<p>@soaroneagles. You can register as a member (minor) of the Choctaw Nation under age 18. All 3 of my children are registered. Your direct line ancestors must also register if still living. My oldest dd is 17 and just got her adult membership card this week. Now she is fully enrolled and has a number for the college application. There is no blood minimum for the Choctaw Nation of Oklahoma.</p>
