Choctaw Nation Membership

The CDIB card is a federal government card certifying an individual's blood degree and tribe.  The CDIB is approved and signed by a Bureau of Indian Affairs representative once they establish the individual is a descendant, by the blood of a Dawes Enrollee.  The Tribal Membership Card establishes an individual as a member of the Choctaw Nation of Oklahoma and can only be issued once a CDIB has been approved.
