Are international students at a disadvantage?

<p>I am from Brazil, where not many students are willing to study in the U.S. I did some research and found out that actually Brazilian students are exclusive to ivy-leagues (other colleges either do not have any brazilian students or have less than 5 of them per year).
Considering this fact, I ask: do I as a Brazilian have more chances of being accepted for a very selective university than a Pakistani or Chinese, for example, who represent a huge amount of international students in the U.S.?
I plan to apply to Georgetown, Johns Hopkins, Tufts, George Washington University, University of Virginia and American University. I will not apply to the ivies.
Thank you!</p>
