B-2 visa rules: what you can and cannot do, how long you can stay, and how to extend

The B-2 visitor visa lets you enter the United States temporarily for tourism, vacation, medical treatment, or visiting family and friends. You cannot work, study for credit, give paid performances, or live in the country permanently. Your legal length of stay is set by the expiration date on your electronic Form I-94 from U.S. Customs and Border Protection (often a six-month computer-generated period), not the expiration date printed on your visa sticker. If you need more time, U.S. Citizenship and Immigration Services recommends filing Form I-539 at least 45 days before the Admit Until Date on your Form I-94 expires.

What is a B-2 visitor visa, and how does it compare to B-1 and ESTA?

Under U.S. federal law, foreign citizens who want to visit the United States must apply on their own for a visa unless they qualify to travel without one. Visitor visas are nonimmigrant visas for people entering the United States temporarily for business (category B-1), for tourism and pleasure (category B-2), or for a combination of both (B-1/B-2).

Because every visitor must apply on their own, there is no dependent or derivative B-2 visa. Spouses, children, and parents traveling together each submit their own application and qualify on their own.

The Visa Waiver Program, administered by the Department of Homeland Security in consultation with the State Department, allows citizens of 42 participating countries to travel to the United States for business or tourism for stays of up to 90 days without a visa through an approved Electronic System for Travel Authorization (ESTA). However, travelers admitted under the Visa Waiver Program cannot apply to extend their stay or change their nonimmigrant status inside the United States (except in narrow T or U nonimmigrant situations).

The table below compares how CBP and USCIS rules treat B-2, B-1, and Visa Waiver Program admissions.

Allowed activities on a B-2 visitor visa

U.S. Customs and Border Protection defines the B-2 category as a temporary visitor visa for tourism and pleasure. When you speak with a consular officer at your interview or a CBP officer at the port of entry, your planned activities must fit within the permitted B-2 list.

According to CBP guidance (Article-1024), activities permitted on a B-2 tourism visa include:

• Tourism and vacation (holiday) travel across the United States
• Visiting friends or relatives
• Receiving medical treatment in the United States
• Participating in social events hosted by fraternal, social, or service organizations
• Participating as an amateur in musical, sports, or similar events or contests, provided you are not paid for participating
• Enrolling in a short recreational course of study that is not for credit toward a degree, such as a two-day cooking class while on vacation

Prohibited activities on a B-2 visitor visa

Certain activities require a different visa category and are strictly barred while you hold visitor status. Engaging in a prohibited activity violates the terms of your status, puts you out of status, and can lead to removal (deportation) or bars from returning to the United States.

CBP lists six activities that cannot be done on a visitor visa:

• Study in an academic or degree-credit program (formal study requires a student visa such as an F-1 or M-1)
• Employment of any kind in the United States
• Paid performances, or any professional performance before a paying audience
• Arriving as a crewmember on a ship or aircraft (which requires a D crewmember visa)
• Working as foreign press, or in radio, film, print journalism, or other information media (which requires an I media visa)
• Establishing permanent residence in the United States, or using a visitor visa to live in the country as a de facto resident

How long can you stay? Form I-94 rules vs. your visa sticker

A common mistake B-2 visitors make is confusing the visa expiration date in their passport with their authorized length of stay. A visa only allows you to travel to a U.S. port of entry and request permission to enter. U.S. Customs and Border Protection officers determine your admissibility when you arrive and set the exact date your stay expires on your Form I-94, Arrival/Departure Record.

As CBP explains in its travel guidance, a six-month period of stay is computer-generated starting on the day you arrive on a B-2 admission, though the expiration date on your Form I-94 always controls. You can find your authorized status and the date your status expires in the lower right-hand corner of your Form I-94.

