Mobile Passport Control is a Global Entry alternative that allows many international travelers arriving in the US to skip the long customs line for free.
  • Mobile Passport Control lets travelers skip customs lines with a free app on their phone.
  • The app, available since 2014, is underused despite being available at 33 major US airports.
  • Global Entry is faster and more widely used but costs $100 and requires an interview.

Global Entry isn't the only way international travelers can skip long lines at US Customs and Border Protection (CBP).
