F1 students are only allowed to work on campus. Working off campus is illegal and grounds for termination. During the fall and spring semesters students can only work up to 20 hours a week, but during the summer students can work up to 40 hours a week.
To find work on campus, go around to different departments and ask if anything is available. You can also read the Career Services web page. https://web.saumag.edu/career-services/
