Authorization May Not be Rescinded

Once authorization to engage in OPT is granted, it may not be rescinded or canceled. This means that after OPT is authorized by USCIs, it is impossible to have it cancelled and restored at a later date. If you do not use the work authorization it will be forfeited.

Change of employer After OPT has been Authorized

You must report any change of employer or employer address within 10 days. Address changes can be reported to the International Affairs Office by emailing . If you change your employer, you must request, complete, and submit to IAO a new STEM OPT Extension Form as well as a new I-983 Training Plan and the final evaluation report from your old I-983. SEVIS will be updated and you will receive a new I-20 from the International Affairs Office. Directives regarding pick-up of the new I-20 will be provided by the International Affairs Office.

Social Security and Other Taxes

In general, F-1 students who have been in the U.S. fewer than five tax years are “nonresidents for tax purposes” and are exempt from Social Security (FICA) and Medicare taxes. However, your earnings are subject to applicable federal, state, and local taxes. Beginning in the sixth year, most students become “residents for tax purposes” and employers should withhold Social Security and Medicare taxes. Tax returns must be filed on or before April 15 each year for the previous calendar year, for both “nonresidents” and “residents.”

Traveling Outside of the U.S. While on OPT

Reentry provisions of the regulations require students who have graduated and are on authorized OPT to present the following documents to reenter the U.S.:

  • STEM OPT I-20 signed on page 2 by the IAO DSO, within the last twelve months. Should you require an updated travel signature and are no longer in Philadelphia, email or phone the International Affairs Office for directives.
  • Valid Employment Authorization Document (EAD)
  • A valid passport
  • A valid F-1 visa stamp
  • A job offer letter or proof of employment. F-1 regulations allow for travel and reentry in order to “resume employment.”
  • Dependent Travel: Dependents do not receive an EAD. An F-2 dependent must carry copies of the F-1 student’s I-20 with OPT recommendation, EAD card and job offer letter, in addition to the F-1 I-20 when traveling.
  • Travel during the “cap gap” period may not be possible if the EAD has expired.
  • Travel while on OPT carries some risk. This risk increases for individuals on OPT if the F-1 visa has expired and a new one is required to reenter the U.S. or if the F-1 student has been unemployed for more than 150 days. Be sure to contact the IAO when considering travel outside the U.S. and reentry to continue OPT.

Employment Authorization with a Pending H-1B petition (“Cap Gap” employment authorization)

  • All students on OPT who have a pending or approved H-1B petition with a request for change of status will have their F-1 status and OPT authorization automatically extended if the employer has filed a timely H-1B petition with a change of status request with a requested October 1 start date.
  • If your employer requires a new Cap-Gap I-20, contact the International Affairs Office.
  • The OPT employment authorization automatically ends if the H-1B petition is denied, rejected, or withdrawn (a student may continue working until the end date indicated on the OPT EAD. The F-1 has a 60 day grace period with no work authorization after the end of OPT.

Important Facts to Remember about STEM OPT Extension

  • Students granted a 24-month OPT extension may not accrue an aggregate of more than 150 days of unemployment dating back to the start of the initial post-completion OPT 12-month period.
  • A student meeting the eligibility requirements for a 24-month extension may request an extension of employment by filing Form I-765 90 days prior to the expiration date of the student’s current OPT employment authorization.
  • The student seeking the 24-month extension must properly file the I-765 with USCIS within 60 days of the date the DSO recommends OPT in the SEVIS system.
  • Students may not be their own (sole) employer or provide employer attestations on their own behalf. Additionally, there must be an employer-employee relationship with the employer providing training on site, which means that the student is employed directly by the company, not employed by a third party or temporary employment agency. The government regulation states that “the employer that signs the I-983 Training Plan must be the same entity that employs the student and provides the practical training experience.”

To qualify for STEM OPT Extension, the position must be full time (20+ hours per week). Employment with multiple employers is only possible if both positions will be more than 20 hours per week and if both employers comply with all of the STEM OPT regulations, including completing and signing the I-983 Training Plan.
