As far as being Native American, I grew up in an area nestled between three reservations...(so I kinda have an idea) They get tribal ID cards. If I'm not mistaken, each reservation is considered to have it's own governing body. I wish I knew more actually.

And lastly, white people get "a little help" getting into educational institutions?! Since when!? Not snarky-just....really shocked.

Edit...as a little bit of trivia, tribes issue their own license plates. Folks not from the area might assume it's a plate from Canada or some far off place.
