How Long Can You Stay in the U.S. on a B-1/B-2 Visa?

(UNITED STATES) A B-1/B-2 visa lets visitors enter the United States for business or tourism, but it does not set how long they can remain. That limit comes from the authorized stay shown on the I-94 form, and CBP officers usually allow up to 6 months per visit.

That distinction shapes every trip. It affects vacationers, family visitors, medical travelers, and people who come for short business meetings. It also matters because overstaying past the I-94 date can trigger bans, removal, and future visa denials.

The visa stamp is only the entry key

The B-1/B-2 visa in a passport is an entry document. It allows a traveler to ask for admission at a U.S. port of entry. It does not promise a six-month stay, and it does not create a right to remain until the visa expires.

CBP officers decide the stay after reviewing the trip purpose, return plans, finances, and ties to a home country. Those officers issue the admission record on the I-94 form, now available online through CBP’s I-94 system. That record controls the lawful stay.

Visa validity and authorized stay are different clocks. A visa can be valid for years, often up to 10 years with multiple entries. The stay can still be much shorter, including 1 month, a few weeks, or the standard 6 months.

What happens at the border

At entry, CBP often asks a few direct questions. Officers may ask where the traveler is staying, how long the visit will last, whether there is enough money for the trip, and whether the person has work or family ties abroad.

A strong answer set is simple and consistent. A tourist with a return ticket, hotel bookings, and a short itinerary usually presents a clean case. A visitor with vague plans, repeated long stays, or unclear funding draws more attention.

CBP then stamps the passport or records the admission electronically. The traveler should check the I-94 form right away and save or print it. The I-94 shows the class of admission, such as B-1, B-2, or B-1/B-2, and the exact date the stay ends.

Extensions inside the United States

When a trip needs more time, a visitor can request an extension by filing Form I-539, Application to Extend/Change Nonimmigrant Status. The form is available on the official USCIS page for Form I-539. This filing does not guarantee approval.

USCIS expects a real reason. Medical treatment, canceled travel, or another unexpected event can support the request. The applicant must also show enough money to stay without working and must prove an intention to leave after the extended visit.

The filing should go in at least 45 days before the I-94 expires. As described in current guidance, people who file on time can stay while the request is pending. A typical extension adds 6 more months, and the total stay for one trip usually reaches no more than 1 year.

Travelers with special rules

Canadian citizens follow a different path. Many enter the United States without a B-1/B-2 visa for land or sea travel, and CBP still controls the stay. The common limit remains 6 months, and unlawful presence can still build after that date.

Visa Waiver Program travelers have a tighter system. They can stay up to 90 days, but they cannot extend that stay or change status in the same way a B-1/B-2 visitor can. An overstay can block future use of the program and trigger long re-entry bars.

Short study visits also need care. Recreational classes under 18 hours per week fit the visitor category. Degree study does not. A traveler who wants to enroll full-time needs a student visa path instead.

Why overstays cause lasting harm

Missing the I-94 deadline creates unlawful presence. That can lead to detention, removal, and serious future travel problems.

The main bars are stark. A stay of 180 days or more can trigger a 3-year re-entry bar. A stay of 1 year or more can trigger a 10-year bar.

There are narrow exceptions for extraordinary events, including serious medical problems or other urgent disruptions. In some cases, a short period of satisfactory departure may avoid unlawful presence, but that relief depends on proper documentation and fast action.

Future visa applications also become harder after an overstay. Consular officers look closely at whether the traveler truly intended a temporary visit.

Recent policy pressure is changing the climate

Visa rules for visitors are facing tighter scrutiny in 2026. Analysis by VisaVerge.com notes that some nationalities now face shorter visa validity periods, and selected travelers from higher-overstay-risk countries may face bonds of $5,000 to $15,000 under the Visa Bond Pilot Program.

Interview requirements have also tightened. Renewals now require interviews if the previous visa expired more than 12 months ago. That change makes planning more important for frequent visitors, especially people who travel for family events, treatment, or recurring business meetings.

Filing early keeps the trip legal

Timing matters. A visitor should watch the I-94 date from the day of entry and set reminders well before it ends. If more time is needed, the extension request should go in early, with flight records, medical letters, financial proof, and a clear explanation.

A pending request is not a guarantee, but a timely filing helps preserve lawful stay while USCIS reviews the case. Filing late creates unnecessary risk.

For a visitor who enters for a wedding, a graduation, or a long medical appointment, the safest path is the same: respect the I-94 date, keep documents organized, and never assume the visa sticker controls the stay.

Real-world examples show how the rules work

A tourist arriving for a two-week trip may receive 6 months anyway. A visitor coming for treatment may receive the same period, then file Form I-539 if more time is needed. A family guest who plans to stay seven months must ask for an extension from inside the country before the I-94 expires.

A traveler who marries a U.S. citizen on a B-2 trip enters a different stage later, usually through immigrant filing forms after the wedding. The key issue remains intent at entry and compliance with the original stay.

The central rule stays simple: the B-1/B-2 visa opens the door, but the authorized stay on the I-94 form decides when the visit ends.