How Form I-94 works when you arrive and depart (per CBP Form I-94 guidance):

• Electronic records by default: Foreign visitors arriving by air, sea, or land no longer fill out a paper Form I-94 stub. CBP gathers arrival and departure records automatically and issues Form I-94 electronically.
• How to check and print your date: You can view and print your record from the CBP I-94 website using the Get Most Recent I-94 option or through the CBP Link mobile app. If you ask for a paper Form I-94 during inspection, CBP accommodates that request in secondary inspection.
• Alphanumeric I-94 numbers: Since May 2019, Form I-94 numbers are 11 characters long, following a format of 9 digits, followed by a letter in the 10th position, and a digit in the 11th position.
• Leaving by air or sea: When you leave the United States by commercial air or sea carrier, CBP records your departure electronically through manifest data from the carrier.
• Leaving by land to Canada or Mexico: If you received an electronic Form I-94 and depart via a land border without re-entering the United States before the expiration date stamped in your passport, your departure might not be recorded accurately. CBP advises non-residents of Canada or Mexico in this situation to keep evidence of their departure, such as an entry stamp requested from the Canada Border Services Agency (CBSA) or Mexico's Instituto Nacional de Migracion (INM), transportation tickets, pay stubs, or dated receipts. If you were issued a paper Form I-94, surrender it to the commercial carrier, CBSA, or CBP when you leave.

What happens if you overstay or violate B-2 rules?

Both USCIS and CBP warn that staying past the Admit Until Date on your Form I-94 carries severe immigration consequences. According to USCIS, if your status expired before you filed Form I-539 to extend or change your status, or if you violated the terms of your status such as by working without authorization, you are out of status.

Here is what USCIS states happens when you fail to maintain your nonimmigrant status or remain longer than authorized:

• You may be barred from returning to the United States in the future.
• You may be removed (deported) from the United States.
• Staying longer than the period granted at admission negatively affects your ability to obtain other immigration benefits or return to the United States later.
• Once you fall out of status, USCIS cannot change or extend your status except in very limited circumstances beyond your control. USCIS recommends that if you fall out of status, you leave the United States to limit the possible impact on your ability to come back in the future.

Rules for traveling to Canada, Mexico, or other countries during your visit

Many visitors want to take a side trip to Canada, Mexico, or another country during their U.S. vacation. CBP has a specific rule for contiguous territory (Canada and Mexico) and a different rule for countries further away (CBP Article-1422).

Visiting Canada or Mexico for up to 30 days: During your U.S. visit, you may travel to Canada or Mexico for up to 30 days and re-enter the United States under the original Form I-94 timeframe you received when you first arrived. Taking a short trip across the border does not reset or pause your six-month clock.

Worked timeline example from CBP rules: Suppose you arrive in the United States on July 10 with a B-2 visitor visa, and CBP grants a six-month stay on your Form I-94 through January 10. On December 10, you travel to Canada or Mexico for a two-week holiday and return to the United States. Your original six-month period is still up on January 10, and you must leave by January 10 to avoid an overstay (unless you timely applied for an extension of stay). By our calculation from USCIS's recommended 45-day Form I-539 filing window, if you wanted to apply to extend that July 10 to January 10 stay rather than leave on January 10, you would aim to submit Form I-539 by November 26 (45 days before January 10). CBP also recommends that you do not wait to leave until the very last day of your six-month stay because unexpected emergencies can happen.

Visiting non-contiguous countries (such as England or Costa Rica): If you leave the United States to visit a country other than Canada or Mexico and then come back to the United States, your return is treated as a brand-new admission rather than a continuation of your initial visit. CBP notes that the admission inspection on your return may be more strenuous. The inspecting CBP officer will look for evidence that you intend to go back to your country of citizenship to live rather than returning again and again to the United States after short trips abroad. If the CBP officer suspects you are trying to be a de facto resident of the United States, you will be refused entry. You can also be refused re-entry if you have been arrested or committed an illegal act resulting in a warrant since your visa was issued.

How to extend your B-2 stay with Form I-539

If your plans change and you want to stay in the United States longer than your initial admission, you must file Form I-539, Application to Extend/Change Nonimmigrant Status, with USCIS before your current authorized stay expires. While the form is required before your Form I-94 expiration date, USCIS recommends filing at least 45 days before your authorized stay expires.

Under USCIS guidance (Form I-539 instructions and Extend Your Stay rules), you are eligible to apply for a B-2 extension of stay only if you meet all of these requirements:

• You were lawfully admitted into the United States with a nonimmigrant visa.
• Your nonimmigrant visa status remains valid at the time of filing.
• You have not committed any crimes or acts that make you ineligible for a visa or immigration benefit.
• You have not violated the conditions of your admission (for example, by working or studying without authorization).
• Your passport is valid now and will remain valid for your entire requested period of stay in the United States.

