Juan Chavez-Arroyo (Chavez) and Irene Lechuga-Gutierrez (Lechuga), natives and citizens of Mexico, seek a petition for review of the order of the Board of Immigration Appeals (BIA) denying their applications for cancellation of removal pursuant to 8 U.S.C. § 1229b. They argue that the BIA violated their due process rights by not sufficiently considering testimony that their son would suffer extreme hardship if they are removed.

We generally review only the BIA’s decision except to the extent that the decision of the immigration judge (IJ) influences the BIA. Moin v. Ashcroft, 335 F.3d 415, 418 (5th Cir. 2003). With respect to the determination that Chavez and Lechu-ga failed to demonstrate that their son would suffer an “exceptional and extremely unusual hardship” as required under § 1229b, we lack jurisdiction to review this purely discretionary decision. See 8 U.S.C. § 1252(a)(2)(B)(i); Sung v. Keisler, 505 F.3d 372, 377 (5th Cir. 2007); Rueda v. Ashcroft, 380 F.3d 831, 831 (5th Cir. 2004). We reject Chavez’s and Lechuga’s attempt to recast what amounts to a disagreement with the weighing and consideration of the relevant factors by the IJ as a constitutional or legal issue. See Hadwani v. Gonzales, 445 F.3d 798, 801 (5th Cir. 2006).

Because the petitioners did not initiate a request for voluntary departure until after the BIA’s grant of voluntary departure had expired, we decline to grant their request and need not consider whether this court even has the authority to extend an expired grant of voluntary departure. See Faddoul v. INS, 37 F.3d 185, 192 (5th Cir. 1994); Farzad v. INS, 808 F.2d 1071, 1072 (5th Cir. 1987); Compare Bocova v. Gonzales, 412 F.3d 257, 266 (1st Cir. 2005).

DISMISSED FOR LACK OF JURISDICTION.
