How the ADCOM segregates you!

<p>This is just a question:</p>

<p>lets say for example,</p>

<p>there is a student born in Asia that studied in various countries (mostly NAmerica) and is now studying in S.America and is applying from S.America?</p>

<p>What POOL is this applicant thrown into during the ADCOM process? Any disadvantages?advantages?</p>

<p>is he still considered an asian and thus compared against only asians????</p>
