On May 4, 2007, DHS announced that it intends to fully implement biometric screening for exiting visitors as part of the existing international visitor departure process. The DHS had been conducting a three-year pilot program at 14 international airports and was under congressional pressure to roll out the program to all airports. Effective May 6, 2007, the pilot program, which suffered from low compliance, will be completed and international visitors will no longer need to pass through a special kiosk when they leave the United States. The new biometric screening procedures would integrate biometric screening procedures into the existing departure process for international visitors; the exact details of the procedures must be negotiated with the airlines. DHS will publish a regulation outlining its plans for implementing an integrated air exit strategy.
