TRAVEL OUTSIDE THE U.S.
If you are leaving the U.S. on an emergency or on vacation and plan to return to the Diablo Valley College to continue a course of study, you must have your I-20 endorsed (signed) for reentry into the U.S. before you leave. If you fail to do this, you will have trouble reentering the U.S.
The authorization for re-entry is the required signature on page 3 of your I-20. You must submit your I-20 at least one week prior to your date of departure to the ISAS office. DO NOT WAIT UNTIL THE LAST MINUTE OR WE MAY NOT BE ABLE TO SIGN IT IN TIME. If you have to leave immediately and cannot wait please send us the I-20 and we will mail it to your address outside of the US.
Also, please check out helpful links for airport security, status and more.
