The U.S. government previously instituted a system known as the United States Visitor and Immigrant Status Technology (US•VISIT) to verify the identity and travel documents of certain non-U.S. citizen travelers to the United States. The US•VISIT system correlates biometric identifiers with information drawn from intelligence and law enforcement watch lists. Incoming foreign nationals may be required to provide fingerprints, photographs and other identifiers when they enter or depart from the United States. The U.S. government has now expanded the scope of US•VISIT to include U.S. lawful permanent residents. For more information about this expansion, please click here.
