I agree that there are really no safety schools for international students who need full financial aid.
I agree. There are only seven colleges that are both need blind for admissions AND guarantee to meet full need for all accepted international students. They are:
Amherst College
Harvard University
Bowdoin College
Massachusetts Institute of Technology
Princeton University
Dartmouth College
Brown University plans to join this list in 2025.
This list above is highly competitive with admissions for international students in the single digits.
At the other colleges that meet full need for all admitted international students, your level of financial need will be considered when your admission is considered as they are need aware.
You might hit the lottery jackpot and get accepted at one of the schools on your list with enough aid to attend, but this cannot be counted on…at all.
I hope you have some sure thing colleges on your application list in your own country.
