Can I travel outside the US while my OPT application is pending at USCIS?
Before graduation, for example over Spring Recess, you may travel outside the US prior to USCIS approval of your application, if you return to the US prior to graduation.
After graduation, OISS does not recommend travel outside the US prior to receiving OPT approval from USCIS. If you must travel outside the U.S. after graduation, but before you have been approved for your practical training employment, it is advisable to speak with an OISS advisor about the timing of your application and the date you list as the beginning date of the proposed employment. The beginning date selected is important because it has an impact on how early you can apply, thus how early you will obtain approval.
