Dismissed by unpublished PER CURIAM opinion.

Unpublished opinions are not binding precedent in this circuit.

Vera C. Harper and David A. Harper appeal the district court’s order dismissing without prejudice their civil complaint and allowing them to file an amended complaint within sixty days of the entry of the court’s order. This court may exercise jurisdiction only over final orders, 28 U.S.C. § 1291 (2006), and certain interlocutory and collateral orders, 28 U.S.C. § 1292 (2006); 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). An order granting leave to amend is interlocutory as it leaves the case open for either amendment of the complaint or entry of final judgment. Jung v. K. & D. Mining Co., 356 U.S. 335, 337, 78 S.Ct. 764, 2 L.Ed.2d 806 (1958) (quoting Missouri & Kansas Interurban Ry. Co. v. City of Olathe, 222 U.S. 185, 186, 32 S.Ct. 46, 56 L.Ed. 155 (1911)); see also Domino Sugar Corp. v. Sugar Workers Local Union 392, 10 F.3d 1064, 1066-67 (4th Cir. 1993) (a dismissal without prejudice is not generally appealable).

Accordingly, we dismiss the appeal for lack of jurisdiction. We further deny Appellants’ motions to supplement the record on appeal and for oral argument. 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.
