California state prisoner Leonard Neely appeals pro se from the district court’s judgment dismissing his 42 U.S.C. § 1983 action, without prejudice, for failure to exhaust administrative remedies as required by the Prison Litigation Reform Act, 42 U.S.C. § 1997e(a). We have jurisdiction under 28 U.S.C. § 1291. We review de novo the district court’s dismissal for failure to exhaust, and for clear error its factual determinations. Wyatt v. Terhune, 315 F.3d 1108, 1117 (9th Cir.2003). We affirm. The district court properly dismissed the action because Neely did not exhaust administrative remedies before filing his complaint in federal court. See McKinney v. Carey, 311 F.3d 1198, 1199 (9th Cir.2002) (per curiam) (<HOLDING>); see also Ngo v. Woodford, 539 F.3d 1108, 1109
