OPINION

John M. Banda, Jr. appeals the order of the United States District Court for the District of New Jersey dismissing his civil rights action.

Banda was civilly committed pursuant to an order of involuntary commitment under the New Jersey Sexually Violent Predator Act (“Act”) and is currently a resident of the Special Treatment Unit Annex (“STU Annex”) at Avenel, New Jersey. He filed a complaint pursuant to 42 U.S.C. § 1983 against the STU Annex and numerous individual mental health professionals involved in his treatment and/or evaluation. In the complaint, Banda alleged that the defendants violated his constitutional rights when they abused their authority and unlawfully caused his civil commitment under the Act, even though he was not convicted of a sex offense. Banda alleged that the treatment he receives at *287 the facility is forcing him to admit to sex crimes. As relief, Banda sought unrestricted release from confinement, ex-pungement of his court records, and $255 million in damages. After granting Banda in forma pauperis status, the District Court dismissed his complaint under 28 U.S.C. § 1915(e)(2)(B)(ii) for failure to state a claim upon which relief may be granted.

Banda timely filed a notice of appeal. We have appellate jurisdiction pursuant to 28 U.S.C. § 1291. Having granted Banda leave to proceed in forma pauperis on appeal, we must now determine whether Banda’s appeal should be dismissed pursuant to 28 U.S.C. § 1915(e)(2)(B). An appeal may be dismissed as frivolous if it has no arguable basis in law or fact. Neitzke v. Williams, 490 U.S. 319, 325, 109 S.Ct. 1827, 104 L.Ed.2d 338 (1989).

Banda’s section 1983 action essentially alleged that he was involuntarily committed, in violation of his civil rights, based on false information and reports, non-sex-related convictions, and deliberate mis-diagnoses by defendants. The District Court properly held that Banda’s claim for immediate release must be sought through a petition for a writ of habeas corpus. See Preiser v. Rodriguez, 411 U.S. 475, 500, 93 S.Ct. 1827, 36 L.Ed.2d 439 (1973); see also Souder v. McGuire, 516 F.2d 820, 823 (3d Cir. 1975) (involuntary commitment is a type of “custody” actionable under the habeas statute). Further, Banda’s claims are not cognizable under section 1983 because a favorable outcome would necessarily imply the invalidity of his confinement. See Wilkinson v. Dotson, 544 U.S. 74, 125 S.Ct. 1242, 1247-48, 161 L.Ed.2d 253 (2005); Heck v. Humphrey, 512 U.S. 477, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994). Accordingly, the District Court properly dismissed the complaint. We note, however, that a dismissal here should be without prejudice to his bringing a section 1983 action if he is ultimately successful in invalidating his civil commitment. See Heck 512 U.S. at 486-87, 114 S.Ct. 2364. 1

For the foregoing reasons, Banda’s appeal will be dismissed under 28 U.S.C. § 1915(e)(2)(B) for lack of legal merit.
