    UNITED STATES of America, Plaintiff-Appellee v. Bobby KHABEER, Defendant-Appellant.
    No. 13-1048.
    United States Court of Appeals, Eighth Circuit.
    Submitted: July 26, 2013.
    Filed: Aug. 5, 2013.
    Jane W. Duke, Stephanie Mazzanti, Cameron Charles McCree, U.S. Attorney’S Office, Little Rock, AR, for Plaintiff-Ap-pellee.
    Bobby Khabeer, Forrest City, AR, pro se.
    James Phillips, Little Rock, AR, for Defendant-Appellant.
    Before LOKEN, COLLOTON, and KELLY, Circuit Judges.
   PER CURIAM.

After Bobby Khabeer pleaded guilty to a drug-conspiracy charge, the district court concluded that he was a career offender within the meaning of U.S.S.G. § 4B1.1 and sentenced him to 188 months in prison and four years of supervised release. Khabeer appeals. His counsel has filed a brief under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), and seeks leave to withdraw. In the An-ders brief, counsel argues that the district court improperly considered two of Kha-beer’s prior drug-trafficking convictions as separate convictions for purposes of determining that he was a career offender. See U.S.S.G. § 4Bl.l(a) (describing requirements for career-offender status, including that defendant had at least two prior convictions of crime of violence or controlled-substance offense).

Although Khabeer received concurrent sentences on the same day for both of the prior convictions, he was arrested for the offense conduct underlying the first conviction before he engaged in the offense conduct underlying the second conviction. The court was therefore required to consider the convictions as separate. See U.S.S.G. § 4A1.2(a)(2); United States v. Lublin, 981 F.2d 367, 371 (8th Cir.1992) (standard of review).

Having independently reviewed the record under Penson v. Ohio, 488 U.S. 75, 80, 109 S.Ct. 346, 102 L.Ed.2d 300 (1988), we have found no nonfrivolous issues. Accordingly, we grant counsel’s motion to withdraw, and we affirm. 
      
      . The Honorable James M. Moody, United States District Judge for the Eastern District of Arkansas.
     
      
      . Counsel also raises as possible issues whether Khabeer was competent to proceed, whether he was afforded his rights to allocution and counsel, and whether his bottom-of-the-Guidelines-range sentence fell within the Guidelines range and statutory limits. The record before us demonstrates that each of these arguments is unavailing, and we reject them without further discussion.
