USCIS regulations state that on-campus employment is automatically authorized (no special work permission necessary) for any student in lawful F-1 or J-1 status. On-campus employment is limited to 20 hours per week while school is in session, but may be full-time during vacation periods.
Type 1: Employment by Princeton
Work performed on campus in a student's academic department, the library, the computer center or the housing office is acceptable. Work required by a scholarship, a fellowship or an assistantship is also acceptable. Generally, students work on campus provided that payroll is distributed from a Princeton account.
Type 2: Other employment on Princeton premises
Work performed on campus (on Princeton's grounds or premises) for an outside contractor or firm may be considered on-campus employment if the employer provides direct services (i.e. bookstore, dining services, etc.) to students.
Social Security Number
