Your next trip across the border could require some special identification first.
Starting January 23rd, you'll need a passport to return to the U.S. if you're travelling by air.
Experts like travel agent Kathy Baldwin say it's still a critical form of ID to have on hand... Even if you travel by land or sea. "Let's say you board a cruise in Galveston and you're gonna do seven nights and something happens back home. You have to come back home because someone's sick, there's a death in the family, or you get sick on the ship and they have to evacuate you." In case of an emergency, you will want to have a passport on hand so you can board a plane.
The new passport law grew out of recommendations from the 9-11 Commission.
