Tribal Government Services (CDIB/Citizenship)

Tribal government services (TGS) provides Certificate of Degree of Indian Blood (CDIB) cards, Chickasaw Citizenship cards and information to Chickasaws who are direct descendants of enrollees listed as "Chickasaw by blood" on the Final Approved Rolls of the Dawes Commission.

A CDIB card must be issued before a Chickasaw citizenship card may be obtained. The CDIB card is issued by the Bureau of Indian Affairs. A Chickasaw citizenship card is issued by the Chickasaw Nation and opens the door to tribal programs and services.

Completed applications containing all required and/or requested documents are processed in the order received by TGS. Due to the varying number of applications received on a daily basis and the uniqueness of each, there is not a standard processing timeframe. Applicants may call TGS for a status check at any time.
