DHS reminds travelers that beginning January 31, 2008, border crossers will be asked to present documents denoting citizenship and identity when entering the United States through land and sea ports of entry. This change primarily affects United States and Canadian citizens, who have previously been permitted entry by oral declaration alone, and marks the transition toward standard and consistent documents for all travelers entering the country. It is also the start of a more robust and concerted public education campaign, intended to inform travelers of document requirements which will be implemented next year.
