Form I-290B after a denial: motion to reopen, motion to reconsider, or appeal
9 mins read | Oct 16, 2026
How many days can you stay in the U.S. per year on a tourist visa? The honest answer is that there's no official annual limit. Unlike the Schengen Area's strict 90-out-of-180-day rule, U.S. immigration law doesn't set a maximum number of days per year for B1/B2 visitors.
But "no limit" doesn't mean "unlimited." Every time you arrive at a U.S. port of entry, a CBP (Customs and Border Protection) officer decides how long you can stay for that particular trip, up to a maximum of six months. And that officer can see your entire travel history. If your pattern looks like you're living in the U.S. rather than visiting, you can be questioned, admitted for a shorter period, or denied entry altogether.
So how do you know when you're pushing it? It comes down to what CBP actually looks at, how to calculate your time, a tax trap most visitors don't see coming, and what your options are if you genuinely need to spend more time in the country.
Is there an annual day limit for U.S. tourist visas?
No. There's no statute, regulation, or formal USCIS (U.S. Citizenship and Immigration Services) policy that caps the total days a B1/B2 visitor can spend in the U.S. per calendar year. Each admission is a standalone decision made by the CBP officer at the port of entry.
Under federal regulations, B-2 visitors are automatically granted up to six months at each entry. Technically, B1/B2 holders can be admitted for up to one year with extensions of six months, but in practice CBP grants the standard six-month period. Having spent extended time in the U.S. before isn't an automatic bar to a new B-2 admission, as long as there's a clear time limit on the visit and no intent to remain permanently. But here's the catch: a tourist visa can't be used as a way to create permanent residency by leaving and returning every six months. CBP generally takes the position that a person should stay no more than six months per year, even though no written policy requires that limitation. So if you enter and stay the full six months, you're likely to face problems when you try to re-enter after less than six months abroad. Scrutiny increases as you establish a pattern of frequent, extended stays.
This surprises a lot of people because other countries do set hard limits. In the Schengen Area, for example, visitors from visa-exempt countries can spend a maximum of 90 days within any rolling 180-day period, and the math is tracked automatically. The UK has similar guidelines for Standard Visitor visa holders. The U.S. system works differently: instead of a fixed formula, it relies on officer discretion at each entry.
That discretion is the key. A CBP officer won't just look at your current trip. They'll review your I-94 record, which logs every entry and exit, and evaluate whether your overall travel pattern is consistent with genuine tourism or short-term business visits.
What does CBP look at when you arrive?
The officer at the port of entry evaluates several factors before deciding whether to admit you. Your answers during the brief interview matter, but so does the data already in the system.
CBP considers the total time you've spent in the U.S. over the past 12 months, the ratio of time inside the country versus outside, your stated purpose for the trip, and whether you have a return ticket with verifiable plans to leave. They're looking for a pattern. Someone who spent five out of the last twelve months in the U.S. and is now arriving for another three-month stay looks very different from someone making a two-week vacation trip.
The core question the officer is asking themselves is simple: is this person visiting, or are they effectively living here? If the answer leans toward the latter, they have full authority to shorten your admission period, send you to secondary inspection for more questions, or turn you away entirely. CBP can deny entry for too many visits even if each individual trip was within the allowed time on your previous I-94.
The informal benchmarks immigration attorneys use
Since there's no official formula, immigration practitioners have developed rules of thumb over the years. These aren't law, and no CBP officer is required to follow them, but they reflect patterns that tend to avoid problems.
The most common guideline is straightforward: spend more time outside the U.S. than inside over any rolling 12-month window. Some attorneys frame this as the "180 day rule," suggesting that B1/B2 visitors shouldn't exceed roughly 180 days per year in the country. Others recommend matching your time out to your time in. If you stay for three months, leave for at least three months before returning.
| Guideline | What it means |
|---|---|
| More time out than in | Over any 12 months, days outside the U.S. should exceed days inside |
| ~180 days per year | A widely cited ceiling, though not legally binding |
| Match time out to time in | Stay 3 months, leave 3 months before returning |
| Consistent purpose | Each trip should have a clear, legitimate reason for visiting |
These benchmarks are useful, but they don't guarantee anything. A visitor who spends 170 days per year in the U.S. with long, uninterrupted stays will get more scrutiny than someone who makes four short trips totaling the same number of days. Context matters as much as the count.
How to calculate your time spent in the U.S.
If you're a frequent visitor, tracking your own days is one of the smartest things you can do. Here's how.
Step 1: Pull your I-94 records
Go to i94.cbp.dhs.gov and retrieve your travel history. The I-94 is your official arrival and departure record, and it shows every entry and exit the U.S. government has logged for you.
Step 2: Add up your days present
Count every day you were physically in the U.S. during the last 12 months. Include both the arrival and departure dates.
Step 3: Compare to your days outside
Subtract your days present from 365 to see how much time you spent outside the country. If the number inside is larger than the number outside, that's a warning sign.
Here's an example. Say you arrived January 1 and left April 1 (90 days). Then you returned July 1 and left September 1 (62 days). By September, you've spent 152 days in the U.S. out of roughly 243 days in the year. You're approaching the informal 180-day line, and CBP can see that ratio on their screen the next time you land.

Why "visa runs" don't work
A common strategy among frequent visitors is the visa run: fly to Mexico or Canada for a day or two, then re-enter the U.S. to "reset the clock." This doesn't work.
CBP officers see your full travel history, and a brief departure followed by an immediate return actually makes things worse. It reinforces the impression that you're living in the U.S. and using short border crossings to maintain the appearance of separate trips. Officers are specifically trained to spot this pattern, and it's one of the fastest ways to get a shorter admission period or an outright denial.
The time between U.S. visits matters. A two-day trip to Cancun between two three-month stays tells CBP exactly what you're doing. To demonstrate genuine nonimmigrant intent, you need meaningful time spent outside the U.S., with ties to your home country, like a job, a lease, family, or ongoing business obligations, that prove you actually live somewhere else.
What to do if you need to spend more time in the U.S.
If your situation genuinely requires more than about six months per year in the country, a B1/B2 tourist visa probably isn't the right fit. Pushing the limits of a tourist visa risks denied entry, potential bars on future travel, and the tax complications described above.
You have a few options worth exploring. If you're already in the U.S. and need more time on your current trip, you can apply for an extension of stay using Form I-539 before your authorized period expires. This doesn't guarantee approval, but it's the proper way to extend a single visit beyond the date on your I-94.
For longer-term needs, the better path is usually a different visa category altogether. Depending on your situation, that might be a work visa like the H-1B or O-1A, a business visa like the L-1 or E-2, or even a green card if you qualify. Each of these comes with its own requirements and timeline, but they're designed for people who need to be in the U.S. for extended periods.
