntary departure pursuant to 8 U.S.C. § 1229c.
After a hearing on his asylum petition, the IJ rejected Al-Najar’s claim, finding that his petition was untimely because it was filed more than one year after his arrival to the United States. Furthermore, the IJ concluded — even assuming that Al-Najar’s petition was timely — that Al-Najar’s petition was meritless because Al-Najar lacked credibility due to his failure to disclose an arrest for failure to obey a police officer, and he had failed to establish that he had suffered any past persecution while he lived in Yemen. Finally, the IJ found that Al-Najar did not show that it was more likely than not that he would be tortured upon his return to Yemen.
Al-Najar appealed the IJ’s decision to the BIA. While his appeal was pending, counsel for Al-Najar filed a Motion for Withdrawal of Guilty Plea, For New Trial, and For Dismissal of Charges with the Dearborn trial court. The motion, which was premised explicitly on M.C.R. § 2.612(C)(1)(e) and (f), stated, in pertinent part:
2. That on July 31, 2002, Defendant Gamil Al-Najar pled guilty to the charge of possession of a controlled substance, an apparent violation of Dearborn City Ordinance 14-157;
3. That Defendant pled guilty on advice of his then counsel and received probation for 9 months and was successfully discharged from probation on July 1 st, 2003;
4. That Defendant has complied with all the conditions set by this Court and has not been subsequently arrested by any authority for any other violations of criminal law;
5. That grounds for holding Defendant guilty of violating Dearborn City Ordinance 14-157 do not otherwise exist independent of Defendant’s plea of guilty, which he moves to withdraw forthwith;
6. That insofar as there are no other grounds for holding Defendant] guilty of the charge listed above, it is therefore not equitable that the judgment should have prospective application.
The motion was granted without explanation on June 15, 2005.
The BIA upheld the IJ’s decision, agreeing that Al-Najar is “statutorily ineligible for asylum” because of his untimely application, that petitioner “failed to meet his burden to establish by sufficiently consistent and credible testimony that it is more likely than not that he would be persecuted on account of a protected ground,” and that Al-Najar “failed to meet his burden of proof to establish that it is more likely than not that he would be tortured if returned to Yemen.” The BIA, quoting from Matter of Pickering, 23 I & N Dec. 621 (BIA 2003), also rejected petitioner’s argument that the June 15, 2005, vacatur of his conviction rendered him ineligible for removal, explaining that Al-Najar had not “demonstrated whether his plea of guilty was vacated for ‘reasons solely related to rehabilitation or immigration hardships’ or ‘on the basis of a procedural or substantive defect in the underlying criminal proceedings.’ ” The BIA further rejected Al-Najar’s claim that the IJ erred in failing to continue his proceedings and that *713 the IJ erred in denying him the opportunity to apply for a waiver of inadmissability pursuant to 8 U.S.C. § 1182. The BIA did not address Al-Najar’s argument, raised in an August 12, 2005, Motion for Leave to File Supplemental Brief, that his conviction for possessing khat was not a violation of any law relating to a controlled substance under the Controlled Substances Act (“CSA”). Al-Najar timely petitioned this court for review.
II.
The DHS charged Al-Najar with removability pursuant to 8 U.S.C. § 1227, which sets out the class of deportable aliens, including:
Any alien who at any time after admission has been convicted of a violation of (or a conspiracy or attempt to violate) any law or regulation of a State, the United States, or a foreign country relating to a controlled substance (as defined in section 802 of Title 21), other than a single offense involving possession for one’s own use of 80 grams or less of marijuana, is deportable.
