Does anybody know info about scholarships for international students in the U.S?!

Nowadays, most of the universities are having provisions for scholarships or financial aids. These scholarships help a student by lowering the cost of studies. But then it's very important to know in which field you want to pursue your education. Actually my sister has just completed grade 12, and wanted to make a career in health care field. I came across a good site on net while searching for best scholarship programs for students.
