<p>So I'm Asian.</p>
<p>Is marking "Asian" or "Do not wish to specify" going to significantly impact my chances?</p>
<p>If so, choosing which one would better my chances?</p>
<p>There have been many discussions about this, but I don’t think that either has been concluded to be better than the other. If you are interested in the discussions, you can search to find them. In my opinion, you should just put what best describes you, so in this case, Asian.</p>
