F-1 Visa
This is the most common type of student visa. If you wish to engage in academic studies in the United States at an approved school, such as an accredited U.S. college or university, private secondary school, or approved English language program then you need an F-1 visa. You will also need an F-1 visa if your course of study is more than 18 hours a week.

M-1 Visa
If you plan engage in non-academic or vocational study or training at a U.S. institution then you need an M-1 visa.
