F-1 Employment Options

Working on campus is permitted, but during the fall and spring, on-campus employment is limited to twenty hours per week.

Important Note: If you are taking classes in the summer, it is best not to work full-time while your class is in session. Even though summer is typically a vacation term for the university, if you are enrolled in classes, a strict interpretation of on-campus employment regulations indicates that you should limit your work to 20 hours while class is in session. This is particularly important if you are graduating at the end of summer since the U.S. government likely considers your graduation term an academic, not vacation term. You must also stop working once your program is complete.

Working off-campus ALWAYS requires written permission, either from an OIPS advisor on your I-20 (p. 2) or from the US Citizenship and Immigration Services (USCIS).  Never work off-campus, even for a few days, until you have the written permission you need.

Employment Timeline

Some exceptions may apply.  Schedule an appointment with an OIPS F-1 advisor to discuss your situation.

* The length of OPT is 12 months for each level of study. If you engage in pre-completion OPT, your eligible period of post-completion OPT will be reduced by one month for every two months of part-time pre-completion OPT that is worked when you graduate. For example, if you engage in four months of part-time pre-completion OPT, you will remain with only 10 months of post-completion OPT.
** The 24-month STEM OPT Extension is for students who majored in designated Science, Technology, Engineering, and Math (STEM) degrees approved by DHS. This type of OPT is a 24-month extension of OPT.
