International students at prep school

<p>I am curious about something. There are a lot of international students at elite boarding pre schools like Exeter, Choate, Deerfield ect whose parents send them to these schools in the hope that they get accepted to the ivy league. I imagine that the ivy league wants them over other international students as they are educated at top American schools and most dont need financial aid. At elite prep schools there are a significant number of students especially from China, Hong Kong, Korea ect. Does anyone know if these international students have an advantage even over non international students from the same schools?</p>
