FIFA PASS for the 2026 World Cup - how it works and what you actually need to enter the U.S.

How long can you stay in the U.S. on a tourist visa? The short answer is up to six months per visit, but that number isn't automatic, and it isn't guaranteed. A CBP (Customs and Border Protection) officer decides your actual permitted stay when you arrive at the port of entry, and many travelers get less than six months.
Here's the part that trips people up: your visa validity period and your allowed length of stay are completely separate things. A 10-year B1/B2 visa doesn't mean you can stay for 10 years, or even six months every time you enter. It means you can travel to a U.S. port of entry for up to 10 years. What happens once you get there is a different question entirely, and the answer lives on a document most travelers overlook.
Visa validity vs. length of stay on a B1/B2 tourist visa
This is the single most misunderstood part of the B2 visa length of stay rules. Your visa, the stamp in your passport, has a validity period that can range from a few months to 10 years. That period controls how long you can use the visa to travel to the United States. It says nothing about how long you can stay once you arrive.
Your permitted stay is determined separately by the CBP officer at the port of entry and recorded on your I-94, the electronic arrival/departure record. Think of it this way: the visa is your ticket to the door, but the CBP officer decides how long you're allowed inside.
For B1/B2 visitors, the maximum admission period is six months. But "maximum" doesn't mean "standard." Officers look at your stated purpose for visiting, your return ticket date, your travel history, and how much of your previous admission period you actually used. Someone visiting family for two weeks with a round-trip ticket will likely get six months on their I-94. Someone who stayed five months on their last visit and is back three weeks later may get far less, or face additional questions at the border.
How to check your I-94 and know your actual departure date
Your I-94 form is the definitive record of how long you can stay in the United States. Don't rely on the stamp in your passport because stamps can be unclear, smudged, or in some cases incorrect. The I-94 is what counts.
You can check your I-94 online at i94.cbp.dhs.gov by entering your name, date of birth, and passport number. The site shows your most recent admission date, your class of admission (B1, B2, or B1/B2), and your "admit until" date. That "admit until" date is your deadline to leave the country.
Check it every time you enter the U.S. Errors happen, and catching a mistake early is far easier than dealing with the consequences of an accidental overstay. If your I-94 shows a date that doesn't match what the officer told you, contact CBP to get it corrected before it becomes a problem.

Can you stay the full 6 months in the USA on a tourist visa?
Legally, yes, if your I-94 allows it. Practically, there's more to consider.
Staying the full six months once for a specific reason, like extended medical treatment, caring for a sick relative, or a long family visit, generally won't raise flags. The issue arises when it becomes a pattern. If you're consistently staying five or six months, leaving briefly, and then returning for another long stay, CBP officers will start asking questions. That pattern looks less like tourism and more like someone living in the United States without proper immigration status.
Future entries may result in shorter admission periods, more intense questioning at the port of entry, or even a denial of entry. There's no formal rule against staying the full six months, but immigration officers have wide discretion and they pay close attention to patterns. One long stay with a clear reason is very different from a repeating cycle of maximum stays.
What happens if you overstay your tourist visa?
Overstaying your I-94 expiration date, even by a single day, triggers serious consequences.
Your visa is automatically voided the moment you overstay. That means even if your 10-year B1/B2 visa still shows years of remaining validity, it's canceled. You'll need to apply for a new visa at a U.S. consulate before you can return, and the overstay will come up in that interview.
The consequences get worse the longer you stay past your departure date. Unlawful presence begins the day after your I-94 expires, and the clock matters:
| Unlawful presence | Consequence |
|---|---|
| 1 to 180 days | Visa voided, must apply for new visa, overstay on record |
| 180 days to 1 year | 3-year bar from entering the U.S. after departure |
| 1 year or more | 10-year bar from entering the U.S. after departure |
These bars apply once you leave the country. If you accumulate 180 days of unlawful presence and then depart, you can't return for three years. Over a year of unlawful presence triggers a 10-year bar. These aren't just visa denials; they're legal bars on admission that are very difficult to waive.
How to extend your tourist visa stay with Form I-539
If you need more time in the U.S. and your I-94 hasn't expired yet, you can file Form I-539 (Application to Extend/Change Nonimmigrant Status) with USCIS to request a B2 visa extension. The key word here is "before." You must file before your I-94 expires, not after.
A B2 visa extension can add up to six additional months to your authorized stay. The filing fee is $370 plus an $85 biometrics fee, for a total of $455. Processing times can stretch to several months, but the good news is that a timely filing generally protects your status while the request is pending. That means as long as you filed before your I-94 expired and haven't received a denial, you're not accumulating unlawful presence while you wait.
That said, extensions aren't a guaranteed approval. USCIS will look at why you need more time and whether the reason is consistent with tourist status. Filing multiple back-to-back extensions raises the same red flags as repeated long stays: it suggests you're trying to live in the U.S. on a visitor visa rather than actually visiting.
How long can you stay in the USA per year as a tourist?
There's no law that caps the total number of days you can spend in the U.S. per year on a B1/B2 visa. But the absence of a formal annual limit doesn't mean you can spend 11 months a year in the country.
CBP officers informally expect tourists to spend more time outside the U.S. than inside. Many immigration attorneys reference a practical guideline: spend roughly as much time outside the country as you spent inside before returning. This isn't a statute or regulation. It's a pattern-based standard that officers and adjudicators apply at their discretion.
If you spent four months in the U.S., waiting at least four months before your next visit is a reasonable approach. Someone who leaves for two weeks after a five-month stay and then tries to re-enter is likely to face tough questions or a shorter admission period. The goal is to demonstrate that you're genuinely visiting the United States, not using a tourist visa as a workaround for long-term residency.

When a tourist visa isn't enough: other options to consider
If you find yourself repeatedly stretching your B1/B2 stays to the limit or filing extensions, that's usually a sign that a tourist visa doesn't match what you're actually trying to do. The U.S. immigration system has visa categories designed for longer-term purposes, from work visas to green card pathways.
Tukki is a U.S. immigration provider that helps foreign nationals and their employers with work visas and green cards, from H-1B and O-1A to EB-1A and EB-2 NIW, with dedicated attorney support and full case visibility throughout the process. If your plans go beyond what a tourist visa allows, the right visa category can save you from the risks of overstaying or repeated entry denials.
