目前全美的印第安人部落“国”（nation），超过326个，他们在所在地自治，不受所在州的管辖，
An Indian reservationis an area of landheldand governed by aU.S. federal government-recognized Native American tribal nation, whose government issemi-sovereign, subject to regulations passed by theUnited States Congressand administered by theUnited States Bureau of Indian Affairs, and not to theU.S. state governmentin which it is located. Some of the country's 574[3]federally recognized tribesgovern more than one of the 326[1]Indian reservations in the United States, while some share reservations, and others have no reservation at all. Historical piecemeal land allocations under theDawes Actfacilitated sales to non–Native Americans, resulting in some reservations becoming severely fragmented, with pieces of tribal and privately held land being treated as separate enclaves. This jumble of private and public real estate creates significant administrative, political, and legal difficulties
