how much is an esta

The current cost to apply for an ESTA (Electronic System for Travel Authorization) is $21 per application if done through the official ESTA website. This fee includes a $4 processing fee and a $17 fee for approved applications. If the application is rejected, the applicant still pays the $4 processing fee. The ESTA is valid for two years or until the passport expires, whichever comes first. Note that each traveler, regardless of age, needs a separate ESTA, including children and babies. There has been a planned price increase to $40, but as of now, the fee remains $21 for new applications.
