Please Note

  • A STEM degree obtained at a US university prior to a student's current degree may be the basis for a STEM extension. 
  • If a STEM student receives a 24-month extension, the limit on unemployment is no more than 120 days, applied to the entire 36-month period of post-completion OPT.
  • Employment authorization is automatically extended while a timely-filed 24-month OPT EAD extension is pending until the new EAD is received or for 180 days, whichever is earlier.  
  • The employment authorization period for the 24-month OPT extension begins on the day after the expiration of the initial post-completion OPT employment authorization and ends 24 months thereafter, regardless of the date the actual extension is approved.
  • The 24-month extension is allowed twice per lifetime. Each extension must occur after a higher degree level has been completed. 
  • The extension is only for those in Post-completion OPT employment.
  • A student may change employer during the 24-month extension; however, USCIS advises against changing employers while the I-765 is pending, since the I-765 names a specific employer.
