With regards to student visas, should a visa be required for entry into Canada, Students should apply through a Canadian embassy close to their residence.  As it relates to returning back into the United States on their student visa, in addition to their valid student visas, they will need the following:

•  A SEVIS Form I-20, endorsed for travel and signed by their DSO

•  A current passport valid for at least six months after the date of re-entry

Students should consult their Designated School Official (DSO) prior to traveling. The DSO generally works in the International Student Office. They must have a current SEVIS Form I-20 endorsed for travel and their DSO needs to be able to verify that their SEVIS record is accurate and up-to-date.
