Information about traveling after your initial OPT has ended and the STEM Extension period has begun.
While the application is pending:
OGI recommends avoiding travel while your OPT is pending if your current OPT period has expired as it might be more difficult to reenter with an expired document. Additionally, USCIS might send you a Request for Further Evidence (RFE) while you are abroad to your U.S. address which requires answering as soon as possible. If your STEM OPT is approved while you are outside the U.S. you will be required to have your EAD in hand to reenter the country. USCIS cannot mail your EAD outside of the U.S.
After STEM OPT is approved:
In order to reenter the US after travel abroad, you must have:
STEM OPT EAD in hand
I-20 with a valid travel signature
Valid passport
Valid F-1 visa
Letter or proof of employment.
*Travel signatures are only valid for 6 months while on OPT.
If you exceed your 150 days of unemployment while outside the U.S., CBP can deny your reentry at the border, even if you have all of the documents listed above.
