For international applicants, only a handful of top 50 colleges claim to be need-blind in admission and also meet 100% of demonstrated financial need.

However, that doesn’t necessarily mean more of them won’t offer generous need-based aid if they admit you. When a school’s Common Data Set shows “100%” in section H2(i), I’d like to assume that percentage applies to all enrolled students, including internationals. The average FA packages for admitted international students who receive them do seem to be quite high for many T50 private colleges.
