It is prudent to consult an ISSS advisor prior to leaving the US as immigration regulations can change at any time.  

Currently the following are required to return to the US:

  • A valid passport

  • A valid F-1 visa stamp in your passport (citizens of Canada and Bermuda EXEMPT)

  • Your OPT I-20 endorsed for reentry by an ISSS advisor 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 US while your OPT application is pending with USCIS, you should consult an ISSS advisor before traveling abroad. 

We recommend that you remain in the US while OPT is pending at USCIS to respond to any additional requests from USCIS.  For more information read here.

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