Bernabe Lozano Valverde and Agustina Magdalena Flores Rebollar, natives and citizens of Mexico, petition pro se for review of the Board of Immigration Appeals’ (“BIA”) order denying their motion to reopen. Our jurisdiction is *2 governed by 8 U.S.C. § 1252. We review for abuse of discretion the denial of a motion to reopen. Najmabadi v. Holder , 597 F.3d 983, 986 (9th Cir. 2010). We deny in part and dismiss in part the petition for review.

Petitioners do not raise, and therefore have waived, any challenge to the BIA’s dispositive determination that their motion to reopen was untimely. See Rizk v. Holder , 629 F.3d 1083, 1091 n.3 (9th Cir. 2011) (issues not raised in an opening brief are waived). Petitioners’ contention that the BIA failed to adequately explain its decision is not supported by the record. See Najmabadi , 597 F.3d at 990 (what is required is that the BIA adequately considered evidence and sufficiently announced its decision).

To the extent petitioners challenge the BIA’s decision not to invoke its sua sponte authority to reopen, we lack jurisdiction over that contention. See Mejia- Hernandez v. Holder , 633 F.3d 818, 823-24 (9th Cir. 2011).

We lack jurisdiction to consider petitioners’ contentions challenging the BIA’s September 14, 2006, order denying cancellation of removal because this petition for review is not timely as to that order. See 8 U.S.C. § 1252(b)(1) (“The petition for review must be filed not later than 30 days after the date of the final order of removal.”).

In light of this disposition, we do not reach petitioners’ equal protection claims.

PETITION FOR REVIEW DENIED in part; DISMISSED in part.
