B. Faihore to Exhaust Tribal Court Remedies
Although “ § 1331 encompasses the federal question whether a tribal court has exceeded the lawful limits of its jurisdiction, ... exhaustion is required before such a claim may be entertained by a federal court.” Nat’l Farmers Union, 471 U.S. at 857, 105 S.Ct. 2447. A federal court must give the tribal court a full opportunity to determine its own jurisdiction, which includes exhausting opportunities for appellate review in tribal courts. Iowa Mut. Ins. Co. v. LaPlante, 480 U.S. 9, 16-17, 107 S.Ct. 971, 94 L.Ed.2d 10 (1987); see also Selam v. Warm Springs Tribal Corr. Facility, 134 F.3d 948, 954 (9th Cir.1998) (holding that the district court properly required exhaustion, including tribal appellate review, before entertaining an ICRA habeas petition).
Exhaustion is prudential; it is required as a matter of comity, not as a jurisdictional prerequisite. Strate v. A-1 Contractors, 520 U.S. 438, 451, 117 S.Ct. 1404, 137 L.Ed.2d 661 (1997); LaPlante, 480 U.S. at 16 n. 8, 107 S.Ct. 971. Exhaustion is not required where “the action is patently violative of express jurisdictional prohibitions,” Nat’l Farmers Union, 471 U.S. at 856 n. 21, 105 S.Ct. 2447, or it is otherwise plain that the tribal court lacks jurisdiction over the dispute, such that adherence to the exhaustion requirement would serve no purpose other than delay. Nevada v. Hicks, 533 U.S. 353, 369, 121 S.Ct. 2304, 150 L.Ed.2d 398 (2001); Strate, 520 U.S. at 459-60 n. 14, 117 S.Ct. 1404. Likewise, exhaustion is not required “where an assertion of tribal jurisdiction is motivated by a desire to harass or is conducted in bad faith ... or where exhaustion would be futile because of the lack of an adequate opportunity to challenge the court’s jurisdiction.” Nat’l Farmers Union, 471 U.S. at 856 n. 21, 105 S.Ct. 2447.
Boozer argues that he need not exhaust tribal court remedies because it is plain that the tribal court lacks jurisdiction under ICWA’s jurisdictional provisions and because exhaustion would be futile.
Boozer’s argument that the tribe clearly lacks jurisdiction under ICWA is without merit. ICWA provides:
An Indian tribe shall have jurisdiction exclusive as to any State over any child custody proceeding involving an Indian child who resides or is domiciled within the reservation of such tribe, except where such jurisdiction is otherwise vested in the State by existing Federal law. Where an Indian child is a ward of a tribal court, the Indian tribe shall retain exclusive jurisdiction, notwithstanding the residence or domicile of the child.
25 U.S.C. § 1911(a) (emphasis added). Boozer argues that even if K.W.B. resides on the Colville reservation, there is plainly no jurisdiction in the tribal court, because she is legally domiciled in Georgia.3 By so

Boozer also suggests that K.W.B. did not “reside” on the reservation for statutory purposes, because at the time the district court proceedings were instituted she lived there as a result of the tribal court order. We do not decide whether K.W.B. in fact “resides” on the reservation within the meaning of the statute. We conclude only that it is not frivo*936lous to maintain that she did reside on the reservation at the pertinent lime.
