   ORDER AND JUDGMENT

Petitioner Efrain Cardenas-Tafoya, born in Mexico, was admitted to the United States as a lawful permanent resident in 1988. In 2005, he was convicted in Colorado state court of conspiracy to distribute or manufacture a controlled substance and sentenced to seven years in prison. Upon his release from custody in 2010, the Department of Homeland Security commenced removal proceedings, charging him with removability as an alien convicted of an aggravated felony, namely, trafficking in a controlled substance. An immigration judge (IJ) ordered Mr. Cardenas-Tafoya removed to Mexico on that basis.

Mr. Cardenas-Tafoya was represented by counsel during the removal proceedings but thereafter retained new counsel. The new attorney filed a motion to reopen with the IJ, asserting that the prior attorney provided ineffective assistance of counsel in failing to investigate and present any defense, that Mr. Cardenas-Tafoya was entitled to derivative U.S. citizenship because his father was a U.S. citizen, and that Mr. Cardenas-Tafoya’s conviction was not an aggravated felony. The IJ issued a ruling on July 9, 2010, denying the motion. The IJ concluded that “the record shows conclusively that [Mr. Cardenas-Tafoya] is deportable for the drug trafficking offense.” Admin. R. at 25. The IJ also concluded that Mr. Cardenas-Tafoya’s evidence of his claim to derivative citizenship was insufficient to overcome the government’s evidence that his father was not a U.S. citizen. The government’s evidence included a contemporaneous birth certificate showing that Mr. Cardenas-Tafoya’s father was born in Mexico, and evidence that the State Department, after an extensive fraud investigation, had posthumously revoked a 1984 passport his father had obtained based on misrepresenting himself as a U.S. citizen. The IJ did not separately address the ineffective assistance claim.

On July 14, 2010, five days after the IJ’s decision, Mr. Cardenas-Tafoya was removed to Mexico. He filed an appeal of the IJ’s decision with the Board of Immigration Appeals (BIA). The BIA received the appeal on August 11, 2010. The BIA dismissed the appeal for lack of jurisdiction on the ground that it was received two days beyond the 30-day limit set out in 8 C.F.R. § 1003.38(b). The BIA also determined that because Mr. Cardenas-Tafoya had been removed prior to filing the appeal, it lacked jurisdiction under 8 C.F.R. § 1003.3(e), which provides that “[departure from the United States of a person who is the subject of deportation proceedings, prior to the taking of an appeal from a decision in his or her case, shall constitute a waiver of his or her right to appeal.” In addition, the BIA “separately note[d]” that the evidence Mr. Cardenas-Tafoya submitted with his motion to reopen “in support of [his] derivative citizenship claim was insufficient to warrant reopening for the reasons set forth by the [IJ].” Admin. R. at 6.

Mr. Cardenas-Tafoya next filed this timely petition for review. In his briefs, however, he has not contested either of the jurisdictional bases for the BIA’s dismissal of his appeal. Instead, he argues the merits of the three claims he presented to the IJ. But to the extent the BIA addressed the merits of appeal, it did so in the alternative; the BIA’s jurisdictional rulings were independent grounds for dismissing the appeal. By not contesting those dis-positive rulings, Mr. Cardenas-Tafoya has forfeited his right to appellate review of them. See Bronson v. Swensen, 500 F.3d 1099, 1104 (10th Cir.2007) (explaining that “the omission of an issue in an opening brief generally forfeits appellate consideration of that issue”). Accordingly, without expressing any opinion on the propriety of the BIA’s rulings, we DENY the petition for review. 
      
       After examining the briefs and appellate record, this panel has determined unanimously that oral argument would not materially assist the determination of this appeal. See Fed. R.App. P. 34(a)(2); 10th Cir. R. 34.1(G). The case is therefore ordered submitted without oral argument. This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. It may be cited, however, for its persuasive value consistent with Fed. R.App. P. 32.1 and 10th Cir. R. 32.1.
     
      
      . Although Mr. Cardenas-Tafoya reserved appeal of the IJ’s removal order, he never filed one.
