Tourist Visa USA Requirements: Visitor Visas, ESTA, Port of Entry Rules, and Extensions

To visit the United States temporarily for business or pleasure, you generally must get a nonimmigrant visitor visa first. You can travel without a visa only if you are a citizen of 1 of the 42 countries in the Visa Waiver Program, which U.S. Customs and Border Protection states allows stays of up to 90 days with an approved ESTA. When you arrive at a U.S. port of entry, U.S. Customs and Border Protection officers inspect every traveler and issue a Form I-94 Arrival-Departure Record that sets your authorized stay expiration date, and U.S. Citizenship and Immigration Services recommends filing Form I-539 at least 45 days before that date if you entered on a visitor visa and need to extend your stay or change status.

Do you need a tourist visa to visit the USA?

U.S. Citizenship and Immigration Services (USCIS) says that if you want to visit and not live in the United States, you must generally get a visitor visa before traveling. Nonimmigrant visas are issued to travelers who intend to remain in the United States for a temporary, less than permanent period. If you plan to travel to the United States for reasons other than business or pleasure, such as studying, working as a crew member, or working as a journalist, you cannot use a visitor visa and must apply for a visa in the appropriate category through the U.S. Department of State.

USCIS rules distinguish between business visitors (B-1 visa category) and pleasure or tourist visitors (B-2 nonimmigrant category), while travelers from certain countries are exempt from the visa requirement under the Visa Waiver Program (WT and WB classifications). When planning your trip, check which entry path and domestic status rules apply to your nationality and purpose of travel.

• Temporary visitor visa (B-1 or B-2): Required for most travelers visiting temporarily for business or pleasure who are not exempt.
• Visa Waiver Program (WT or WB): Permits citizens of 42 participating countries to travel for business or tourism for stays of up to 90 days without a visa after receiving authorization through the Electronic System for Travel Authorization (ESTA).
• Other nonimmigrant categories: Required if your purpose is study (such as academic F or vocational M students), temporary employment, crew service (D visa), or journalism (I visa).

Visa Waiver Program (VWP) and ESTA requirements

Administered by the Department of Homeland Security (DHS) in consultation with the State Department, the Visa Waiver Program (VWP) permits citizens of 42 countries to travel to the United States for business or tourism for stays of up to 90 days without a visa. In return, those 42 countries must permit U.S. citizens and nationals to travel to their countries for a similar length of time without a visa for business or tourism purposes.

Before traveling under the Visa Waiver Program, you must use the Electronic System for Travel Authorization (ESTA), an automated system that determines eligibility to travel to the United States under the VWP. The ESTA application collects biographic information and answers to VWP eligibility questions. CBP states that ESTA applications may be submitted at any time before travel, though it recommends applying as soon as you begin preparing travel plans or before buying airline tickets.

Receiving travel authorization via ESTA does not determine whether you are admissible to the United States. U.S. Customs and Border Protection officers determine admissibility upon your arrival at the port of entry. In addition, USCIS rules bar travelers admitted under the Visa Waiver Program (WT and WB classifications) from applying to extend their stay or change their nonimmigrant status on Form I-539 inside the United States.

Port of entry inspection and Form I-94 requirements

Almost a million individuals enter the United States daily, and CBP states that every person arriving at a U.S. port of entry is subject to inspection by CBP officers for compliance with immigration, customs, and agriculture regulations. During this process, CBP officers review your travel documents and purpose of visit before authorizing admission.

When CBP authorizes your admission at a designated port of entry, you receive a stamped Form I-94, Arrival-Departure Record. International travelers can use CBP's I-94 system to apply for a provisional I-94 before arrival, retrieve their I-94 or I-95 admission number and record as proof of legal visitor status, and pull a limited travel history of their U.S. arrivals and departures. The date in the lower right-hand corner of your Form I-94 determines the exact date your authorized stay expires.

CBP also maintains digital tools and trusted programs for international visitors. Pre-approved travelers can use risk-based Trusted Traveler Programs (Global Entry, TSA PreCheck, SENTRI, NEXUS, and FAST), while non-U.S. citizen travelers can use the Verify My Exit (VME) mobile application to biometrically record their departure from the United States. If you lose your Form I-94 while in the country, USCIS states you may apply for a replacement by filing Form I-102, Application for Replacement/Initial Nonimmigrant Arrival/Departure Record.

What the officer checks and our pre-travel preparation checklist

Whether you are speaking with a consular officer abroad for a B-1/B-2 visa or answering a CBP officer during your immigration, customs, and agriculture inspection at a U.S. port of entry, the government checks that your visit is temporary, that your activities match the business or pleasure rules of your category, and that you will depart before your authorized stay expires. Under USCIS rules, visitors cannot begin studying or working without prior authorization, and violating the conditions of your admission puts you out of status.

Use this preparation plan and checklist written by our team to organize your facts and records before you travel.

• State your temporary purpose clearly: Be ready to explain in one sentence that you are visiting for business or pleasure and not to live, study, or work without authorization in the United States.
• Have customs and agriculture facts ready: Because CBP conducts customs and agriculture inspections alongside immigration checks for every arriving traveler, know every food, agricultural item, or monetary instrument you are carrying.
• Keep your arrival record accessible: Know how to look up your electronic Form I-94 record and travel history on CBP's site after admission so you have proof of legal visitor status.

