ESTA, Visa, I-94, and Immigration Status Are Not the Same Thing
A plain-language guide to the difference between travel authorization, a visa, admission, the I-94 record, and immigration status in the United States.
Direct answer
What is the shortest way to understand the difference?
ESTA authorizes certain VWP travelers to seek travel to the United States. A visa is a travel document for a classification. Admission is CBP’s decision at the port of entry. The I-94 or admission record documents the class and authorized period. Immigration status is the legal position created or maintained under U.S. law.

ESTA is not a visa
CBP says this directly. ESTA supports travel under the Visa Waiver Program. It does not substitute for a visa when U.S. law requires one.
A visa does not guarantee admission
A visa generally allows a traveler to apply for admission in the classification shown. CBP still decides admission at the port of entry.
The I-94 or admission record matters more than the visa expiration date for the period of stay
A visa can remain valid after an individual stay ends. For VWP travelers, the admission is generally limited to 90 days.
Status can be lost even while a visa stamp is still valid
Status depends on compliance with the terms of admission and any approved extension, change, or other lawful basis.
Questions people actually ask
Frequently asked questions
If my ESTA is valid for two years, can I stay two years?
No. CBP states that VWP stays are generally limited to 90 days or less.
If my visa is valid, am I guaranteed entry?
No. A valid visa allows application for admission; CBP makes the admission decision.
Where should I check my authorized stay?
Use the admission record and official CBP information for the particular entry rather than assuming the visa expiration date controls the stay.
