Can You Work Part-Time on OPT?
Quick Answer
Yes, you can work part-time on post-completion OPT, but your position must require at least 20 hours per week to count as valid employment. Part-time work that meets this threshold stops the unemployment clock, and the job must be directly related to your field of study as listed on your I-20.
Key Takeaway
Part-time work of 20+ hours per week in your field of study counts as valid OPT employment and stops the unemployment clock.
Part-Time Employment Rules on OPT
Under USCIS regulations, F-1 students on post-completion Optional Practical Training are permitted to work part-time, defined as a minimum of 20 hours per week. This is a critical threshold because any employment below 20 hours per week is not considered valid employment for OPT purposes, meaning your unemployment days will continue to accrue even if you are technically working.
The 20-hour minimum applies to each individual position. If you hold a single part-time job that meets the 20-hour requirement, you are in compliance. If you hold multiple part-time positions that individually fall below 20 hours but collectively exceed it, each position should still be reported to your Designated School Official (DSO), though USCIS guidance generally requires at least one qualifying position at 20+ hours.
Your part-time employment must be directly related to your major field of study as indicated on your I-20 form. USCIS does not require that the job title match your degree exactly, but there must be a clear and demonstrable connection between the work you perform and the academic discipline you studied.
- Minimum 20 hours per week required for valid OPT employment
- Job must be directly related to your field of study
- Report all employment to your DSO within 10 days of starting
- Part-time work stops the unemployment clock
- No prior USCIS approval needed to start part-time work
Working fewer than 20 hours per week does not count as employment for OPT purposes. Your 90-day unemployment clock will continue running.
How Part-Time Work Affects the Unemployment Clock
One of the most important aspects of post-completion OPT is the unemployment limit. Standard OPT holders have a maximum of 90 days of unemployment, while STEM OPT extension holders receive up to 150 days total. Part-time employment of 20 or more hours per week is treated the same as full-time employment for purposes of stopping the unemployment clock.
This means that if you secure a qualifying part-time position, your unemployment days stop accruing from the date you begin working. If you later lose that position or reduce your hours below the 20-hour threshold, the clock resumes. Tracking your unemployment days carefully is essential because exceeding the limit can result in a violation of your F-1 status.
It is highly recommended to keep detailed records of your hours worked, including pay stubs, timesheets, and offer letters, in case USCIS or your DSO needs verification. Using a tool like TrackMyOPT can help you monitor your unemployment days in real time and avoid accidental violations.
Reporting Part-Time Employment to Your DSO
Whenever you begin a new part-time position on OPT, you are required to report the employment to your DSO within 10 days of the start date. The information you need to provide includes your employer's name and address, your job title, the start date, and whether the position is full-time or part-time. Your DSO will update your SEVIS record accordingly.
If you are on STEM OPT, you will also need to update your employment information through the SEVP Portal directly. STEM OPT has additional reporting requirements, including the I-983 Training Plan, which must be completed with your employer. Even for standard OPT, timely reporting is critical because failure to do so can jeopardize your immigration status.
