The ESTA Mobile app, developed by the US Customs and Border Protection, offers a hassle-free way for Nationals of Visa Waiver Program (VWP) countries to apply and pay for a travel authorization without a visa. This mobile version of the ESTA application process provides the same information and functionality as the ESTA website.

The app features two main functions. The "GET STARTED" feature allows travelers to easily create a new ESTA application, complete the payment process, and submit their application for processing. The system will then determine if they are eligible to travel to the United States under the Visa Waiver Program without a visa and provide an automated response. The "FIND IT" feature enables travelers to conveniently check the status of their existing ESTA application.

To ensure a smooth travel experience, it is recommended to apply for ESTA at the time of booking, with a minimum of 72 hours prior to boarding. With the ESTA Mobile app, travelers can conveniently manage their travel authorization process on their iPhone, making it easier than ever to navigate the Visa Waiver Program requirements.
