▶ ESTA (ELECTRONIC SYSTEM FOR TRAVEL AUTHORIZATION) is an online system under the U.S. Visa Waiver Program (VWP) that allows citizens of designated countries to travel to the United States for tourism, business, medical treatment, or transit without obtaining a visa. Travelers must apply online and receive approval prior to boarding a flight or ship bound for the United States.
▶ All travelers entering the United States under the Visa Waiver Program must obtain an approved ESTA authorization before departure.
Currently, nationals of 42 countries are eligible for visa-free entry through the Visa Waiver Program (VWP).
Citizens of non-VWP countries must apply for a visa at a U.S. Embassy or Consulate.
▶ ESTA approval is generally valid for two years from the date of issuance, unless your passport expires earlier or your personal information changes (such as name, gender, nationality, or passport number).
If any key personal information changes, you must submit a new ESTA application.
▶ Once an application has been submitted, it cannot be modified.
If incorrect or false information is entered, the applicant must reapply for ESTA with accurate details.
If the information on your ESTA application does not exactly match your passport information, you may not be allowed to board your flight or ship.
Therefore, please carefully review all information before making your final payment.
▶ The following travelers are exempt from ESTA requirements:
- Holders of valid U.S. visas (e.g., B1/B2, F1, H1B, etc.)
- U.S. citizens and U.S. lawful permanent residents (Green Card holders)
- Individuals traveling to the United States with a visa issued by a U.S. Embassy or Consulate
- Crew members traveling under C1/D visa status
- Travelers entering the U.S. via land from Canada or Mexico (ESTA is not mandatory for land crossings, though recommended for air or sea re-entry)
- Diplomatic or official passport holders traveling on government missions
- United Nations (UN) Laissez-Passer holders traveling on official duty
▶ Important Notes
- Transit passengers who intend to enter the U.S., even briefly, must have a valid ESTA authorization.
- ESTA approval does not guarantee entry. Final admission decisions are made by U.S. Customs and Border Protection (CBP) officers at the port of entry.
- Travelers who overstay or violate VWP terms may be denied future ESTA approvals and must apply for a visa instead.
- Application fees are non-refundable, regardless of approval or denial.
