Emory is a quite generous school for Chinese students, I've never heard that she will not offer at least 50% of tuition dollars for Chinese. And Atlanta is a great city, and is always ranked quite high in terms of city living standard, and natural environment.
as far as i know, simon shcool will give every chinese students scholarship, at least 20%; but the location is not so good, 5 hr to NYC. extremely cold, but if you stay at apt. and school, it is not so bad
