Do you need a valid passport to travel from the us to Mexico?

Answer 1

ENTRY/EXIT REQUIREMENTS: For the latest entry requirements, contact the Embassy of Mexico web site at http://portal.sre.gob.mx/usa/ or contact the Embassy of Mexico at 1911 Pennsylvania Avenue NW, Washington, DC 20006, telephone (202) 736-1000 or any Mexican consulate in the United States for the most current information. All Americans traveling by air outside the United States are required to present a passport or other valid travel document to enter or re-enter the United States. This requirement will be extended to sea travel (except closed loop cruises), including ferry service, by the summer of 2009. Until then, U.S. citizens traveling by sea must have government-issued photo identification and a document showing their U.S. citizenship (for example, a birth certificate or certificate of nationalization), or other Western Hemisphere Travel initiative (WHTI) compliant document such as a passport card for entry or re-entry to the U.S. Sea travelers should also check with their cruise line and countries of destination for any foreign entry requirements. The new U.S. Passport Card is now being issued. The card may not be used to travel by air and is available only to U.S. citizens. Further information is available at http://travel.state.gov/passport/ppt_card/ppt_card_3926.html and upcoming changes to U.S. passport policy can be found on the Bureau of Consular Affairs web site at http://travel.state.gov/tr ENTRY/EXIT REQUIREMENTS: For the latest entry requirements, contact the Embassy of Mexico web site at http://portal.sre.gob.mx/usa/ or contact the Embassy of Mexico at 1911 Pennsylvania Avenue NW, Washington, DC 20006, telephone (202) 736-1000 or any Mexican consulate in the United States for the most current information.
