USA OPT and STEM OPT Explained
Turn your F-1 degree into up to three years of US work experience
What OPT and STEM OPT Are
Optional Practical Training (OPT) lets F-1 international students work in the US in a role directly related to their major, typically for up to 12 months after completing a degree. For Indian students, OPT is often the crucial bridge between graduation and a longer-term work visa.
If your degree is on the government's STEM designated list, you may apply for a 24-month STEM OPT extension, bringing your total practical training to up to three years. That extra time is valuable because it gives more chances to be selected in the H-1B lottery.
OPT vs STEM OPT at a Glance

|---|---|---|
| Duration | Up to 12 months | Additional 24 months |
| Eligible degrees | Most F-1 degree programs | Only STEM-designated majors |
| Employer requirement | Job related to your major | Employer must be enrolled in E-Verify |
| Training plan | Not required | Formal training plan (Form I-983) required |
| Unemployment limit | Limited days allowed | More total days across OPT and extension |
Exact rules, day limits, and forms are set by USCIS and can change — always confirm current requirements with your Designated School Official.
Timing, Cap-Gap and Getting It Right
OPT is time-sensitive. You generally apply through your Designated School Official (DSO) and USCIS within specific windows around your program end date, and you cannot start work until your Employment Authorization Document (EAD) is approved. Applying late or incorrectly can cost you months of work eligibility.
Cap-gap relief can extend your F-1 status and, in some cases, work authorisation if a timely H-1B petition is filed and selected while you are on OPT, bridging the gap until the H-1B start date. The details are strict, so coordinate closely with your DSO and employer.
Every day of unemployment on OPT counts against a strict limit, and exceeding it can end your status. Line up employment early, keep records that show your job relates to your major, and file all applications within the required windows.
