F-1 status and travel: SEVIS, I-20, I-94, visas and reentry
How to keep F-1 status during school and OPT: your SEVIS record, I-20 travel signatures, I-94 records, visa renewals and interviews, reentry checks, and what to do if status is lost.
Start with the guides to your SEVIS ID and your school's DSO, since most status questions go through them. Read the travel signature and I-94 guides before any trip abroad. The reinstatement and SEVIS termination guides cover what to do if something goes wrong; talk to your DSO first.
