Thanks for the tips. I did do the usual google search/visit websites of schools kind of things.
One more question: based on my profile, would you say that the schools I am considering are schools I am likely to be selected at? I am asking because I have seen many international students profiles on this forum, who have good grades and GREs and did not get into most of the places they have applied to. Since Rochester and Arizona are top in optics, with my profile, what would my chances (roughly) be?
