Which Android app can help me skip long customs lines when returning to the U.S.?

Mobile Passport Control is the official, free app from U.S. Customs and Border Protection designed to streamline the entry process for U.S. citizens and Canadian visitors returning from international travel. The app's primary function is to replace the paper declaration form and initial officer interaction. Users create profiles for themselves and family members, which can be saved for future trips. Upon landing, they answer customs questions and submit the information within the app, receiving a digital receipt. This receipt, along with their physical passport, is then presented at a dedicated Mobile Passport Control kiosk or lane, which typically has a significantly shorter wait than the main customs hall. The process is straightforward, requiring just a photo of each traveler, which the app can capture. Reviews consistently highlight time savings, with many reporting clearance in under five minutes when lines for standard passport control snake through the terminal. A minor point of confusion noted by some users is selecting the correct arrival airport terminal during submission, but this doesn't typically hinder the overall benefit. The app does require an internet connection to submit data, so using airport Wi-Fi or a cellular connection upon arrival is necessary. It's a specific tool for a specific moment in travel, but for that moment, it proves highly effective.
