Hot tip: Get your passport ASAP

Been putting off getting that passport? Now is the time to get yourself in gear.

Beginning Jan. 8, 2007, all travelers except cruise ship passengers returning to the United States from the Caribbean, the Bahamas, Canada, Central America, Mexico and Bermuda must have a passport. Previously, only a birth certificate and photo I.D. were required.

If you're cruising, you've got until 2008 to get your passport. But it's smart to act now: In an emergency, you might need to fly home … and for that you'll need a passport.

Apply in person at many U.S. Post Offices. You'll need the application form, proof of citizenship (U.S. birth certificate or naturalization certificate), two color passport photos and valid photo ID. Children under 14 require consent of both parents or legal guardians. For info and forms, see the U.S. State Department website.

Processing time currently runs up to six weeks. Cost: $97 ages 16 and up, $82 for under 16.

If your existing passport is expiring, note that most foreign governments require at least six months remaining on your documents. If you have a valid passport, you can renew by mail. Cost: $67.

If you have to leave the country within the next two weeks, you can contact the Miami Passport Agency, 877-487-2778. You must make an appointment.

No Caribbean plans? Get your passport anyway. You never know when someone will invite you to breakfast … in Buenos Aires.
