What are the restrictions concerning on-campus employment?
F-1 visa holders who are registered as full-time students may work no more than 20 hours per week on-campus during the regular academic year (Fall & Spring Semesters). Registered F-1 students do not require authorization from the USCIS for on-campus employment. However, full-time (more than 20 hours per week) of on-campus work is allowed during breaks between semesters (i.e. summer, winter and spring breaks) if the student has otherwise been maintaining status.
