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. During the school breaks in winter, spring and summer, you may work full-time.  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.

F-1 Employment Timeline

The employment timeline shows you when you may be eligible for certain immigration benefits.

Employment Timeline

* 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.

Erin’s Tip

Erin Dunleavy is an international student advisor in OIPS.  She is originally from Michigan and joined the OIPS team in 2009.

"I encourage you to explore the F-1 employment options (on-campus employment, CPT, OPT, etc.) BEFORE you meet with an OIPS advisor.  This will enable you to ask very specific questions during your appointment and maximize your opportunities at Mason.  If you do not know where to start, I advise you first review the web page Comparison of F-1 Employment Options.  This page gives you an overview of the different employment options, including eligibility requirements, advantages and disadvantages."
