MEMORANDUM **
Saloun Oum, a native and citizen of Cambodia, petitions for review of the Board of Immigration Appeals’ (“BIA”) order denying Oum’s motion to reopen to allow her to file a brief in support of her appeal from the immigration judge’s denial of her application for asylum and withhold*704ing of removal. We have jurisdiction under 8 U.S.C. § 1252(a). We deny the petition for review in part, and dismiss it in part.
Because petitioner fails to address how the BIA abused its discretion by denying her motion to reopen, and instead challenges the BIA’s underlying order dismissing petitioner’s appeal for failure to timely file a brief, the petitioner has waived her challenge to the BIA’s denial of her motion to reopen. See Martinez-Serrano v. INS, 94 F.3d 1256, 1259-60 (9th Cir.1996).
We lack jurisdiction to review the BIA’s final removal order dismissing petitioner’s appeal because the petition for review of this underlying order is time-barred. See 8 U.S.C. § 1252(b)(1).
PETITION FOR REVIEW DENIED in part, DISMISSED in part.
