Why don't you get on their website and ask them those questions or do the research on the website? Stanford is a good college and located in CA where lots of Chinese lived in the nearby cities, but I don’t know if they offer any scholarships to foreign students, the tuition will be more for non-citizens than for citizens, here in the Midwest, it is about 7,500 a semester for foreign students.
i cannot answer u stanford has lots of chinese or not. but it is hard for u to go in. it is a top university in south california, U.S.Your GPA better have 4.0 and the SAT 1&2 have 1900 or higher. they will see ur TOFUL also if u are immigrant
