For US universities, is the post-study work permit duration two years if the course is STEM?
No, it is three years, not two. Every F-1 graduate gets 12 months of standard OPT. STEM-designated degrees add a 24-month extension, for 36 months total. You need an E-Verify employer, a signed Form I-983 training plan, and you must file the extension before your initial 12 months expire.
No, it is three full years, not two. Your total post-study work window on an F-1 visa combines a standard 12-month OPT period with a 24-month STEM extension, but only if your degree sits on the official DHS STEM list and you meet a short set of extra requirements.
How Your 36 Months Break Down
| OPT Stage | Duration | Who Qualifies |
|---|---|---|
| Standard OPT | 12 months | Every eligible F-1 graduate |
| STEM OPT extension | 24 months | DHS STEM-designated degree holders only |
| Total combined | 36 months (3 years) | STEM graduates who meet extension requirements |
Requirements for the 24-Month Extension
- Your employer must be enrolled in the US government's E-Verify program.
- You and your employer must complete and submit a formal Form I-983 training plan.
- You must file your extension application before your initial 12-month standard OPT period expires.
My Advice
Confirm your exact degree's CIP code against the official DHS STEM list well before graduation, and start the Form I-983 conversation with your employer at least 90 days before your standard OPT expires so your extension filing does not slip past the deadline.
