F- 1 visa refers to the non-immigrant visa issued by the US consulate to foreign students who want to study full-time in American academic institutions. This visa allows international students to live in the United States as students, but at the same time requires students to attend more than 80% of the courses in one semester and meet certain credit requirements. They are not allowed to work in commercial companies, enterprises and organizations in the United States to get wages.
