I-94 Admission Record: What Controls Your Stay

Your visa expired last month. You are still in the United States. Are you in trouble?

For most people the honest answer is: probably not — and the fact that this surprises you is exactly why this page exists. The visa in your passport and your right to be in the United States are two different things, governed by two different documents, issued by two different agencies. Confusing them is one of the most common mistakes we see in nearly thirty years of practice, and it runs in both directions. Some people panic over an expired visa when nothing is wrong. Others relax because their visa is still valid — while they quietly slide out of status and into unlawful presence.

This page explains what your visa actually does, what your I-94 admission record actually does, and the third thing — your own conduct — that most websites leave out.

What a Visa Actually Does — and the Moment Its Job Ends

A visa does not admit you to the United States. It does something narrower: it permits you to travel to a U.S. port of entry and apply for admission. The State Department’s own regulation says it plainly:

“The period of validity of a nonimmigrant visa is the period during which the alien may use it in making application for admission. The period of visa validity has no relation to the period of time the immigration authorities at a port of entry may authorize the alien to stay in the United States.”

— 22 CFR § 41.112(a).

Read that second sentence again. The government that issues the visa (the State Department, through its consulates abroad) is telling you that the visa’s dates have no relation to how long you may stay. The decision to admit you — and for how long — belongs to a different agency entirely: Customs and Border Protection (CBP), at the port of entry. This is also why a valid visa is not a guarantee of entry. CBP can refuse admission to a traveler holding a perfectly valid visa, as we explain on our entry into the United States page.

The moment the CBP officer admits you, the visa’s job is finished. It has done the one thing it exists to do. Whether it expires the next day or in nine years, it says nothing about your status inside the country.

The I-94: The Record That Governs Your Stay

When CBP admits you, it creates an I-94 admission record. In the old days this was a white card stapled into your passport; today the record is electronic, and you retrieve it yourself from the CBP I-94 website after you leave the airport or land border crossing.

The I-94 states your classification (B-2, H-1B, F-1, and so on) and your “admit until” date. That date — not anything in your passport — is the outer limit of your authorized stay. Overstay it and you begin accruing unlawful presence, which can trigger the three- and ten-year bars to returning under INA § 212(a)(9). Our article on unlawful presence covers what those bars cost you.

Check It Every Time You Enter

Retrieve and check your I-94 after every single entry. CBP officers make data-entry mistakes, and an I-94 showing the wrong classification or the wrong date is your problem to fix, not theirs to catch. If you cannot pull up your record at all, or it shows something wrong, the fix is a visit to a CBP deferred inspection site — you cannot simply return to the airport and find the officer who admitted you.

What You Will Use the I-94 For

The I-94 is the document your life in the United States actually runs on:

• The Social Security office uses it to verify your status before issuing a Social Security number.
• The driver’s licensing agency uses it to set your license validity where you are work-authorized.
• USCIS wants it as proof of lawful admission for nearly any later benefit — a change of status, an extension on Form I-539, or adjustment of status to permanent residence.

Nobody at any of those counters will ask when your visa expires. They will all ask what your I-94 says.

When the Visa and the I-94 Disagree: A Worked Example

Here is where the two-document system produces results that look like errors but are not.

The length of your visa’s validity comes from your country’s “reciprocity schedule” — a country-by-country table the State Department maintains, reflecting how each country treats U.S. travelers. The length of your I-94 comes from something else entirely: the rules of your classification, and for petition-based workers, the approved petition.

Take an H-1B worker from Mexico. As of August 29, 2026, the State Department reciprocity schedule for Mexico issues an H-1B visa valid for 12 months with no reciprocity fee, or 36 months if the worker pays a $237 fee — and never longer than the approved petition. The H-1B petition itself is typically approved for three years.

So a Mexican engineer who skips the fee holds a visa that expires after one year — and an I-94 authorizing a three-year stay. After year one she is perfectly legal inside the United States on an expired visa. Her Australian colleague in the same office may hold a five-year E-3 visa with a shorter I-94. Neither document is wrong. They are answering different questions.

The Third Layer: Your Conduct

If this page stopped here, it would teach you the same half-truth most immigration blogs teach: “forget the visa, the I-94 is what matters.” That rule is incomplete in a way that hurts people.

The I-94 date is a ceiling, not a guarantee. You can fall out of status while your I-94 is still unexpired. The H-1B worker whose employment ends has lost the basis of her status even with two years left on the I-94. The F-1 student who drops below a full course load is out of status the day it happens. The B-2 visitor who takes a job is out of status regardless of any date. The I-94 sets the outer limit of the authorized period; your conduct determines whether you are actually maintaining status inside that window.

So the complete picture has three layers:

A note for F-1 students: the “D/S” (duration of status) notation that used to appear instead of a date is ending. Under a DHS final rule published July 17, 2026 and effective September 15, 2026, F students are admitted for a fixed period — up to the length of the program on the Form I-20, not to exceed four years, plus 30 days (Federal Register, July 17, 2026). Our article on the end of duration of status for F-1 students covers what that changes.

If your I-94 is running out and you have a reason to stay, act before it expires — file for an extension or change of status. Filing late is sometimes excusable, but as our article on untimely extensions and changes of status explains, you should never plan on the exception.

“My Visa Expired — So What?”

Now the question that opened this page. Your visa expired; you are still here; your I-94 is unexpired and you are maintaining status. Are you in trouble? No. An expired visa, by itself, has no effect on a lawful stay in progress.

