Chance for international student living in the US (Stanford, MIT, Harvard, Penn, Cornell, Duke, ...)

As is Harvard, Yale, and Princeton. There are only six schools in the US that are both need-blind for all applicants, and who guarantee full-need for four years (MIT, Harvard, Yale, Princeton, Dartmouth, Amherst). There are others that are need-blind but not full need (such as Boston University) and other that are need-aware but full-need (such as Columbia).
