Native American land is controlled by tribal law. Tribal Law only applies to those who live on the Reservation. However, if you are carrying a firearm with a concealed firearm permit that is valid in the state the reservation is located in that permit may not be valid on the Reservation. If caught they will most likely take the firearm and tell you that you can go to Tribal Court to get it back. Some Tribes consider federal and state highways through their land as being under their control and say you cannot carry a firearm in a vehicle or on the roads on their Reservation. Tribal Police in most instances works closely with the Local Law Enforcement surrounding the Reservation. If you are breaking a state firearms law they will most likely hold you and contact the local authorities.
We recommend that before you carry a firearm on any Reservation ensure you contact the tribal leader and obtain permission in writing if possible. Otherwise, keep it unloaded and secured in your trunk or locked box in the back of a vehicle that does not have a trunk.
At present, there are 574 federally recognized American Indian and Alaska Native tribes and villages.
Approximately 56.2 million acres are held in trust by the United States for various Indian tribes and individuals. There are approximately 326 Indian land areas in the U.S. administered as federal Indian reservations (i.e., reservations, pueblos, rancherias, missions, villages, communities, etc.). The largest is the 16 million-acre Navajo Nation Reservation located in Arizona, New Mexico, and Utah. The smallest is a 1.32-acre parcel in California where the Pit River Tribe’s cemetery is located. Many of the smaller reservations are less than 1,000 acres.
Because the Constitution vested the Legislative Branch with plenary power over Indian Affairs, states have no authority over tribal governments unless expressly authorized by Congress. While federally recognized tribes generally are not subordinate to states, they can have a government-to-government relationship with these other sovereigns, as well.
Furthermore, federally recognized tribes possess both the right and the authority to regulate activities on their lands independently from state government control. They can enact and enforce stricter or more lenient laws and regulations than those of the surrounding or neighboring state(s) wherein they are located. Yet, tribes frequently collaborate and cooperate with states through compacts or other agreements on matters of mutual concern such as environmental protection and law enforcement.
