<p>Colleges limit the number of foreign students from each country to maximize international diversity (i.e they’d rather have a 100 students from 30 different countries, rather than 100 students from 3 different countries), so it is advantageous to be from an under-represented country, like Burkina Faso or Lichtenstein. If you are applying from China, India or SKorea, you are competing against your countrymen in a very crowded field.</p>
<p>FYI: stats on international students
