F-1 and M-1: Student Visas
The F-1 Visa is for students attending a full-time degree or academic program at a school, college or university. The F-1 Visa is valid for as long as it takes the student to finish his or her course of study. An F-1 Visa also allows students to work on campus and in some situations even off campus.
The M-1 Visa is for students enrolled in non-academic or "vocational study". The M-1 Visa is valid for one year, but students may apply for extensions for up to three years.
