Before BYE, COLLOTON, and GRUENDER, Circuit Judges.
                           ___________

PER CURIAM.

       Federal inmate William Hawkins appeals the district court’s1 dismissal without
prejudice of his 28 U.S.C. § 2241 petition. Upon careful review, see Mitchell v. U.S.
Parole Comm’n, 538 F.3d 948, 951 (8th Cir. 2008) (per curiam) (de novo review), we
conclude dismissal was proper, see Lopez-Lopez v. Sanders, 590 F.3d 905, 907 (8th
Cir. 2010) (defendant who wishes to collaterally attack his conviction generally must


      1
       The Honorable Billy Roy Wilson, United States District Judge for the Eastern
District of Arkansas, adopting the report and recommendations of the Honorable Joe
Volpe, United States Magistrate Judge for the Eastern District of Arkansas.
do so through 28 U.S.C. § 2255); Langella v. Anderson, 612 F.3d 938, 940-41 (8th
Cir. 2010) (decision whether to grant or deny parole is one Congress has committed
to agency discretion and court has limited jurisdiction to review agency decisions).

      Accordingly, we affirm. See 8th Cir. R. 47B.
