Mexico, Canada to U.S.? Passport Now Required

May 31, 2009— -- If you're planning to travel to Mexico or Canada next week, be prepared to show the proper identification.

Starting Monday, the last implementation stage of the Western Hemisphere Travel Initiative will go into effect, requiring travelers to present a passport or other valid travel document when entering the U.S. by land or sea.

The requirements were put into place by the Bush administration in the aftermath of the Sept. 11, 2001, terrorist attacks. While parallel provisions for air travel went into effect in January 2007, this stage of implementation for land and sea travel was delayed because the government feared Americans were not adequately prepared.

Previously, Americans returning from Canada by land had to present a driver's license and birth certificate to prove identification and citizenship. But as of June 1, Americans will need to present a valid travel document to enter the U.S. from Canada, Mexico, the Caribbean islands and Bermuda.

What's a valid travel document? A regular passport, a new passport card, a "trusted traveler" card or an "enhanced driver's license," which states the person's nationality. Children under the age of 16 will not be required to have the travel documentation.

Currently, only a handful of states -- Vermont, New York, Washington and Michigan -- offer the new enhanced documentation.

Enhanced driver's licenses are wallet-size and are less expensive than the average $100 fee for a standard passport.

Officials hope the provisions, which invalidate birth certificates and drivers' licenses as forms of identification, will help set a more uniform standard for border travel, creating a safer and more efficient travel experience.

With summer ahead, the new regulations have potential to thwart many travel plans.
