Mario Lemus, formerly federal prisoner # 56398-019, appeals from the denial of relief in his action, filed in September 2009, seeking recognition that he is an American citizen so that he could have access to prison programs that allow for early release or halfway house placement. He sought transfer to a facility where he could avail himself of such programs. He also sought removal of an immigration detainer against him.

“This Court must examine the basis of its jurisdiction, on its own motion, if necessary.” Mosley v. Cozby, 813 F.2d 659, 660 (5th Cir. 1987). Lemus’s July 2010 release rendered moot his 28 U.S.C. § 2241 claims. See Rocky v. King, 900 F.2d 864, 867 (5th Cir. 1990). Lemus’s claim regarding the removal of the immigration detain-er, whether brought under section 2241 or any other provision of law, was rendered moot by his September 2010 removal to Mexico. See id.

APPEAL DISMISSED.
