MEMORANDUM ***

Lead petitioner Antonio Roldan-Gallegos and his wife and three children, all *964natives and citizens of Mexico, petition pro se for review of the Board of Immigration Appeals’ (“BIA”) order adopting and affirming an Immigration Judge’s (“IJ”) decision denying Petitioners’ applications for asylum, withholding of removal, protection under the Convention Against Torture (CAT), and cancellation of removal. To the extent we have jurisdiction, it is conferred by 8 U.S.C. § 1252. We review de novo claims of due-process violations. *Colmenar v. INS,*210 F.3d 967, 971 (9th Cir.2000). We deny in part and dismiss in part the petition for review.

Petitioners contend that the IJ violated due process by ignoring evidence relevant. to their applications for cancellation of removal, and failing to investigate adequately those applications. Contrary to Petitioners’ contentions, the proceedings were not “ ‘so fundamentally unfair that [they were] prevented from reasonably presenting [their] case.’” *Id.*(citation omitted). Moreover, Petitioners have failed to specify what evidence was ignored or not developed, and have not explained how the evidence would have affected the outcome of the proceedings. *See id.*(requiring prejudice to prevail on a due process challenge).

Petitioners also contend that the IJ violated due process by departing from proper procedure, failing to provide them an adequate opportunity to obtain new counsel, failing to investigate adequately the asylum and withholding-of-removal claims, and ignoring evidence relevant to the asylum and withholding-of-removal claims. Even though we construe Petitioners’ pro se notice of appeal to the BIA liberally, see *Barron v. Ashcroft,*358 F.3d 674, 676 n. 4 (9th Cir.2004), we lack jurisdiction to review these contentions because Petitioners failed to raise them before the BIA. *See id.*at, 678 (due process challenges that are “procedural in nature” must be exhausted).

We also lack jurisdiction to review the agency’s discretionary determination that Roldan-Gallegos and Resendiz de Roldan failed to show exceptional and extremely unusual hardship to a qualifying relative. *See Romero-Torres v. Ashcroft,*327 F.3d 887, 892 (9th Cir.2003).

PETITION FOR REVIEW DENIED in part; DISMISSED in part.
