Following arrival in the United States, visitors (i.e. nonimmigrant visa holders, those from visa-free countries) are issued a Form I-94 which determines allocated length of stay. The Form I-94 used to be a paper form attached to the visitor’s passport. Now it is saved electronically on the Customs and Border Protection (“CBP”) website. Unfortunately, many visitors overlook the Form I-94 which actually controls how long they can remain in the country.
The Form I-94 is the official record that proves a visitor entered the U.S. lawfully at a Port-of-Entry (“POE”). It also shows exactly how long the visitor is allowed to remain.
This guide explains what the Form I-94 is, why it matters, how to access it, and what to do if something is wrong.
Why is a Form I-94 Important?
The Form I-94 does more than confirm your entry into the United States. A visitor will need it for the following reasons:
It Proves Visitors Legal Status
The Form I-94 serves as evidence that a visitor arrived in the United States legally and was processed at a POE. Government agencies, employers, and schools often rely on this record to confirm the visitor’s immigration status.
It Controls the Length of Stay
The “Admit Until Date” on the Form I-94 determines how long a visitor may remain in the United States. While a visa allows a visitor to request entry at a POE, the Form I-94 controls how long the visitor may remain after entry.
It is Needed for Everyday Life
A visitor may need an Form I-94 to:
- Apply for a driver’s license;
- Request a Social Security number;
- Complete employment verification (Form I-9 or Employment Eligibility Verification);
- Apply to adjust immigration status;
- Enroll in school or confirm lawful presence.
A visitor arrives at the airport.
Electronic vs. Paper Form I-94
Nearly all Form I-94 records are issued electronically. The CBP automatically creates an arrival and departure record using electronic travel data, which eliminates the need for most paper forms.
Electronic Form Form I-94 (Most Travelers)
A visitor arriving at POE by air, sea, or land typically receives an electronic Form Form I-94. There is no form to complete during travel. Instead, CBP generates the record when the visitor is admitted at the POE.
If a visitor requires proof of lawful admission for work, school, or government purposes, the visitor must access and print the Form I-94 records by using the CBP Form I-94 website or the CBP Link mobile app.
Paper Form I-94 (Limited Situations)
A paper form Form I-94s is rare but may still be issued in limited circumstances, including:
- Certain refugee or asylee admissions;
- Specific parole or humanitarian entries;
- Situations where a paper copy is requested during inspection and issued in secondary processing.
If a visitor receives a paper Form I-94, it should be kept in their passports at all times. When departing the U.S., the visitor must surrender the paper form to the airline or CBP officer, depending on how long they were inside the country.
Departure Records
When a visitor departs the U.S, CBP records the departure electronically through carrier information.

Key Information on an Form I-94
TheForm I-94 contains several critical details. Review each item carefully after every entry.
- Form I-94 Admission Number: A unique 11-digit number assigned to the entry. Many immigration, employment, and government applications require this number.
- Class of Admission: The immigration status you entered under, such as:
This classification must match your purpose of staying in the United States
- “Admit Until” date (critical): The date that sets the deadline to leave the United States, extend your stay, or change status. Some foreign students on an F-1 or M-1 visa and exchange visitors on a J-1 visa use a D/S or Duration of Status, which allows them to remain in the U.S. as long as they comply with the terms of their approved program.
Common Form I-94 Problems and How to Fix Them
Form I-94 errors happen and ignoring them can carry real consequences. Acting quickly makes a difference. If an issue is not easy to resolve, speaking with a U.S. immigration attorney can help protect your status.
Incorrect Information
If the name, date, or class of admission is wrong, act quickly. Contact a CBP Deferred Inspection Site to request a correction.
Cannot Find Your Record
If the system cannot locate the Form I-94:
- Try different name formats (with or without middle name);
- Double-check passport numbers;
- Watch for letter-number mix-ups like O vs. 0 or I vs. 1.

Frequently Asked Questions About an Form I-94
Because the Form I-94 plays such a critical role in your immigration status, many visitors have questions about how it works in practice.
Do U.S. Citizens or Lawful Permanent Residents (“Green Card Holders”) need an Form I-94?
No. Form I-94 records apply only to nonimmigrants. U.S. citizens and Green Card Holders are not issued Form I-94s when entering the United States.
Is Form I-94 the same as a visa?
No. A visa allows you to request entry into the United States, but it does not control how long the visitor may stay. The Form I-94 sets the lawful period of stay after entry and determines when a visitor must leave or change status.
What if my paper Form I-94 is lost?
If a visitor loses a paper Form I-94, they can obtain a digital copy from the CPB website or apply for a replacement by filing Form I-102, Application for Replacement/Initial Nonimmigrant Arrival-Departure Document with the United States Citizenship and Immigration Services.
If a visitor is outside the U.S. or working with an immigration lawyer in the Philippines or Vietnam or elsewhere in Aisa that attorney can help guide you through the replacement process and make sure that your records remain accurate.
Should a visitor check their Form I-94 after every entry to the United States?
Yes. A visitor should review their Form I-94 every time there is an entry into the U.S., even if they have traveled many times before.
Errors in admission class or expiration of stay can occur at entry and may affect the visitor’s ability to work, study, or lawfully remain in the country. Catching a mistake early makes it much easier to correct.
Don’t Let an Form I-94 Mistake Put A Visitor’s Status at Risk
Since Form I-94 controls how long a visitor can legally remain in the United States, even a small mistake can create serious immigration problems.
With that in mind, reviewing records after every entry (and acting quickly if something looks wrong) can help protect the visitor in the future.
