F-1 Visa Stamp vs Status vs I-20 vs I-94: The Difference Every International Student Must Know
Your visa, F-1 status, Form I-20, and I-94 are connected but not interchangeable. Learn which document controls travel, admission, school records, and authorized stay.
Direct answer
The F-1 visa is a travel document used to request entry. Status is the legal classification you maintain inside the United States. The I-20 is the school's SEVIS eligibility and recommendation record. The I-94 records CBP's admission class and admit-until notation. An expired visa does not automatically end status inside the United States, but a valid visa does not excuse a status violation.
What You Should Know First
- Visa validity and authorized stay are different questions.
- The I-94 is the admission record; the I-20 supports the F-1 purpose and SEVIS record.
- Travel can turn a nonissue—an expired visa while maintaining status—into a visa-renewal problem.
The Four Documents, Four Jobs
A visa is issued by a U.S. consulate and normally matters when you travel to a port of entry. CBP then decides admission and creates the I-94. The school issues the I-20 through SEVIS, while status is maintained through enrollment, authorized employment, reporting, and other F-1 rules.
Because each document answers a different question, checking only the visa expiration date is never a complete status audit.
- Visa: may I travel to seek F-1 admission?
- I-94: how was I admitted and until when?
- I-20: what school/program/OPT record supports the classification?
- Status: am I complying with the rules after admission?
Three Common Scenarios
A student with an expired visa, valid I-20, D/S I-94, and properly maintained status may generally remain inside the United States, but usually needs a new visa after international travel. A student with a valid visa but terminated SEVIS record cannot rely on the stamp to continue studying or working. A student with a corrected I-20 should still verify that the I-94 from the last entry says F-1 and D/S.
When a record conflicts, identify the issuing agency before seeking correction.
Vinay's practical note
Save a one-page status snapshot after every entry and every new I-20: passport, visa, I-94, SEVIS ID, program dates, and work authorization dates.
What to Review Before Any Filing or Trip
Compare names, passport numbers, SEVIS IDs, program level, travel signature, and employment authorization. Ask the DSO about SEVIS questions; use CBP correction channels for admission-record errors; use consular processes for visa matters.
Your Action Checklist
Common Mistakes to Avoid
- Calling the visa stamp ‘my status.’
- Throwing away old I-20s.
- Assuming D/S permits unlimited stay despite a status violation.

Frequently Asked Questions
Can I stay in the U.S. with an expired F-1 visa?
Often yes if you were properly admitted for D/S and continue maintaining F-1 status; the expired visa normally matters when seeking reentry.
Can I work because my I-20 lists OPT?
The recommendation alone is not the EAD. For post-completion OPT, employment generally must wait for USCIS approval and the authorized EAD dates.
Which record shows D/S?
The I-94 admission record commonly shows F-1 and D/S.
