How long can I work in the US on OPT after a STEM degree compared with a non-STEM degree?
STEM graduates can work in the US for up to 36 months on OPT: 12 months of post-completion OPT plus a 24-month STEM extension, available only for eligible STEM degrees. Non-STEM degrees get 12 months. That extra time helps you build experience for work visas such as H-1B.
