How long can you stay in the USA with a tourist visa?

Tourists entering the United States on a B-1 or B-2 visitor visa are normally admitted for a maximum of 6 months per visit, according to U.S. Citizenship and Immigration Services (USCIS). If you enter without a visa under the Visa Waiver Program (WT or WB status), your stay is limited to up to 90 days. Your visa sticker does not control how long you can stay. Instead, U.S. Customs and Border Protection (CBP) sets your exact departure date when you arrive and records it on your admission stamp and Form I-94 Arrival-Departure Record.

Maximum length of stay by visitor category

How long you can stay in the US with a tourist visa depends on the status U.S. Customs and Border Protection grants you at the port of entry. USCIS groups temporary business and pleasure visitors into the categories below, each with its own maximum admission period and extension rules.

Visa validity vs. how long you can actually stay

One of the most common mistakes visitors make is confusing the expiration date printed on the visa in their passport with how long they are allowed to remain in the United States. USCIS explains that a visa simply lets you travel to the US and apply to enter during the visa's validity period. Having a valid visa does not guarantee that you will be admitted, and it does not control the length of your stay.

Nonimmigrant visas are issued either for a single entry or for multiple entries. A multiple-entry visa lets you apply to enter the US repeatedly for as long as the visa remains valid. Each time you arrive, a CBP officer decides whether to admit you, grants your specific nonimmigrant classification (such as B-2 for tourism or B-1 for business), and sets the exact period you are authorized to stay.

Because the visa date and the admission period serve two different purposes, their dates rarely match. You can enter the US while your visa is valid and remain until the date on your Form I-94 or admission stamp, even if the visa sticker in your passport expires while you are inside the country.

How to check your exact departure deadline on Form I-94

When you enter the United States, CBP provides an admission stamp in your passport annotated with three pieces of information: your date of admission, your class of admission (such as B2 or WT), and your admitted-until date.

Since April 30, 2013, CBP has automated Form I-94 at air and sea ports of entry. Instead of stapling a paper card into your passport, CBP scans your travel document and generates an electronic arrival-departure record. CBP also issues Form I-94s electronically at land border ports of entry, though CBP may still provide a paper Form I-94 to certain classes of travelers, such as parolees and refugees, whenever CBP determines a paper form is appropriate.

Always check your exact expiration date right after you arrive rather than assuming you were given a full 6 months. Follow this checklist to verify your deadline:

• Look at the CBP admission stamp in your passport right at the port of entry to see the class of admission and the admitted-until date written by the officer.
• If you received a paper Form I-94, check the front side with your name. The lower right-hand corner shows your nonimmigrant status and the date your authorized stay expires.
• If you were issued an electronic Form I-94, look up and print your electronic Form I-94 on the CBP I-94 portal using your passport information.
• If USCIS approved an extension of stay or change of status after you arrived, check the new Form I-94 or Form I-797 Notice of Action from USCIS for your updated expiration date.
• If you find an error on an I-94 issued by CBP at entry, take your passport, visa, and I-94 record to the nearest CBP Port of Entry or CBP Deferred Inspection Office, or call CBP at 1-877-227-5511 between 8:30 AM and 5:00 PM Eastern Time, Monday through Friday.
• If you find an error on an I-94 issued by USCIS, file Form I-102 or schedule an appointment with a local USCIS office if the error was made by USCIS.

Special rules for Visa Waiver Program, Canadian, and Mexican visitors

Not every tourist enters with a traditional B-1/B-2 visa stamp in their passport. USCIS outlines specific stay rules for travelers who do not require a traditional visa:

Visa Waiver Program (WT and WB status). Citizens of participating countries who obtain Electronic System for Travel Authorization (ESTA) approval before boarding can visit for business (WB) or tourism (WT) for up to 90 days. Once approved, an ESTA is valid for two years or until your passport expires.

