Nicie Smith appeals the district court’s 1 dismissal of her civil complaint for lack of subject matter jurisdiction. We conclude that the district court properly dismissed the complaint, because diversity jurisdiction is lacking, see 28 U.S.C. § 1332(a), and Ms. Smith alleged no viable basis for federal-question jurisdiction, see 28 U.S.C. § 1331; Ashcroft v. Iqbal, 556 U.S. 662, 129 S.Ct. 1937, 1949, 173 L.Ed.2d 868 (2009) (threadbare recitals of elements of cause of action supported by mere con- *507 elusory statements are not entitled to assumption of truth); Hull v. Fallon, 188 F.3d 939, 942 (8th Cir. 1999) (requirements for federal question jurisdiction). Accordingly, we affirm the judgment of the district court, see 8th Cir. R. 47B, but we modify the dismissal of Ms. Smith’s complaint to be without prejudice, see Cnty. of Mille Lacs v. Benjamin, 361 F.3d 460, 464 (8th Cir. 2004).
