Travel While OPT Application is Pending:[align="left"]According to Student Exchange Visitor Program’s guidance, students participating in post-completion OPT may travel abroad while the OPT application is pending. However, travel during this period of time should be undertaken with caution for the following reasons:[/align]

1. If a request for more evidence (RFE) is issued by USCIS: An RFE requires immediate attention by the applicant.
2. If the application is approved while the applicant is abroad, the student will be required to present the EAD upon return.
   

[align="left"]Students who decide to travel while the OPT application is pending are highly discouraged from leaving the U.S until the application has been received by USCIS and the I-797 receipt notice has been issued. Students should bring the receipt notice with them as proof that an application has been submitted. Although the receipt notice is a good substitution, admission into the U.S. is up to the discretion of the CBP officer, and there have been reports of students without their EAD work permit having problems at the port of entry.[/align]

[align="left"]We recommend that you avoid international travel before your OPT is approved. If there is a problem with your application USCIS will mail you a Request for Evidence (RFE) to your U.S. address. Even if a friend is checking your mail, you may have difficulty responding to the RFE in time. If you have to travel, you will need the following items when you return to the U.S.:[/align]

✓	Unexpired passport
✓	Unexpired F-1 visa (except for Canadians)
✓	I-20 with OPT recommendation and an unexpired travel signature (signature valid for six months when on OPT)
✓	I-797 USCIS receipt notice of your OPT application
✓	If you have a job offer or interview appointments set up, bring a job offer letter or communication about interviews with you