Canadian and Bermudian citizens. Citizens and nationals of Canada or Bermuda generally do not need a visa to enter as B-1 or B-2 visitors. A Canadian citizen admitted without being issued a Form I-94 is admitted in B-1 or B-2 status for an authorized stay of up to 6 months.

Mexican citizens. Mexican citizens can enter as B-1 or B-2 visitors with a visa or a Border Crossing Card (BCC), which is a B nonimmigrant visa issued in card format with an optical stripe on the back. A Mexican citizen who is admitted without being given a Form I-94 is granted B-1 or B-2 status for an authorized stay of up to 3 days and must remain within 25 miles of the land border, or within 75 miles of the land border in Arizona.

How to extend your tourist visa stay with Form I-539

If you were admitted in B-1 or B-2 status and want to stay longer than the date on your Form I-94, you can apply to USCIS for an extension of stay using Form I-539 (Application to Extend/Change Nonimmigrant Status). A husband, wife, and their unmarried children under 21 who hold the same status can file together on a single Form I-539 if everyone is asking for an extension to the same date.

USCIS recommends filing your extension application at least 45 days before your authorized stay expires, and USCIS must receive your application before the expiration date on your Form I-94 passes. Under USCIS rules (updated January 24, 2024), you may apply to extend your stay only if you meet all of these requirements:

• You were lawfully admitted into the United States with a nonimmigrant visa.
• Your nonimmigrant status remains valid and your Form I-94 expiration date has not yet passed.
• You have complied with all the terms and conditions of your status (such as not working or enrolling in school without authorization).
• You have not committed any crimes or acts that make you ineligible for a visa or immigration benefit.
• Your passport is valid and will remain valid for the entire duration of your requested stay.
• You intend to continue doing the same type of temporary visitor activities for which you were admitted, and you have definite plans to return to your residence abroad once your status ends.

Worked example: planning your 45-day extension window

Our team built this timeline example to show how the USCIS deadlines work in practice for a B-2 visitor.

Suppose you fly into the United States on March 1 and the CBP officer admits you in B-2 status until August 31. Your visa stamp in your passport happens to expire on July 15. Because your Form I-94 controls your authorized stay, the July 15 visa expiration date does not require you to leave in July. Your legal deadline to depart the US is August 31.

In June, you decide you want to extend your visit. Counting back 45 days from your August 31 Form I-94 expiration date puts your recommended target filing date on July 17. If you submit Form I-539 on July 17, USCIS receives it well before August 31. If you instead wait until September 2 to file, your I-94 has already expired, and USCIS states it usually will not grant an extension unless you prove compelling, unforeseen circumstances beyond your control prevented a timely filing.

What happens while your Form I-539 extension is pending?

Many visitors worry about what happens if they file Form I-539 on time, before their Form I-94 expires, but USCIS does not finish deciding the case before the original I-94 date passes. USCIS Nonimmigrant Services explains the exact legal rules for this period:

While your timely filed application is pending after your I-94 date passes, your lawful nonimmigrant status technically ends and you are out of status. However, as a matter of discretion, the Department of Homeland Security (DHS) generally defers bringing removal proceedings until USCIS decides your extension request. Most importantly, you do not accrue unlawful presence under section 212(a)(9)(B) of the Immigration and Nationality Act while a timely filed extension application is pending.

What happens next depends on how your case concludes:

• If USCIS approves your extension: the approval relates back to the date your original admission stamp or Form I-94 expired. Your entire time waiting while the application was pending is then considered to have been in lawful status.
• If USCIS denies your extension after your I-94 expired: you must depart the United States immediately. In addition, any nonimmigrant visa in your passport granted in connection with that classification automatically becomes void. Once your visa is voided, you must submit any future visa application at a US consulate in your home country rather than a third country, except in rare instances determined by the Department of State.
• If you leave the US before USCIS makes a decision: keep a complete copy of your Form I-539 application plus the USCIS receipt notice. Bring both documents to show the immigration inspector the next time you travel to the US. Without that receipt notice, you may be denied entry for appearing to have overstayed on your previous visit.

