Travel signatures refer to the list of signatures on the third page of the I-20. Travel signatures are valid for one year and must be the signature of the Coordinator of International Services or another authorized Lasell College Designated School Official (DSO). For a list of Lasell College DSO's, please refer to the first page of this handbook.
All F-1 students are required to present an unexpired I-20 with a valid travel signature at the port of entry when returning to the U.S. from a trip outside the country. Travel signatures are typically valid for one year. However, for travel to Canada, Mexico, and adjacent islands, it is recommended that the signature be no older than six months. For F-1 students who are in a period of Optional Practical Training (OPT) following graduation, the travel signature is valid for only six months for travel to anywhere outside the U.S.
Documents Required to Re-enter the U.S. in F-1 Status after a vacation period outside of the U.S.:
1. A valid passport
2. A valid F-1 visa stamp (except for Canadian citizens)
3. A valid I-20 with a valid travel signature.
F-1 students on OPT should have a travel signature that is no more than six months old as well as their Employment Authorization Document (EAD) and a letter from an employer verifying that they have a job in the U.S.
