<p>First of all, you’re in a dilemma that almost all of the college-crazy kids on this site would kill for. :)</p>
<p>Moving forward. Mark whichever you feel most comfortable with; do you identify yourself as Native American? Have you done so for the majority of your lifetime? If so, mark both. If you’ve always identified as being solely Hispanic, mark only Hispanic. Either way, you’re still a URM, so in this special case, you can’t lose.</p>
<p>Best of luck!</p>