Filing Form I-539 online vs. by mail, required fields, and late filings

USCIS allows B-2 visitors to submit Form I-539 either online or on paper by mail, depending on whether you are applying alone or with family members (USCIS Form I-539 Online Eligibility page). Check the USCIS Fee Schedule (Form G-1055) on the USCIS site before submitting, as USCIS does not refund filing fees if your case is denied or if you file on the wrong form.

Use this checklist from USCIS Form I-539 instructions to make sure your extension application is not rejected at intake:

• Choose online or paper filing correctly: You can file Form I-539 online if you are applying only for yourself without co-applicants (or if an attorney or accredited representative is filing for a single client). If you are applying as a family, you can either file together on a paper Form I-539 (using Form I-539A for each co-applicant) and pay a single fee, or apply online as separate individuals and pay a fee for each application.
• Use the accepted form edition for paper mailings: Under a September 14, 2026 court order in Presidents' Alliance on Higher Education and Immigration v. DHS, USCIS continues to accept the 08/28/24 edition of Form I-539 and is not accepting the 09/15/26 edition. Make sure the 08/28/24 edition date and page numbers are visible at the bottom of every printed page.
• Never leave mandatory rejection fields blank: USCIS states it will reject Form I-539 if you leave out Part 1 fields (Family Name, Mailing Address, Date of Birth, Current nonimmigrant status) or Part 2 fields (Application Type 1, 2, or 3.a, Status requested 3.b or 3.c, Total number of people included). On Form I-539A, leaving Family Name blank in Part 1 also causes rejection.
• Sign the form: USCIS rejects any unsigned paper Form I-539 or Form I-539A.
• Late filings are excused only in narrow cases: If you file after your Form I-94 expires, USCIS will excuse the delay only if it was due to extraordinary circumstances beyond your control. You must show the delay was reasonable, you have not otherwise violated your status, and you are still a bona fide nonimmigrant. You must also not be in removal proceedings.

Rules for changing from B-2 to student or another nonimmigrant status

If you entered the United States as a B-2 tourist and decide you want to change the purpose of your visit, such as becoming a full-time F-1 academic student or M-1 vocational student, you must apply to change your nonimmigrant status with USCIS before your authorized stay expires.

USCIS enforces three strict rules for B-2 visitors seeking a change of status:

• Do not start school or your new activity early: USCIS states clearly that until you receive approval from USCIS, you must not assume the status has been approved and must not change your activity in the United States. If you are a B-2 tourist, you cannot begin attending school as a student until USCIS has approved your change of status.
• Bridge any gap in status: Even if you are approved for another status starting in the future, USCIS requires you to file Form I-539 to bridge any gap between the expiration of your current B-2 status and the start date of your future status.
• Use the right form for employment categories: While Form I-539 is used to change status to F-1, M-1, J-1, or dependent categories (such as H-4, L-2, or F-2), you must not use Form I-539 to request a change of status to principal employment categories such as H-1B, H-2A, H-2B, H-3, L-1, O-1, P, Q-1, R-1, TN, or principal E treaty classifications. Those require an employer to file Form I-129, Petition for a Nonimmigrant Worker.

Practice example

What is the purpose of your trip to the United States, and how long do you plan to stay?

State the exact B-2 purpose of your visit in one plain sentence, such as visiting a relative, taking a vacation, or receiving medical care, along with your arrival and departure dates. Make sure the activity you describe is clearly permitted under B-2 rules and does not sound like unauthorized employment, child care that replaces a paid worker, or academic study. Name the city where you will stay, who is paying for the trip, and the specific date you will return home. If you are planning a longer visit within the standard six-month B-2 admission period, connect your timeline to a concrete event and state the exact job, business, family, or property commitment that requires you back in your home country on time. Have your passport, return travel plans, and proof of your ties and funds ready in case the officer asks to see them.

Consular and CBP officers use this opening question to verify that your planned activities fit B-2 tourism rules and that you intend to depart before your Form I-94 period expires rather than work or live in the United States as a de facto resident.
