Thousands of people enter the United States every year with a tourist visa and believe that the expiration date of their visa determines how long they can stay in the country. However, U.S. authorities point out that the key document to know your authorized stay is the I-94 form, the electronic record generated by U.S. Customs and Border Protection (CBP) at the time of your admission.
Checking this record after each entry can help you detect errors, avoid immigration problems, and even prove that your stay in the United States is legal. According to CBP, the Department of State, and various specialized guides from ViveUSA, these are the most important details you should verify.
1. The date of admission
The I-94 shows the exact day you were admitted to the United States. This data is part of your immigration history and serves as official evidence of your legal entry into the country.

If the date is incorrect, it could lead to inconsistencies in future immigration procedures or visa renewals.
2. The category under which you entered
Another fundamental piece of data is the "Class of Admission." This indicates under what type of visa or permit you were admitted, whether as a tourist, student, business visitor, or another immigration category.
If you entered with a B1/B2 visa and another classification appears, it is advisable to request a correction as soon as possible.
3. The deadline for staying in the United States
This is probably the most important piece of data on the I-94. In the "Admit Until Date" section, the date until which you can legally remain in the United States appears. CBP and the Department of State remind you that this date, not the visa validity, is what determines your authorized stay.
Staying longer than permitted can lead to complications in future trips or immigration applications.
4. Your I-94 registration number
The system also assigns a unique admission number, known as the I-94 Number or Admission Record Number. This number may be requested in immigration procedures, applications with USCIS, or labor or academic processes.
For this reason, it is recommended to download or print a copy of your record.
5. Verify that your name and personal data are correct
CBP recommends carefully checking that your name, surnames, date of birth, and passport details match your official documentation exactly.
An apparently small error can cause difficulties when proving your immigration status or checking your travel history.
6. Your history of entries and exits
In addition to showing your most recent admission, the official I-94 portal allows you to check part of your travel history to the United States. There, you can verify the entry and exit dates registered by immigration authorities.
This tool is especially useful if you are preparing immigration paperwork or a future visa application.
7. Ensure your exit is recorded correctly
CBP warns that, in some cases, land exits to Mexico or Canada may not be correctly reflected in the system. Therefore, it is recommended to keep evidence of your departure, such as transport tickets, receipts, or immigration stamps, especially if you will not be returning to the United States before your authorized period expires.
Verifying this point can help you avoid having an overstay erroneously appear on your record.
How to check your I-94?
Travelers can access their immigration record for free through the official CBP I-94 portal. The system allows you to download the most recent record, check travel history, and verify how much authorized time remains. To log in, you generally need your passport number, date of birth, and the country that issued the document.
Why is it important to check it?
Immigration experts highlight that many travelers focus only on the visa expiration date and forget to check the I-94. However, the document is the official proof of admission and contains the information that authorities use to determine if a person respected the conditions of their stay.
Therefore, after each entry into the United States, it is worth taking a few minutes to review the I-94 and confirm that all information is correct.
