Do you need a passport to take a cruse to Mexico?
At present you are good to go with a proof of citizenship like your birth certificate and a government issued picture ID like your driver’s license. Starting Juni 1, 2009 you will need a passport, a passport card, or an enhanced driver’s license also denoting the citizenship for sea travel too. As exception birth certificate and driver’s license may continue to be used on closed-loop cruises with the same U.S. port for departure and arrival. However it is strongly recommended to obtain a passport for these type of travel since a flight repatriation in case of an accident or severy illness would not be possible without it.
