Planning a trip outside the US? You better have a passport.
Starting Tuesday, new rules go into effect that will require travelers to have passports for places like Canada, Mexico and the Caribbean.
For years, just a birth certificate or driver's license was required.
The new rule is a recommendation of the September 11th Commission.
"I think it's a good thing. It will probably help a lot in terms of security. It is no hassle for me; I've had a passport for almost 10 years and will be renewing it soon," explains Patricia Hall, who supports the new passport law.
"I think it's the wave of the future and everyone should just go out and get their passports and get it over with. Like Pat, I already have one, so for me, it's no big deal," explains Barbara Hardy, who is renewing her passport.
If you return to the U.S. without a passport, you will have to undergo a secondary screening to verify your citizenship.
The new law does not limit passports to adults. Children and infants are required to have one as well.
