The U.S. Customs and Border Protection agency has rolled out their Global Entry program to speed up the customs process at some U.S. airports. To join the program, you pay $100, pass a government background check, and get fingerprinted. Then, you can use a kiosk instead of waiting in line for a customs agent.
At Washington Dulles (IAD), the average processing time at peak hours (using human agents) is one hour. Using the Global Entry machines, that average time is reduced to one minute and four seconds.
If you’ve got goods to declare, you must then go through normal inspection. Some travelers will be spot checked the old fashioned way.
