Are you planning on going home for a holiday? The DSO/PDSO needs to validate your status on page three of your current SEVIS I-20 if you are traveling outside the USA anytime and want to return.
You MUST have you SEVIS I-20 signed BEFORE leaving the United States for vacation or any short holidays. Failure to do so may result in being denied readmission to the United States.
It is the YOUR responsibility to check the expiration date of their SEVIS I-20, Visa, and Passport. You are required to report to the International Student Center within 3 days of re-entry to the US. Failure to comply may result in automatic termination of student status.
Traveling outside the USA also includes Canada and Mexico. Bring your current I-20 to the International Student Center at least two weeks in advance of your trip so that it can be signed by your DSO/PDSO.