8 U.S.C. § 1227(a)(2)(B)®. Al-Najar spends the bulk of his brief on appeal arguing that khat is not a controlled substance under the CSA, and therefore he is not removable under § 1227(a)(2)(B)®. 2
The government urges us to remand to the BIA so it may determine whether Al-Najar’s conviction qualifies him for removal, relying on the Supreme Court’s decision in
INS v. Ventura,
Generally speaking, a court of appeals should remand a case to an agency for decision of a matter that statutes place primarily in agency hands. This principle has obvious importance in the immigration context. The BIA has not yet considered the “changed circumstances” issue. And every consideration that classically supports the law’s ordinary remand requirement does so here. The agency can bring its expertise to bear *714 upon the matter; it can evaluate the evidence; it can make an initial determination; and, in doing so, it can, through informed discussion and analysis, help a court later determine whether its decision exceeds the leeway that the law provides.

Four years later, in
Gonzales v. Thomas,
We conclude that
Ventura
and
Thomas
do not compel a remand in this case. The questions at issue in
Ventura
— whether circumstances had changed in the petitioner’s home country enough to overcome a presumption of future persecution — and
Thomas
— whether membership in a particular family is considered membership in a “particular social group” — are ones within the BIA’s expertise. Thus, the BIA’s resolutions of these issues are generally given deference by a court of appeals.
See Mostafa v. Ashcroft,
More importantly, however, a remand is unnecessary because Al-Najar’s petition is premised on a futile collateral attack on his Michigan state conviction. An alien petitioner may not collaterally attack a criminal conviction that serves as the basis for the DHS’s initiation of removal proceedings against the alien, regardless of whether the attack is raised in a habeas petition or, as it is here, on review from a decision of the BIA.
See Taylor v. United States,
Al-Najar argues that his guilty plea to possessing khat was akin to pleading guilty to possessing sugar, in that neither substance is listed as a controlled substance under the CSA. But Al-Najar did not plead guilty to possessing khat any more than he pleaded guilty to possessing sugar. Rather, he pleaded guilty to possession of a controlled substance, in violation of Mich. Comp. Laws § 333.7411. By entering his plea of guilty, Al-Najar admitted that the substance he possessed on December 14, 2001, was a controlled substance. He cannot now collaterally attack that conviction in these removal proceedings, absent any claim that his plea was constitutionally invalid or that he was deprived of counsel.
See Bonds,
III.
Next, Al-Najar argues that his Michigan state conviction should not be used against him in these removal proceedings because it has been vacated. We hold that the government has met its burden of proof to show that Al-Najar’s conviction was vacated because of Al-Najar’s fulfillment of probationary rehabilitation requirements. 4 Therefore, we conclude that the conviction may serve as a predicate offense for Al-Najar’s removal.
The determinative question is whether, despite the vacatur of his state court conviction for possession of a controlled substance, Al-Najar remains “convicted” of a law relating to a controlled substance. The INA defines “conviction” as:
[A] formal judgment of guilt of the alien entered by a court or, if adjudication of guilt has been withheld, where— (i) a judge or jury has found the alien guilty or the alien has entered a plea of guilty or nolo contendere or has admitted sufficient facts to warrant a finding of guilt, and (ii) the judge has ordered some form of punishment, penalty, or restraint on the alien’s liberty to be imposed.
8 U.S.C. § 1101(a)(48)(A).
In
Pickering v. Gonzales
(amended opinion),
In
Sanusi v. Gonzales,
Applying Sanusi we hold that the government has met its burden to show that Al-Najar’s conviction was vacated solely for rehabilitative purposes. Although Al-Najar now argues that khat is not a controlled substance as defined in either the CSA or Mich. Comp. Laws § 333.7411, he presented no such claim in his Motion for Withdrawal of Guilty Plea. Rather, his motion invoked M.C.R. § 2.612(C)(1)(e), which allows for the relief of a judgment where the “judgment has been satisfied, released, or discharged.” Al-Najar’s motion was thus predicated on his claim that he had “complied with all the conditions set by [the State’s Nineteenth District Court] and ha[d] not been subsequently arrested by any authority for any other violations of criminal law....” In light of Al-Najar’s discharge from probation because of his completion of his probationary requirements and the reference to M.C.R. § 2.612(C)(1)(e), along with the absence of any substantive legal basis cited in his motion to withdraw, the only reasonable inference to draw is that Al-Najar’s conviction was vacated solely for rehabilitative purposes. As Pickering makes clear, this is an insufficient basis to disregard Al-Najar’s conviction for possession of a controlled substance in these removal proceedings. We therefore affirm the BIA’s ruling that Al-Najar is subject to removal pursuant to 8 U.S.C. § 1227(a)(2)(B)®.
