Optional Practical Training (OPT) Extension for STEM Degree Holders: Information

NOTE: This information is for certain science, technology, engineering and mathematics (STEM) degree holders who are about to finish their regular
12 months of OPT and wish to request additional 17 months of OPT.

General Information

On April 8, 2008, the U.S. Department of Homeland Security (DHS) published the interim final rule that changes several key aspects of F-1 optional practical training. One of the key changes impacts certain STEM degree holders. Effective April 8, 2008, the 12-month limit on F-1 OPT may be extended by 17 months, for a total of 29 months, for certain STEM degree holders.

Eligibility Requirements

  • The F-1 student must be currently participating in a 12-month period of OPT, working for a U.S. employer in a job directly related to the student’s major area of study. 
  • The student must have successfully completed a bachelor’s, master’s, or doctoral degree in a field on the DHS STEM Designated Degree Program List.
  • The student must have a job offer from an employer registered with the E-Verify employment verification system at the time of application for the 17-month OPT extension. It is the student’s responsibility to ensure that his/her employer is registered with E-Verify.
  • The student has not previously received a 17-month OPT extension after earning a STEM degree.
  • The Designated School Official (DSO) at ISSS must recommend the 17-month OPT extension in SEVIS, after verifying the student’seligibility, certifying that the student’s degree is on the STEM Designated Degree Program List and ensuring that the student is aware of his or her responsibilities for maintaining status while on OPT.
  • The student who timely files a non-frivolous application for the 17-month OPT extension will be able to continue employment while the extension application is pending, until a final decision on the I-765 or for 180 days, whichever comes first.
  • Student must have a current OPT Reporting Form on file with ISSS, filed within 90 days after your OPT start date.  Note:  if you have not reported employment to ISSS we cannot guarantee that your application for a STEM extension will be approved by USCIS.

Employer’s Responsibility

The employer must agree to report the termination or departure of an STEM OPT employee to the Florida Institute of Technology International Student and Scholar Services (ISSS) via email (isss@fit.edu) or through any other means or process identified by DHS if the termination or departure is prior to the end of the authorized period of OPT. Such reporting must be made within 48 hours of the event. An employer shall consider a worker to have departed when the employer knows the student has left the employment, or if the student has not reported for work for a period of five consecutive business days without the consent of the employer, whichever occurs earlier.

Students are also required to make a validation report to the ISSS every six months starting from the date the extension begins and ending when the student’s F-1 status ends, the student changes educational levels at the same school, the student transfers to another school, or the 17-month OPT extension ends, whichever is first. The validation is a confirmation that the student’s name and address, employer name and address and/or loss of employment are current and accurate. This six-month validation report is due to the ISSS within 10 business days of each reporting date. Changes and validation reports should be made via email to isss@fit.edu.

Limited Periods of Unemployment to Maintain Status

During post-completion OPT, F-1 status is dependent upon employment. STEM degree holder granted a 17-month OPT extension may not accrue an aggregate of more than 120 days of unemployment during the total of 29-month OPT period.

Travel Information

It is prudent to consult an ISSS adviser prior to leaving the U.S. as immigration regulations can change at any time. Currently the following are required to return to the U.S.:

  • a valid passport
  • a valid F-1 visa stamp in your passport (except Canadian and Bermudian citizens)
  • your OPT I-20 endorsed for reentry by an ISSS adviser within the last six months
  • your valid EAD for OPT
  • evidence of employment such as a job offer or employment verification letter

If you do not have all of these documents listed above or plan to leave the U.S. while your OPT application is pending with USCIS, you should consult an ISSS adviser before traveling abroad. For more information, see: http://www.ice.gov/sevis/travel/faq_f2.htm.

Please note: Your EAD will have a notation “not valid for reentry to U.S..” This is printed on all EAD cards issued for OPT and simply means that the card alone is not sufficient for reentry to the U.S.

H-1B Cap-Gap Extension of Duration of Status (D/S) and OPT Work Authorization until October 1

Duration of F-1 status and work authorization will be extended for a student on OPT who is the beneficiary of a timely filed, non-frivolous H-1B petition requesting an employment start date of October 1 of the following federal fiscal year (October through September). The extension of duration of status and work authorization would automatically terminate upon the rejection, denial or revocation of the H-1B petition filed on the student’s behalf.

Special Notes

  • If you later decide not to mail your OPT STEM Extension application (Form I-765 plus supporting documentation) to USCIS for any reason, you must notify an ISSS adviser immediately so that we may timely cancel your STEM Extension OPT recommendation in SEVIS as well. Failure to inform an ISSS adviser that you are not applying for STEM Extension OPT can cause problems in the future.
  • Please email (isss@fit.edu) or fax (321) 728-4570 a copy of your STEM Extension OPT EAD card to ISSS immediately upon receipt.
  • While your STEM Extension OPT application is pending, we strongly advise you against changing the address listed on Form 1-765, as USClS has not been able to process change of address notifications properly. Changing your address while your application is still pending may result in filing a new STEM Extension OPT application with a new fee. We suggest to use the address of someone who can receive mail on your behalf—remember to put “c/o”, followed by the person’s name and address, on Line 3 of Form I-765. The U.S. Postal Service will not forward USCIS mail.
  • If you receive a Request for Evidence (RFE), please inform ISSS immediately.
  • Your STEM Extension OPT will be automatically terminated when you begin studying at another educational level or transfer to another school.
  • If you find any errors by USCIS on your OPT/EAD card, please inform ISSS immediately.
  • Immediately inform ISSS of any immigration status change.
