U.S. Will Tighten Passport Rules

Millions of Americans will be required to show passports when they reenter the United States from Canada, Mexico and the Caribbean by 2008 under new rules announced yesterday by the State and Homeland Security departments.

The new policy, designed to thwart terrorists from exploiting the relative ease of travel in North America, means that Americans who lack U.S. passports will have to obtain them to travel between the United States and neighboring nations. It also will require Mexicans and Canadians to present either passports or another official document to enter this country, with details to be determined.

Currently, U.S. citizens in most cases need to show only driver’s licenses to reenter this country from Mexico and Canada, though officials said that since the Sept. 11, 2001, attacks, some officials at border crossings at times have asked for additional documents.