IV.
Al-Najar next challenges the IJ’s denial of his requests for a continuance and for voluntary departure. As the government argues correctly, we lack jurisdiction to review the IJ’s denial of voluntary departure. 8 U.S.C. § 1252(a)(2)(B)® (declaring that “no court shall have jurisdiction to review ... any judgment regarding the granting of relief under ... [8 U.S.C.
*717
§ 1229c]”);
see also Abu-Khaliel v. Gonzales,
However, we have jurisdiction to consider Al-Najar’s request for a continuance.
Abu-Khaliel,
We conclude that the IJ did not abuse its discretion. First, the IJ had previously granted Al-Najar’s requests for continuances, and this reason alone is a sufficient basis to affirm the IJ.
See Abu-Khaliel,
V.
Al-Najar also asserts that the IJ erred in failing to inform Al-Najar of the availability of relief under 8 U.S.C. § 1182(h), contending that, although AlNajar was represented by counsel in front of the IJ, “it is clear that the attorney representative did not fully understand the intricacies of the proceedings in which he was participating and lacked the legal knowledge to make important arguments on Petitioner’s behalf.” Regardless of the quality of Al-Najar’s representation before the IJ, we do not have jurisdiction over Al-Najar’s claim. Section 1182(h) concludes by providing that “[n]o court shall have jurisdiction to review a decision of the Attorney General to grant or deny a waiver under this subsection.” 8 U.S.C. § 1182(h). Moreover, 8 U.S.C. § 1252(a)(2)(B)(i) strips courts of jurisdiction to review “any judgment regarding the granting of relief under section 1182(h) ... of this title.” In any event, Al-Najar is not eligible for relief under § 1182(h), which applies to aliens who are removable due to a “single offense of simple possession of 30 grams or less of marijuana....” 8 U.S.C. § 1182(h). Thus, even assuming we have jurisdiction to consider this claim, it is without merit.
Finally, Al-Najar argues that the BIA erred in denying his petition for asylum, withholding of removal, and withholding under the CAT. His argument is made without citation to either the record or to any case law and is therefore waived.
United States v. Villareal,
VI.
For these reasons, we deny the petition for review.
Notes
. As we explained in Samatar v. Clarridge, 225 Fed.Appx. 366, 368 (6th Cir.2007) (citations omitted), "Khat, or ‘catha edulis,’ is a shrub which grows wild and as a cash crop in Kenya, Somalia, Yemen, and other countries in Northeastern Africa.” It is "known to contain the psychoactive chemical cathinone, a stimulant ... listed as a Schedule I controlled substance under Ohio [and federal] law. Khat also contains the less potent stimulant, cathine, a Schedule IV controlled substance under Ohio [and federal] law.”
. Although Al-Najar raised this argument for the first time in a supplemental brief to the BIA, we nevertheless may consider his claim. Even assuming that he did not exhaust his administrative remedies by failing to present this argument before the IJ, the government did not argue failure to exhaust on appeal.
See Badwan v. Gonzales,
. In Ventura, the government raised this issue before the BIA, but the BIA failed to comment upon the government’s argument in its disposition of the alien’s petition.
. As Al-Najar notes correctly, the BIA appeared to improperly place the burden on the petitioner to prove that his state court conviction was quashed for non-rehabilitative reasons. As we made clear in
Pickering,
the burden rests on the government to show that a vacated conviction remains valid for immigration purposes.
