Global Entry is a program of the U.S. Customs and Border Protection service that allows pre-approved, low-risk travelers to receive expedited clearance upon arrival into the United States through automatic kiosks at select airports and via the SENTRI and NEXUS lanes by land and sea. As of May 4, 2018[update], Global Entry was available at 53 U.S. airports and 15 preclearance locations.[1][2] By April 2018 more than five million people were enrolled in Global Entry[3] and approximately 50,000 new applications for the program were being filed each month.
