Want to speed up your time through passport control when returning from an overseas trip?  Global Entry is a U.S. Customs and Border Protection (CBP) program that allows expedited clearance for pre-approved, low-risk travelers upon arrival in the United States. Though intended for frequent international travelers, there is no minimum number of trips necessary to qualify for the program. Once approved, you will be able to enter the United States by using automated kiosks located at select airports. Just present your machine-readable passport or U.S. permanent resident card, place your fingertips on the scanner for fingerprint verification, and make a customs declaration. The kiosk will issue you a transaction receipt and direct you to baggage claim and the exit.  You must first be pre-approved for the Global Entry program. All applicants undergo a rigorous background check and interview before enrollment and families can apply.