Why Visa Waiver (ESTA) visitors cannot extend, and the emergency exception

If you entered the United States under the Visa Waiver Program (WT or WB status), you are not eligible to file Form I-539 to extend your stay or to change to another nonimmigrant status. You must leave within your initial 90-day admission period. Other categories barred from extending stay include crewmembers (D), transit travelers (C and TWOV), informants (S), and K-1/K-2 fiancé(e) visa holders.

USCIS provides only one narrow exception for Visa Waiver Program visitors: satisfactory departure. If a serious emergency prevents you from departing within your 90-day period, you may request that USCIS grant a period of satisfactory departure of up to 30 days. USCIS states that satisfactory departure is granted only in limited cases for serious emergencies, such as hospitalization, or weather or worker strikes that delay or cancel flights for more than 24 hours.

To request satisfactory departure, you must schedule an appointment with the local USCIS office that has jurisdiction over the place where you are staying and present evidence of the emergency. If granted, and if you leave within the allotted window (up to 30 days), you are treated as having satisfactorily completed your visit without overstaying.

Consequences of overstaying and rules you must follow during your stay

Remaining in the United States past the date on your Form I-94 carries severe immigration consequences. USCIS warns that if you stay longer than authorized, you may be removed (deported) from the United States and barred from returning.

Specifically, if you remain in the US for more than 180 days without lawful presence (meaning you stayed past your authorized period or violated the terms of your status) and then leave, you are barred from getting a visa, returning to the US, or obtaining status until you remain outside the United States for a specific statutory period. In some instances, violations can permanently bar your return, even if you still hold an unexpired visa sticker in your passport.

To protect your status while you are in the United States, you must also follow the activity rules for B-1, B-2, WT, and WB visitors:

• No employment: working in the US is not authorized for B-1, B-2, WT, or WB visitors. A B-1 business visitor may conduct narrow business activities such as attending meetings on behalf of a foreign employer, but cannot work for or receive pay from a US employer, and any salary while in the US must come directly from the foreign employer abroad.
• No academic study: you generally cannot attend school on a visitor visa. You may take a short recreational seminar as a supplemental part of your trip, not the primary reason, and you cannot extend your stay to continue such a program. If you want to visit the US to look for a school before enrolling, you must tell the consular officer and receive a B-2 visa with a prospective student notation, then get a Form I-539 change of status approved before starting classes.
• Switching between tourism and business meetings: if you entered as a B-1 visitor and want to sightsee after your meetings finish, or entered as a B-2 tourist and need to attend a business meeting, USCIS states you do not need to apply to change between B-1 and B-2 as long as you leave before your authorized stay expires.
• Turning in a paper Form I-94 on departure: if you arrived by air or sea, CBP records your exit electronically through the airline or ship carrier. If you received a paper Form I-94 and forgot to turn it in when you left by land, USCIS instructs you to mail the form to DHS, CBP SBU, 1084 South Laurel Road, London, KY 40744, USA so your timely departure is recorded.

Practice example

How long do you plan to stay in the United States, and why did you stay for five months on your last visit?

State the exact number of weeks or days for your current trip and give your planned arrival and return dates so they match your DS-160 and flight itinerary. Avoid saying you want to stay for six months simply because six months is the normal maximum admission period. Instead, tie your trip length to a specific, time-bound purpose, such as a two-week vacation or a family wedding, and name the exact date you need to be back at your job or home abroad. For the second part of the question, explain the specific reason your previous visit lasted five months and confirm the exact date you departed before your Form I-94 expired. If you applied for an extension on Form I-539 during that earlier trip, have a copy of your Form I-539 application, your USCIS receipt notice, or your Form I-797 approval notice ready in your folder to show that you complied with all the terms of your status and left on time.

Consular and border officers check whether you have definite plans to return to a residence abroad and whether you complied with the terms of your status on previous visits. Giving exact dates and carrying your prior Form I-94 record or USCIS receipt notice proves you did not overstay or use a visitor visa to live or work in the United States.
