MEMORANDUM ***
Jose Luis Artero-Tovar, a native and citizen of El Salvador, petitions pro se for review of an order of the Board of Immigration Appeals (“Board”) affirming without opinion an immigration judge’s denial of his applications for cancellation of removal under Section 203 of the Nicaraguan Adjustment and Central American Relief Act, and for voluntary departure. We vacate and remand in part, and dismiss in part the petition for review.
The immigration judge denied his application for cancellation of removal on three independent grounds: (1) that Artero-Tovar is statutorily ineligible because he failed to establish seven years of continuous physical presence; (2) that Artero-Tovar is statutorily ineligible because his presumption of extreme hardship was overcome by evidence in the record; and (3) that even if Artero-Tovar were eligible, he is not entitled to a discretionary grant of relief. The Board affirmed without opinion.
We have jurisdiction to review whether an alien has met the continuous physical presence requirement, Falcon Carriche v. Ashcroft, 350 F.3d 845, 853 (9th Cir.2003), but we do not have jurisdiction to review whether an alien has satisfied the hardship requirement, which rests in the discretion of the agency. 8 U.S.C. § 1252(a)(2)(B); Romero-Torres v. Ashcroft, 327 F.3d 887, 892 (9th Cir.2003). We also lack jurisdiction to review the ultimate discretionary decision to deny cancellation of removal. 8 U.S.C. § 1252(a)(2)(B); Romero-Torres, 327 F.3d at 890.
Because the Board affirmed without opinion, we have no way of knowing on which ground or grounds the Board affirmed, and in turn whether we have jurisdiction to review the Board’s decision. Lanza v. Ashcroft, 389 F.3d 917, 932 (9th Cir.2004). Accordingly, we vacate the Board’s decision as to the application for cancellation of removal and remand with instructions to clarify the grounds for its affirmance. Id.
We lack jurisdiction to review the denial of Artero-Tovar’s application for voluntary departure, and therefore dismiss this portion of the petition. 8 U.S.C. § 1252(a)(2)(B); Tovar-Landin v. Ashcroft, 361 F.3d 1164, 1166 (9th Cir.2004).
