Do I need a passport to travel to Mexico?

in 2007 you will.

yes.

If you are flying then in January you will - especially to get back into USA. If you are driving or on a cruise then you will not have to have one until January 2008.

It is always safer to have one and you will anyways for a later date - might as well do it now...its good for 10 years.

As of January 22, 2007, all travelers entering the USA will need a passport. This includes Americans returning from abroad. It was always that one could travel to nearby countries like Bermuda, The Bahamas, Mexico and just show picture ID and a birth certificate. That all changes in January.

It is better if you do and after January 23, 2007 you will need it to come back to US if you are traveling by air.

Here is the info from the US Department of State:

ENTRY REQUIREMENTS: The Government of Mexico requires that all U.S. citizens present proof of citizenship and photo identification for entry into Mexico. However, some U.S. citizens have encountered difficulty in boarding flights in Mexico without a passport. The U.S. Embassy recommends traveling with a valid U.S. passport to avoid delays or misunderstandings. A lost or stolen passport is easier to replace when outside of the United States than other evidence of citizenship. However, U.S. citizenship documents such as a certified copy (not a simple photocopy or facsimile) of a U.S. birth certificate, a Naturalization Certificate, a Consular Report of Birth Abroad, or a Certificate of Citizenship are acceptable. U.S. citizens boarding flights to Mexico should be prepared to present one of these documents as proof of U.S. citizenship, along with photo identification, such as a state or military issued ID. Driver's licenses and permits, voter registration cards, affidavits and similar documents are not sufficient to prove citizenship for readmission into the United States.

IMPORTANT NEW INFORMATION: Effective January 23, 2007, all U.S. citizens traveling by air to and from the Caribbean, Bermuda, Panama, Mexico and Canada are required to have a valid passport to enter or re-enter the United States. As early as January 1, 2008, U.S. citizens traveling between the United States and the Caribbean, Bermuda, Panama, Mexico and Canada by land or sea (including ferries), may be required to present a valid U.S. passport or other documents as determined by the Department of Homeland Security. American citizens can visit travel.state.gov or call 1-877-4USA-PPT (1-877-487-2778) for information on applying for a passport.

depending on where u live but i in america u need a passport 2 change borders if u want more info look it up on internet my best bet.but yea u need 2 a passport 2 go mexico depending where u are

If you are a U.S. citizen, currently you do not. Current plans (which may be revised further) will require that in 2007 ALL air passengers arriving from any other country (including Canada and Mexico) will require passports to land in the U.S.A. (So technically you wouldn't need a passport to go TO Mexico, but you would need one to return by air.) Under the new rules you would still be able to visit Mexico via a land border without a passport. You will still need proof of citizenship, and if you plan to drive your own car across the border you will need Mexican automobile insurance.

Not at present. After mid January you will need one to fly to Mexico and after jan. 1, 2008 you will need one to travel there via land. You will need a visa to go there other than by cruise ship or one of the border towns which is simply a matter of paying for one. Understand that any minor also need to be in possession of a notorized letter giving permission to travel there by any absent parent, or both of them is neither accomplines the minor. The only exception is if the absent parent is deceased, and you must have a copy of the death certificate. or you have an official court decree excusing the absent parent from any responsibility or claims of parenthood.

if you re Mexican no
