Air travelers entering the United
States from countries in the Western Hemisphere will be required to
present a passport beginning Jan. 23. The rule applies to citizens
of the United States, Canada, Mexico and Bermuda who were
previously admitted with a driver's license or birth certificate.
The only acceptable passport alternatives will be the Merchant
Mariner Document (MMD), United States military ID (if the holder is
traveling on official orders), or the NEXUS Air Card, which is
currently granted only to prescreened, low-risk frequent travelers
who are part of a pilot program at Vancouver International Airport
and are permanent residents of the United States or Canada. A
passport requirement for land and sea ports of entry from Western
Hemisphere countries is planned for as early as Jan. 1, 2008.
