<p>Bear in mind that as a US citizen, you will not be considered an international for US university admissions (as some people seem to be implying). Also, overseas international schools (especially the American schools) send many, many kids to US universities every year. They are, in general, very knowledgeable about the application process. There is a big difference between being an American citizen who happens to attend an International HS in China and a Chinese citizen who tries to apply to a US university. </p>
