Johnny McGuire Hammack seeks to appeal the district court’s order denying his 28 U.S.C. § 2255 (2000) motion as untimely. 28 U.S.C. § 2244(d)(1) (2000). An appeal may not be taken from the final order in a § 2255 proceeding unless a circuit justice or judge issues a certificate of appealability. 28 U.S.C. § 2253(c) (2000). A certificate of appealability will not issue absent “a substantial showing of the denial of a constitutional right.” 28 U.S.C. § 2253(c)(2) (2000). A prisoner satisfies this standard by demonstrating that reasonable jurists would find the district court’s assessment of his constitutional claims is debatable or wrong and that any dispositive procedural rulings by the district court are likewise debatable. See Miller-El v. Cockrell, 537 U.S. 322, 336-38, 123 S.Ct. 1029, 154 L.Ed.2d 931 (2003); Slack v. McDaniel, 529 U.S. 473, 484, 120 S.Ct. 1595, 146 L.Ed.2d 542 (2000); Rose v. Lee, 252 F.3d 676, 683-84 (4th Cir. 2001). We have independently reviewed the record and conclude that Hammack has not made the requisite showing. Accordingly, we deny a certificate of appealability, dismiss the appeal, and deny Hammack’s request to proceed on appeal in forma pauperis. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials be*756fore the court and argument would not aid the decisional process.
