Unpublished opinions are not binding precedent in this circuit.

Jovica Petrovic seeks to appeal the district court’s order entered after a preliminary' screening of Petrovic’s complaint filed pursuant to Bivens v. Six Unknown Named Agents of Fed. Bureau of Narcotics, 403 U.S. 388, 91 S.Ct. 1999, 29 L.Ed.2d 619 (1971). This court may exercise jurisdiction only over final orders, 28 U.S.C. § 1291 (2012), and certain interlocutory and collateral orders, 28 U.S.C. § 1292 (2012); Fed. R. Civ. P. 54(b); Cohen v. Beneficial Indus. Loan Corp., 337 U.S. 541, 545-46, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949). The order Petrovic seeks to appeal is neither a final order nor an appealable interlocutory or collateral order. Accordingly, we deny leave to proceed in forma pauperis and dismiss the appeal for lack of jurisdiction. We dispense with oral argument because the facts and legal conten*166tions are adequately presented in the materials before this court and argument would not aid the decisional process.
