Who needs a visa and who doesn't
Whether you need a visa depends on your citizenship and how long you plan to stay. Citizens of about 40 countries can enter the United States without a visa for tourism or business visits up to 90 days — this is called the Visa Waiver Program. Citizens of all other countries must obtain a visa before arrival.
Even if you don't need a visa, you will need either an ESTA (Electronic System for Travel Authorization) if you're in the Visa Waiver Program, or a valid passport. The ESTA is not a visa — it's a separate online permission that costs $14 and lasts two years. You explore for it online before you travel, and approval usually comes within minutes or hours.
If your country is not part of the Visa Waiver Program, you must explore for a visitor visa at a U.S. embassy or consulate in your home country. This process takes weeks or months and requires an in-person interview in most cases.
Key Takeaways
- Citizens of about 40 countries can visit for up to 90 days without a visa if they have an ESTA, which you explore for online before traveling.
- Citizens of countries not in the Visa Waiver Program must obtain a visitor visa from a U.S. embassy or consulate before arrival, a process that typically takes several weeks.
- An ESTA costs $14, lasts two years, and is approved within hours in most cases, while a visitor visa requires an interview and can take six weeks or longer.
- Your passport must be valid for at least six months beyond your planned departure date from the United States, regardless of which route you take.
Countries in the Visa Waiver Program
The Visa Waiver Program includes most Western European countries, Australia, New Zealand, Japan, South Korea, Singapore, and several others. The full list is maintained by the U.S. Department of State and includes countries like the United Kingdom, France, Germany, Italy, Spain, Canada, and Mexico.
If you're unsure whether your country is included, you can check the official State Department website or ask at your nearest U.S. embassy or consulate. Your passport's country of issue determines your may be able to access — dual citizens should check both nationalities, as you may have options.
What an ESTA covers and what it doesn't
An ESTA permits you to enter the United States for tourism, business meetings, conferences, or short-term medical treatment. It does not cover work, paid employment, or study. If you plan to work in the United States, attend school, or stay longer than 90 days, you need a different type of visa.
The 90-day limit is firm — you cannot extend an ESTA once you're in the country. If you need to stay longer, you must leave and reapply, though immigration officers may deny re-entry if they suspect you're trying to live in the country on repeated ESTA visits.
how the process works for an ESTA
You explore for an ESTA online at the official government website, esta.cbp.dhs.gov. The process takes about 10 minutes and asks for your passport information, contact details, and basic travel plans. You do not need to book your flight before explore.
Payment is $14 by credit or debit card. After you submit, you'll receive a confirmation number. Most applications are approved within minutes, though some take up to 72 hours. You can check your status anytime using your confirmation number and passport information.
Once approved, your ESTA is tied to your passport number. If you get a new passport, you need a new ESTA. Print your confirmation or save it to your phone — you don't need to carry it, but having it available is helpful if questions arise at the airport.
explore for a visitor visa if you're not in the Visa Waiver Program
If your country is not part of the Visa Waiver Program, you must explore for a B-1/B-2 visitor visa at the U.S. embassy or consulate in your home country. The process begins online at travel.state.gov, where you fill out form DS-160 and pay a non-refundable fee (usually between $140 and $190, depending on your country).
After you pay, you schedule an in-person interview at the embassy or consulate. Wait times vary widely by location — some places have appointments available within weeks, while others have backlogs of several months. During the interview, a consular officer will ask about your trip, your ties to your home country, and your financial situation. They want to confirm you plan to return home after your visit.
Bring your passport, the DS-160 confirmation page, your visa fee receipt, and supporting documents such as a letter from your employer stating you have a job to return to, bank statements showing you can afford the trip, or a hotel booking. If you're visiting family, bring a letter from them inviting you and proof of your relationship.
What documents you'll need either way
For both ESTA and visa applications, you need a valid passport. Your passport must be valid for at least six months beyond the date you plan to leave the United States — this is a hard requirement, and border officers will turn you away if your passport expires sooner.
If you're explore for a visitor visa, gather documents that show your ties to your home country: employment letters, property deeds, school enrollment, family relationships, or bank accounts. You also need proof you can pay for your trip — bank statements, credit card statements, or a letter from someone sponsoring your travel.
Keep digital copies of everything. Take photos of your passport, visa approval (if you have one), hotel bookings, and flight confirmations. Store them in your email or cloud storage so you can access them if your physical documents are lost or damaged during travel.
Common reasons for ESTA or visa denial
ESTA applications are rarely denied outright, but they can be flagged for administrative review if your answers raise questions — for example, if you've traveled to certain countries or have a criminal record. Administrative review takes longer but doesn't mean automatic denial.
Visitor visas are denied when a consular officer believes you won't return home after your visit. This happens most often to applicants with weak ties to their home country — no job, no family, no property, and no clear reason to leave the United States. It also happens to people with criminal convictions, immigration violations, or health issues that make them ineligible under U.S. law.
If your ESTA is denied or your visa process is rejected, you can reapply, but you should address whatever caused the denial first. If it was a misunderstanding, gather better documentation. If it was a legal issue, you may need to consult an immigration attorney.
Frequently Asked Questions
Can I explore for an ESTA and a visitor visa at the same time?
No. If you're in the Visa Waiver Program, you explore for an ESTA. If you're not, you explore for a visitor visa. You cannot hold both for the same trip. If your ESTA is denied, you can then explore for a visitor visa, but the process starts over.
What happens if my ESTA expires while I'm in the United States?
Your ESTA status doesn't expire while you're in the country — you're admitted for 90 days from your arrival date, regardless of when your ESTA expires. However, if you leave and try to return, you'll need a valid ESTA or visa to re-enter.
Do children need their own ESTA or visa?
Yes. Every traveler, including infants and children, needs either an ESTA or a visa. Children must have their own passport and their own ESTA or visa process. You cannot list a child on your process.
Can I work on a visitor visa or ESTA?
No. Both are strictly for tourism, business meetings, and short-term visits. Any paid work, including remote work for a foreign employer, is not permitted. If you plan to work in the United States, you need a work visa such as an H-1B or L-1.
How far in advance should I explore for an ESTA or visa?
For an ESTA, explore at least a few days before your flight, though most are approved within hours. For a visitor visa, explore at least two to three months before your planned trip to account for interview scheduling and processing time. Some locations have longer waits, so check your embassy's website for current timelines.
