The United States ESTA is an electronic travel authorization that allows eligible travelers to visit the United States without a visa.

Visa-exempt travelers to the US can use this permit instead of a visa. It's easier and quicker to apply for than a regular B1/B2 (tourist) visa and helps the United States government strengthen border security.

All visitors who are visa-exempt travelers to the US can use this permit instead of a visa. Those who require a visa for the United States instead, or those with permission to study, work, or live in the US, don't need the United States ESTA to enter the country.

However, please note they may need another document to enter.

• Um passaporte, válido durante todo o período da sua estadia.
• Um endereço de e-mail para criar a solicitação e receber informações.
• Um cartão de crédito ou débito, ou Apple Pay ou Google Pay.

Once your ESTA is issued, it's valid for 2 years (or until your passport expires), and you can travel to the United States on multiple trips.

Please note: For Brunei or Hungary passport holders, the US travel authorization ESTA is valid for up to 1 year from the date of issuance.

Having an ESTA authorization does not mean you may stay in the US for two years. It only allows you to stay in the US for up to 90 days per visit.
