Proving Native American heritage for college admissions typically involves providing documentation that verifies your ancestry. The type of documentation required may vary depending on the college or university you will be attending, but some common forms of proof include tribal enrollment card or certificate of degree of Indian blood (CDIB), census records, birth, marriage or death certificates and letters of verification. The process of proving Native American heritage can be complex and may require significant research and documentation. If you are unsure how to proceed, you may want to consult with your local Native American Tribe for verification.
