<p>Race and ethnicity for college admissions are based on self-identification. HOWEVER, the NA category is different from the other racial and ethnic categories, it is the ONLY one that asks for some kind of proof of identity (enrollment #).</p>
<p>The race question asks you to mark all categories that apply, so yes, to be honest you should be marking AI/NA and whatever other race(s) you are.</p>
<p>In the admissions process, you will be placed in the AI/NA pool of candidates even though you are of mixed race.</p>
