Oh, and if you are asking about scholarships for medical school, most schools usually have a small handful that they offer out to only the most competitive students that they have admitted (maybe 5-20 offers at most).
There are not many other medical school scholarships however. The Daughters of the American Revolution (DAR) offer two types of awards to medical students, each for $5000/yr for 4 years, but United States citizenship may be a requirement. The Jack Kent Cooke Foundation has a general graduate school scholarship program that awards about 35 scholarships for full tuition and a stipend for up to 6 yrs of study for which students entering medical school are eligible. However, that may also require United States citizenship.
Other scholarships have to be found through searches, like using http://www.fastweb.com. Your country may offer special scholarships to attend school in the United States or your country’s embassy in the United States may have a scholarship program. Federal financial aid is only available to United States citizens.
