As long as it takes the student to finish his or her course of study the F1 visa is valid for. Work on campus and in some situations even off campus is allowed for F1 visa holder students. Eligibility to apply for employment-authorized practical training after the completion of their academic program is applicable for student visa holders. This training is usually limited to twelve months but may be extended to as much as 29 months for students who are pursuing a degree in science, technology, engineering, or mathematics. F1 visa students are able to transfer schools and change their focus of study while pursuing a degree in the U.S. Once they have completed their course of study or practical training (if applicable), they have sixty days in which to depart the U.S.
