MEMORANDUM **

In these consolidated petitions, Juan Francisco Luna Hernandez, a native and *692citizen of Mexico, petitions for review of two Board of Immigration Appeals (“BIA”) orders. Our jurisdiction is governed by 8 U.S.C. § 1252. We review de novo due process claims, Ram v. INS, 243 F.3d 510, 516 (9th Cir. 2001), and questions of law, Fernandez-Ruiz v. Gonzales, 468 F.3d 1159, 1163 (9th Cir. 2006). We dismiss in part and deny in part the petition for review in No. 05-75259 and deny the petition for review in No. 06-73938.

We lack jurisdiction to review the BIA’s discretionary determination that Luna Hernandez failed to show exceptional and extremely unusual hardship. See Martinez-Rosas v. Gonzales, 424 F.3d 926, 930 (9th Cir. 2005).

We reject Luna Hernandez’s contention that the BIA failed to consider all of the evidence. See Fernandez v. Gonzales, 439 F.3d 592, 603 (9th Cir. 2006) (petitioner must overcome presumption that the BIA reviewed the entire record to establish a due process violation).

Contrary to Luna Hernandez’s contention, the BIA’s interpretation of the hardship standard falls within the broad range authorized by the statutory language. See Ramirez-Perez u Ashcroft, 336 F.3d 1001, 1004 (9th Cir. 2003).

We are unpersuaded by Luna Hernandez’s contentions that the BIA erred and violated due process by engaging in de novo review of the IJ’s factual findings. See 8 C.F.R. §§ 1003.1(d)(3)(i)-(ii).

Luna Hernandez has waived any challenge to the BIA’s dismissal of his second administrative appeal. See Martinez-Serrano v. INS, 94 F.3d 1256, 1259-60 (9th Cir. 1996) (issues not specifically raised and argued in a party’s opening brief are waived).

No. 05-75259: PETITION FOR REVIEW DISMISSED in part; DENIED in part.

No. 06-73938: PETITION FOR REVIEW DENIED.
