According to a DHS Press Release from April 22, 2008: “The U.S. Department of Homeland Security (DHS) announced today a notice of proposed rulemaking that will establish biometric exit procedures at all U.S air and sea ports of departure. The majority of the Canadians are already required to submit digital fingerprints and a digital photograph for admission into the country.* The US-VISIT Exit proposal would require non-U.S. citizens who provide biometric identifiers for admission to also provide digital fingerprints when departing the country from any air or sea ports of departure.”