The expired visa matters at exactly two moments:

When you leave and want to come back. Admission requires a valid visa, so ordinarily you would need to visit a U.S. consulate abroad for a new one before returning. The important exception: for short trips of 30 days or less to Canada or Mexico, automatic revalidation can treat your expired visa as extended for your return — one of the most useful and least-known rules in nonimmigrant travel. It has strict conditions, including that you must not apply for a new visa while abroad.

When the government takes it back. Revocation is not expiry. The State Department can revoke a visa — after a DUI arrest, for example — and a revoked visa can end your ability to return even though the printed date looks fine. If you receive a revocation notice, get advice before traveling.

The Six-Month Question: A Floor, Not an Allowance

Visitors — especially our Canadian neighbors — tend to believe in a “six-month rule”: you get six months per visit, or six months per year, and staying 179 days keeps you safe. The truth is more interesting, and knowing it protects you better than the folk version does.

The six months is real — as a floor on what the officer grants. The regulation, titled “Minimum six month admissions,” provides that an admissible B-2 visitor “will be admitted for a minimum period of six months, regardless of whether less time is requested” (8 CFR § 214.2(b)(2)). Exceptions require case-by-case approval for good cause. So the officer who hands a two-week wedding guest six months is following the rule, not being generous. The same regulation caps any single B-1/B-2 admission at one year, with extensions in increments of up to six months (8 CFR § 214.2(b)(1)).

What is not written anywhere is a rule that you may spend 180 days per year in the United States. No regulation says it. What the law actually says is harder-edged: under INA § 214(b), every visa applicant “shall be presumed to be an immigrant” until he satisfies the officer — at the consulate and again “at the time of application for admission” — that he is entitled to nonimmigrant status. Every admission is a fresh test. Prior admissions earn you no credit.

What we see at the border. What follows is practitioner observation from nearly three decades of client border reports, not a citable rule. Officers watching a returning visitor’s history focus on cumulative time, because cumulative days are the most visible thing on their screen. A traveler who spends more time in the United States than out of it looks like a resident, and the officer starts asking § 214(b) questions: Where do you live? Where do you work? Where do you pay taxes? The rolling “180 days in 365” that travelers whisper about is not a rule officers apply; it is roughly the point where the days themselves start answering those questions badly.

That distinction matters for how you plan. Taught as a number, travelers aim for 179 days and believe they are safe — and five consecutive years at 179 days presents a worse profile than one year at 200. Taught as evidence of intent, you understand what the officer is actually deciding and can prepare the right proof: a home, a job, family, tax residence — a life somewhere else. One example we see every winter: the visitor who leaves December 31 and returns January 3, believing the calendar reset the clock. Nothing reset. There is no calendar-year allowance to reset; there is only the continuous question of whether you still live somewhere else, and a three-day round trip is evidence about that question, not an answer to it.

For how B-2 admissions and extensions work in detail, see our B-2 visitor visa practical guide.

Two Governments Are Counting Your Days — Differently

Here is the trap waiting specifically for the long-stay visitor who has mastered everything above: while CBP is weighing your days as evidence of intent, the IRS is counting them under an entirely different formula — and lawful immigration status is no defense to it.

Under the substantial presence test, you become a U.S. resident for tax purposes if you are present at least 31 days in the current year and your weighted three-year total reaches 183 days — counting all of this year’s days, one-third of last year’s, and one-sixth of the year before. A snowbird spending roughly 180 days here every year sails past that threshold, entirely lawful in B-2 status and simultaneously a U.S. tax resident on worldwide income unless an exception applies. A “closer connection” exception and treaty tie-breakers exist, and Canadian commuters have special day-counting rules — but these require affirmative filings, not good intentions.

We are immigration lawyers, not tax lawyers, and this section is a warning light, not tax advice. If you are spending substantial time in the United States each year, put a cross-border tax advisor on your team. Canadians planning around these limits should also see our guide to Canadian immigration pathways.

Lost I-94, Wrong I-94, No I-94

Sometimes the electronic system has no record for a traveler who was plainly admitted — stamp in the passport, no I-94 online. When that happens, the fix is a CBP deferred inspection site, where an officer can correct the record. Do this promptly; it is far easier to fix while the entry is recent.

The harder version of the problem arrives years later. A person was lawfully admitted long ago, overstayed, and has lost both the passport and any record of the entry. Then life changes — a marriage to a U.S. citizen, for example — and lawful admission becomes the fact on which a whole green card case turns. In our practice we solve this with a Freedom of Information Act request to CBP for the client’s records of admission. CBP’s response gives us the entry data, we use it to retrieve the electronic I-94, and the client has recovered the proof of lawful admission the case needs. It is slow, it works, and it is much easier than trying to reconstruct an entry with affidavits.

When Ignoring the I-94 Goes Very Wrong

One last reason to take the date seriously. A person who overstays and comes to the government’s attention can be placed in removal proceedings — and people who have moved without updating their address, or who assume the problem will age away, sometimes get ordered removed at hearings they never knew about. Unwinding an in absentia removal order is possible in some cases, but it is a far harder fight than an extension filed on time would have been. If you have overstayed and received any notice from immigration authorities, or you fear a hearing happened without you, see our removal defense overview and get counsel promptly.

The Habit That Prevents All of This

Everything on this page reduces to one habit and one question. The habit: retrieve your I-94 from the CBP website after every entry, check the classification and the date, and calendar the date. The question, asked well before that date arrives: what is my plan — extend, change status, or leave?

If the answer is unclear — the I-94 is wrong, the date is close, the visa is expired and travel is coming, or the border officer’s questions are getting pointed — those are all solvable problems, and all of them are easier the earlier you bring them to us.
