It is not a visa, it allows stays of up to 90 days, and it only applies to travelers from participating countries.

What ESTA Is
ESTA is an online authorization that pre-screens travelers who want to visit the U.S. under the Visa Waiver Program. It is required before you board a flight or ship to the United States as a VWP traveler, and it is administered by U.S. Customs and Border Protection.
Importantly, ESTA is not a visa and does not guarantee entry. It is permission to travel to a U.S. port of entry, where a CBP officer still makes the final admission decision, similar to how a visa works.
Who Can Use ESTA
ESTA is only for citizens of countries in the Visa Waiver Program. These are specific countries whose nationals can visit the U.S. for short business or tourism trips without first obtaining a visa, provided they get an approved ESTA.
If your country is not in the VWP, ESTA is not available to you, and you generally need a B-1/B-2 visitor visa instead. Turkey, for example, is not a Visa Waiver Program country, so Turkish citizens use a visitor visa rather than ESTA.
How to Apply
You apply for ESTA online through the official CBP ESTA website, entering your passport, biographic, and travel information and answering eligibility questions. There is a fee, and most applicants receive a decision quickly, though you should apply well before travel.
| Step | What to do |
|---|---|
| Apply online | Use the official CBP ESTA website |
| Provide details | Passport, travel, and eligibility information |
| Pay the fee | Submit the required fee |
| Get the decision | Often quick, but apply before booking travel |
Use only the official government site, since unofficial sites may charge extra. Apply early, because approval is not guaranteed and a denial means you would need a visa.
Validity and Stay Length
An approved ESTA is generally valid for two years, or until your passport expires, whichever comes first. During that time, you can make multiple trips, each for up to 90 days for business or pleasure.
The 90-day limit is firm, and the Visa Waiver Program generally does not allow extensions of stay or changes of status. This makes ESTA suitable for short visits, not for longer or open-ended plans.
Planning a longer stay or a purpose beyond tourism? ESTA may not fit, and a visa could be needed. Ask Atlas Legal to advise.
ESTA vs a Visa
ESTA and a visa serve similar purposes but differ in key ways. ESTA is a quick online authorization for VWP travelers making short visits, while a visa is obtained through a consular application and interview and can cover a wider range of purposes and longer stays.
The Visa Waiver Program is convenient but limited, especially on stay length and the inability to extend or change status. Our guide on ESTA or a tourist visa compares the two in detail.
Ne Zaman Bir Göçmenlik Avukatıyla Çalışmalısınız?
ESTA is designed to be simple, but questions arise. Legal help is valuable when you are unsure whether your country participates, when a past issue might affect eligibility, when your plans exceed a short visit, or when an ESTA was denied and you need a visa. An attorney can advise on the right path for your situation. Outcomes depend on the facts of each case.
Sıkça Sorulan Sorular
What is ESTA?
ESTA is the Electronic System for Travel Authorization, an online pre-screening approval that citizens of Visa Waiver Program countries need before traveling to the U.S. for short visits without a visa. It is not a visa and does not guarantee entry; a CBP officer still decides admission at the port of entry. It allows stays of up to 90 days for business or tourism.
Is ESTA the same as a visa?
No. ESTA is an online authorization for Visa Waiver Program travelers making short visits, while a visa is obtained through a consular application and interview. Both allow you to travel to a U.S. port of entry, where an officer decides admission, but a visa can cover more purposes and longer stays. ESTA is limited to 90-day visits and generally cannot be extended or changed.
Who needs an ESTA?
Citizens of Visa Waiver Program countries need an approved ESTA to travel to the U.S. for short business or tourism trips without a visa. If your country is not in the VWP, ESTA is not available to you, and you generally need a B-1/B-2 visitor visa instead. For example, Turkey is not a VWP country, so Turkish citizens use a visitor visa rather than ESTA.
How long is an ESTA valid?
An approved ESTA is generally valid for two years, or until your passport expires, whichever comes first. During that period you can make multiple trips, each up to 90 days for business or pleasure. If you get a new passport or your circumstances change, you may need a new ESTA. The 90-day per-trip limit applies regardless of the two-year authorization.
How long can I stay in the U.S. on ESTA?
You can stay up to 90 days per visit under the Visa Waiver Program. This limit is firm, and the program generally does not allow extensions of stay or changes of status. If you need more time or a different purpose, ESTA is not suitable, and you would need an appropriate visa. Plan your trip to fit within the 90-day window.
Can Turkish citizens use ESTA?
No. Turkey is not a Visa Waiver Program country, so Turkish citizens cannot use ESTA. Instead, they generally apply for a B-1/B-2 visitor visa through a U.S. embassy or consulate for short business or tourism trips. The visa process involves an application and usually an interview. If you are a Turkish citizen planning to visit the U.S., a visitor visa is the standard route.
Does ESTA guarantee entry to the U.S.?
No. Like a visa, an approved ESTA lets you travel to a U.S. port of entry, but a CBP officer makes the final admission decision. You can be questioned and, in some cases, denied entry even with a valid ESTA. Being honest about your purpose and prepared to show it is temporary helps, since the officer must be satisfied you qualify for admission.
How do I apply for ESTA?
You apply online through the official CBP ESTA website, entering your passport, biographic, and travel details and answering eligibility questions, then paying the fee. Most applicants get a decision quickly, but apply well before you book travel, since approval is not guaranteed. Use only the official government site, as unofficial sites may charge extra for the same service.
Alt satır
ESTA is an online travel authorization for Visa Waiver Program travelers, not a visa, allowing short visits of up to 90 days and generally valid for two years.

Each case depends on its own facts.
