Juan Mario Sifuentes-Garcia (Sifuentes) appeals the affirmance by the Board of *278Immigration Appeals (BIA) of the Immigration Judge’s (IJ) denial of a motion for continuance of the removal proceeding. Sifuentes contends that he should have been granted the continuance so that he could challenge the 2003 alien-smuggling conviction that rendered him removable.

*277Article III, § 2, of the Constitution limits federal court jurisdiction to actual cases and controversies. See Spencer v. Kemna, 523 U.S. 1, 7, 118 S.Ct. 978, 140 L.Ed.2d 43 (1998). The case-or-controversy requirement demands that “some concrete and continuing injury other than the now-ended incarceration or parole — some ‘collateral consequence’ of the conviction — must exist if the suit is to be maintained.” Id. (citations omitted).

Tobias has served the sentence that was imposed pursuant to the district court’s finding of contempt. Accordingly, there is no case or controversy for this court to address. The appeal and Tobias’s various motions are rendered moot. See Spencer, 523 U.S. at 7, 118 S.Ct. 978. Accordingly, the appeal is DISMISSED. Tobias’s motion to proceed as a sanctioned litigant is DENIED. All other outstanding motions are DENIED.

*278This court reviews the denial of a continuance for abuse of discretion. Witter v. INS, 113 F.3d 549, 555-56 (5th Cir. 1997). An IJ may grant a continuance upon a showing of good cause. Id.

Sifuentes cites to two BIA decisions having nothing to do with the granting of a continuance, and he makes no argument directly relevant to the “good cause” that must be shown in order to obtain a continuance.

Sifuentes fails to show that the denial of a continuance was an abuse of discretion. His petition for review is DENIED.
