Frequently Asked Questions:
Traveling on F-1 and J-1 Visas

How often should the back of my I-20 be endorsed?
Your I-20 should be signed by one of the Responsible Officers (RO), Alternate Responsible Officers (ARO) or Designated School Officials (DSO) in order for you to re-enter the U.S. after you travel outside the U.S. The signature is valid for re-entry for up to six months from the signature date or until the completion date indicated on the I-20, whichever comes first. (Please note that if you remain out of the U.S. for more than five (5) months, you will need to request a new I-20 for re-entry).
For students who have graduated and are on post-completion practical training, the signature is valid for six months only.

I have a newly reissued passport. While I am in the United States, is it possible to change my valid visa stamp from my old passport to the new one?
No. However, you may get a new visa stamp in your newly issued passport from the U.S. Consulate/Embassy in your home country.

I recently graduated. I would like to travel back to my home country for a vacation, and then return to the United States to work under Optional Practical Training. Do I need to request an Employment Authorization Document (EAD) prior to my departure? Yes. Optional Practical Training must be applied for prior to completion of studies. In order to re-enter the United States, you will need the following documents:
   1) Valid passport
   2) Valid visa stamp
   3) SEVIS I-20 with endorsement for Optional Practical Training
   4) Valid EAD

What happens if the visa stamp in my passport expires while I am still in the U.S.?
The visa stamp in you passport is an "entry permit" only, so you need not be concerned if it expires once you have already entered the U.S. However, if you plan to travel out of the U.S. and re-enter, you will need to go to the U.S. Consulate (preferably in your home country) and apply for a new visa stamp. When you go to the Consulate to apply for the new visa stamp, you should bring with you a newly issued SEVIS I-20 (if you are a student in F-1 status). It is also strongly recommended that you provide proof of sufficient funding to cover you tuition and living expenses, and a letter from your advisor stating that you are in good standing and making adequate progress toward your degree. An official transcript and proof of your close ties to your home country are also recommended.
