PER CURIAM.
Alani Olusegun Arawole appeals the district court order denying his motion for leave to amend his 28 U.S.C.A § 2255 (West Supp.2000) motion and the amended § 2255 motion. Arawole has also filed a motion to stay district court proceedings pending the outcome of this appeal. We dismiss the appeal for lack of jurisdiction because the court’s order is not appealable. This court may exercise jurisdiction only over final orders, 28 U.S.C. § 1291 (1994), and certain interlocutory and collateral orders, 28 U.S.C. § 1292 (1994); Fed. R.Civ.P. 54(b); Cohen v. Beneficial Indus. Loan Corp., 337 U.S. 541, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949). An order denying a motion for leave to amend the § 2255 motion and the amended § 2255 motion is neither a final order nor an appealable interlocutory or collateral order.
We deny a certificate of appealability, dismiss the appeal as interlocutory, and deny the motion to stay as moot. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.
DISMISSED.
