Before ESTA renewal, it is important to know that the current approval is not simply extended and that a new application may be required instead.
Approval is generally valid for two years, but it will expire sooner if your passport expires first.
A new application is also required if you receive a new passport or if key personal details such as your name, gender, or country of citizenship change.
Therefore, before reapplying, please review your passport validity, the information you entered, and your current approval status, and make sure to apply for ESTA before departure.
