Travel and Re-Entry While in OPT Status

Items Needed to Reenter the U.S. – please see the OPT FAQ for issues related to traveling while in OPT status. Or while your OPT application is pending.

1. Valid passport and valid F-1 entry visa
2. Valid I-20 form endorsed by an OISS adviser within the preceding six months
3. Valid EAD and letter from employer showing temporary employment in the authorized field of study.

What about traveling abroad after I have completed my studies and while I hold practical training status? If you have completed your course of study and have received your USCIS authorization for practical training (your EAD card), you may travel abroad and re-enter the U.S. in F-1 status. You will need the following documents for your re-entry: (1) a valid passport, (2) a valid F-1 visa stamp in your passport, (3) the new SEVIS I-20 recommending optional practical training (4) your original practical training Employment Authorization Document (EAD) issued by the USCIS and (5) proof that you have a job in the U.S. appropriate for practical training and that you are returning to the U.S. to resume or start this employment. If you do not have all of these documents you should NOT travel abroad without first consulting an OISS advisor. (An expired F-1 visa can pose a problem; it may be difficult to renew your F-1 visa while you are on practical training.)

it seems you really can. btw, the info is from yale website. You may print it out and go to discuss with ur advisor again.
