<p>I would check with colleges or people who know more about the situation, because I am almost 100% certain the information you are being giving here is incorrect.</p>
<p>I was not yet a citizen when I applied to college, but my parents and I had green cards. Unless something has changed since then (it’s always good to double-check), you will be considered the same as a U.S. citizen for admission, aid, etc. This is exactly how it was for me and any other people I knew who had green cards/were permanent residents (it IS different if you are not a permanent resident). There is not way you will be considered international/placed in that pool if you have a green card.</p>
