New rules starting in 2007 regarding requirements for travel to Canada and Mexico. http://www.latimes.com/travel/la-tr-insider14jan14,0,5485427.story?track=tothtml
THE days of passport-free air travel between the U.S. and much of the Western Hemisphere are numbered — and that number is nine.
On Jan. 23, just nine days from now, travelers — Americans included — will need a passport to enter the U.S. by air from Canada, Mexico, Bermuda, Central and South America and most of the Caribbean.
FOR now, the new rules apply only to air travel. Land and sea travelers to the region have until Jan. 1, 2008, to obtain a passport or a new form of identification called a passport card.
The less expensive wallet-size passport card allows for land and sea travel only between the U.S. and Mexico, Canada and the Caribbean. The card cannot be used for air travel.
