What to do to calm north American Indian heritage for benefits to go back to school?
First you need to do some basic genealogy, tracing yourself to your parents, grandparents, etc all of the way to the person you believe to be an American Indian. You need to determine which tribe that person was a part of and contact that tribe directly. The tribe will let you know whether or not your ancestor is listed on their base roll. Assuming they are listed on the base roll, you would then have the proof you are seeking. You then must become enrolled in the tribe in order to qualify for tribal funding or other funding reserved for American Indians.
