To be a bit nit picky: There are a few universities that meet full need for international students but that are not need blind for admissions – it is hard to get admitted to these if you need full financial aid. However, it is not clear that they are any more difficult to get accepted to compared to the schools that both meet full need and are need blind.
The tiny handful of schools that both meet full need and are need blind are all exceptionally difficult for admissions. “Top student in your high school” is a start but is not likely to be enough for any of them as an international student.
Otherwise I agree completely with @austinmshauri and the other comments above. The best aid is generally given by the schools. Given how expensive university is in the US, finding enough financial aid to fully fund your education here is going to be tough.
