Make sure you spell everything exactly right and write clearly all your information.... because if you spell it wrong, or mess up a number, or check black when you mean white...(or vice versa).....you will live with that information to the end of your days without being able to change it short of an Act of Congress, Presidential Order, or UN resolution...
I still have this vision of some poor black guy or white guy getting asked "what tribe?" for the rest of his life... after checking Native American instead of native born citizen...
And my blonde 16 year old hair, became forever brown on whatever form of official identification, I had from 1984 to today...luckily what isn't gray is actually brown today.
