Passport Rules Relaxed In Advance Of Summer Travel Season

MIAMI - JUNE 22: A Customs and Border Protection officer checks passports at the passport control booth as they enter the United States through the Miami International Airport June 22, 2007 in Miami, Florida. The Bush administration postponed for at least six months a requirement that Americans who return to the United States by land or sea from Canada, Mexico and the Caribbean must carry passports. The rule, due to go into effect in January 2008, will be delayed until the summer of that year. (Photo by Joe Raedle/Getty Images)
