A US education is very expensive. Tuition, room and board at an undergraduate institution will cost from $15,000 to $40,000 a year, depending on the school. A graduate education can be even more expensive. As a result, international students will find very little information about financial aid for international students. This site presents more information about financial aid for international students than any other publication. You will find a description of how to access what aid is available, and a discussion of some of the problems you may encounter as you pay for a US education.
You will undoubtedly encounter several scholarship matching services that, for a fee, will offer to search a database of scholarships for awards that match your profile. Don’t waste your money on such services.
