PER CURIAM: Billy Frederick Allen, Texas prisoner# 366613, appeals the district court’s dismissal of his 42 U.S.C. § 1983 suit pursuant to 28 U.S.C. § 1915A(b)(1). Allen argues that the defendants violated his constitutional rights in connection with his prior and pending state habeas proceedings and that the district court failed to let him adequately develop his claims. As Allen’s claim of denial of access to courts is raised for the first time in his appeal to this court, it is not considered. See Leverette v. Louisville Ladder Co., 183 F.3d 339, 342 (5th Cir.1999).
Although couched in terms of civil rights violations, Allen’s claims arise from his state court habeas proceedings. Under the Rooker-Feldman doctrine, he may not attempt to invalidate a state-court judgment in federal court. See Liedtke v. State Bar of Texas, 18 F.3d 315, 317 (5th Cir.1994). In addition, Allen’s challenge to his pending state habeas proceeding does not allege a violation of his civil rights. As he concedes, the state district court judge has recommended that his pending petition be granted.
Allen’s challenge to specific state habeas proceedings also fails to raise a constitutional question cognizable in federal habeas corpus proceedings. See Nichols v. Scott, 69 F.3d 1255, 1275 (5th Cir.1995). Accordingly, the district court did not err in dismissing Allen’s complaint pursuant to § 1915A(b)(l). Allen’s appeal is without arguable merit and is dismissed as frivolous. See 5th Cir. R. 42.2; Howard v. King, 707 F.2d 215, 219-20 (5th Cir.1983).
Allen is warned that the dismissal of this appeal as frivolous and the district court’s dismissal of his § 1983 suit count as strikes for purposes of 28 U.S.C. § 1915(
g) and that if he accumulates three strikes, he will not be able to proceed in forma pauperis in any civil action or appeal filed while he is incarcerated or detained in any facility unless he is under imminent danger of serious physical injury. See Adepegba v. Hammons, 103 F.3d 383, 388 (5th Cir.1996); § 1915(g). APPEAL DISMISSED AS FRIVOLOUS; SANCTION WARNING ISSUED. Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4. See Rooker v.
Fidelity Trust Co., 263 U.S. 413, 44 S.Ct. 149, 68 L.Ed. 362 (1923), and District of Columbia Court of Appeals v. Feldman, 460 U.S. 462, 103 S.Ct. 1303, 75 L.Ed.2d 206 (1983).
