The U.S. Departments of Homeland Security (DHS) and State (DOS) announced on Feb. 26, 2009 that their efforts have enabled the departments to jointly certify to Congress that all statutory criteria have been met prior to implementing the Western Hemisphere Travel Initiative (WHTI) at land and sea borders on June 1, 2009. WHTI is a joint DHS-DOS plan to implement a core 9/11 Commission recommendation, which Congress subsequently passed into law in the Intelligence Reform and Terrorism Prevention Act of 2004. Upon implementation of WHTI, travelers will be required to present a single WHTI-compliant document denoting both citizenship and identity when seeking entry into the United States through a land or sea border. The WHTI secure document requirement is already in place for all air travelers, and applies to travelers entering the United States who were previously exempt, including citizens of the U.S., Canada and Bermuda.Source: DHS press release; find full text here>>.