Requirements to extend your tourist stay in the U.S. (Form I-539)

If you are in the United States on a B-1 or B-2 visitor visa and want to stay beyond the date indicated on your Form I-94, USCIS guidance states that you may apply for an extension of stay by filing Form I-539, Application to Extend/Change Nonimmigrant Status, either online or by mail before your Form I-94 expires. Supplemental Information for Application to Extend/Change Nonimmigrant Status (Form I-539A) may also be filed, where applicable. USCIS recommends applying at least 45 days before your authorized stay expires.

To qualify to extend your stay, you must meet five USCIS eligibility requirements: you were lawfully admitted into the United States with a nonimmigrant visa, your nonimmigrant visa status remains valid, you have not committed any crimes that make you ineligible for a visa, you have not violated the conditions of your admission, and your passport is valid and will remain valid for the duration of your stay.

If your status expired before you filed Form I-539 with USCIS, or if you violated the terms of your status such as by working without authorization, you are out of status. If you remain in the United States longer than authorized, you may be barred from returning and/or removed (deported) from the United States. USCIS excuses a late Form I-539 filing only if you show when filing that the delay was due to extraordinary circumstances beyond your control, the length of the delay was reasonable, you have not otherwise violated your status, you are still a bona fide nonimmigrant, and you are not in removal proceedings.

• Eligible on Form I-539: B-1 and B-2 nonimmigrant visitors, F and M students applying for reinstatement, K-3/K-4 nonimmigrants, V nonimmigrants, and eligible dependents of E principal nonimmigrants.
• Ineligible to extend stay: Travelers admitted under the Visa Waiver Program (WT or WB), crew members (D visa), travelers in transit (C visa or TWOV), fiancé(e)s and dependents (K-1/K-2 visa), and informants on terrorism or organized crime (S visa).

Requirements to change your status while in the U.S. (tourist to student or worker)

If you arrived in the United States as a tourist and want to change the purpose of your visit, such as becoming a student, USCIS rules require you or your employer to file an application to change your nonimmigrant status before your authorized stay on Form I-94 expires. USCIS recommends applying as soon as you determine that you need to change to a different nonimmigrant category, and at least 45 days before your stay expires.

Until you receive approval from USCIS, do not assume the status has been approved, and do not change your activity in the United States. Specifically, if you are currently a nonimmigrant tourist, you must not begin attending school as a student until USCIS has authorized your change of status. Even if you are approved for another status in the future, USCIS requires you to file Form I-539 to bridge any gap that might arise between the expiration of your current status and the validity start date of your future status.

Certain visitor situations do not require a change of status application. If you were admitted to the United States for business reasons in the B-1 visa category and wish to remain in the United States for pleasure before your authorized stay expires, you do not need to apply to change your nonimmigrant status.

Worked example written by our team (invented applicant): Maria enters the United States on a B-2 tourist visa, and CBP issues her a Form I-94 with an authorized stay expiring on August 30. In June, she is admitted to a full-time university program starting September 15 and decides to change her status from B-2 tourist to F-1 academic student. Following USCIS rules, Maria checks that her passport is valid for the entire requested period of stay in the new student classification and files Form I-539 online on July 10, which is 51 days before her August 30 Form I-94 expiration date (meeting the 45-day USCIS recommendation). Because her B-2 status expires on August 30 before her September 15 program start, her timely Form I-539 filing also covers the required bridge of status, and she does not attend any classes until USCIS approves her F-1 status.

Form I-539 filing tips, edition dates, and rejection rules

When completing Form I-539 on paper to mail, make sure the form edition date (08/28/24, listed in mm/dd/yy format) and page numbers are visible at the bottom of all pages, and that all pages come from the same form edition. If any pages are missing or come from a different edition, USCIS may reject your form. Filing your request on the wrong form may also result in the rejection or denial of your case, and USCIS will not refund your filing fees if your case is denied.

USCIS will automatically reject your Form I-539 or Supplemental Form I-539A if you forget to sign the form or leave out any of the required rejection fields below.

• Form I-539 Part 1 (Information About You): Must include Family Name, Mailing Address, Date of Birth, and Current nonimmigrant status.
• Form I-539 Part 2 (Application Type): Must select what you are applying for (item 1., 2., or 3.a.), the status you are requesting (3.b or 3.c), and the Total number of People Included in This Application.
• Form I-539A Part 1 (Information About the Person filing Form I-539A): Must include Family Name.
• Signature requirement: Every Form I-539 and Form I-539A must be signed, or USCIS will reject the unsigned form.

Practice example

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

State your true reason for visiting in one plain sentence that fits business or pleasure, such as sightseeing, visiting relatives, or attending business meetings, and give your exact planned departure date. If you are traveling under the Visa Waiver Program with ESTA, confirm that your stay is 90 days or less and that you know VWP stays cannot be extended. If you are entering on a B-1 or B-2 visitor visa, make sure your planned return date falls within your requested stay and that your passport remains valid for the entire duration of your visit. Have your return ticket details, your U.S. lodging address, and proof that you will return to your residence abroad ready to show if the officer asks. If you plan to study or work instead of visiting for business or pleasure, do not seek entry as a tourist, because USCIS and CBP rules require you to hold the appropriate visa category before engaging in those activities.

Consular and CBP officers check that your activities match a temporary visitor classification (business or pleasure rather than unauthorized work or study) and that you intend to depart before your Form I-94 or 90-day VWP period expires.
