During this season, many students are traveling. On top of making sure you have a valid travel signature, SEVIS has now released a new set of recommendations of documents that you might consider bringing with you on your travels that might help you avoid any problems upon your re-entry to the United States.
Some of the documents you might consider having with your signed I-20 and valid F-1 visa when you return to the US are:
Proof of financial support
Evidence of acceptance to your school, like a recent tuition payment receipt or acceptance letter
Proof of paying the I-901 Student and Exchange Visitor Information System (SEVIS) fee
Safe Travels!
