The Global Entry Mobile Application allows eligible Trusted Travel Members to submit their travel document and photo through a free, secure app on their smartphone or other mobile device. The use of Global Entry Mobile Application streamlines the traveler’s entry process into the United States by reducing passport control inspection time and overall wait time. Use of Global Entry Mobile Application does require a valid Trusted Traveler Membership. Travelers who successfully use the application will no longer have to use a portal or kiosk. As a result, travelers may experience shorter wait times, less congestion and efficient processing.
