F-1 students approved for OPT based on a degree included on the STEM-Designated Degree Program List can apply for a 24-month extension of post-completion OPT (for a total eligibility of up to 36 months). 

To verify OPT STEM Extension eligibility, check that the CIP code major number listed on page one (1) of your I-20 document is listed on the STEM-Designated Degree Program List. STEM eligibility is determined by CIP code number, and not degree name. Please note that your degree name and your CIP Code Title may vary.

Please see the examples below and check your I-20 and the STEM list carefully!
