Amir Ali petitions for review of the Board of Immigration Appeals’ (BIA) denial of his motion to reopen immigration proceedings. Ali contends that the BIA abused its discretion in denying his motion to reopen, which raised the claim that counsel was ineffective for failing to request voluntary departure on his behalf. Ah has abandoned the remaining ineffective-assistance claims raised in his motion to reopen by failing to argue them in his petition for review. See Yohey v. Collins, 985 F.2d 222, 224-25 (5th Cir. 1993); Soadjede v. Ashcroft, 324 F.3d 830, 833 (5th Cir . 2003).

We review the denial of a motion to reopen under “a highly deferential abuse-of-discretion standard.” Zhao v. Gonzales, 404 F.3d 295, 303 (5th Cir. 2005). Our review of constitutional challenges is de novo. Altamirano-Lopez v. Gonzales, 435 F.3d 547, 549 (5th Cir. 2006). Likewise, we review de novo the BIA’s legal conclusions. Singh v. Gonzales, 436 F.3d 484, 487 (5th Cir. 2006).

“ ‘[T]he failure to receive relief that is purely discretionary in nature does not amount to a deprivation of a liberty interest.’ ” Assaad v. Ashcroft, 378 F.3d 471, 475 (5th Cir. 2004) (citations omitted). A request for voluntary departure is a request for discretionary relief. Eyoum v. INS, 125 F.3d 889, 891 (5th Cir. 1997). Even if Ali had a constitutional right to effective assistance of counsel during the immigration proceedings, he had no due process right to effective assistance of counsel in pursuit of discretionary relief. Gutierrez-Morales v. Homan, 461 F.3d 605, 609 (5th Cir. 2006); Mireles-Valdez v. Ashcroft, 349 F.3d 213, 219 (5th Cir. 2003). Ali’s argument that his case is distinguishable from Assaad because he “was unable to even request the relief’ is unavailing. Cf. Gutierrez-Morales, 461 F.3d at 609-10 (holding that alien has no due process right to effective assistance of counsel in seeking to present waiver application— *469 purely discretionary relief — to the Immigration Judge or the BIA on its merits).

The petition for review is DENIED.
