Effective June 1, 2009, the following rules take effect for cruise passengers:

U.S. citizens on cruise voyages that begin and end at the same U.S. port (closed-loop itineraries) must show proof of citizenship* and government-issued photo ID (such as a driver’s license). A passport will not be required for passengers that fall into this category.

*Documents include: Original or certified copy of birth certificate; Naturalization papers; Consular Report of Birth Abroad issued by Department of State.  For detailed information, please visit http://www.cbp.gov/xp/cgov/travel/vacation/ready_set_go/sea_travel/

All other passengers and/or itineraries (such as cruises which begin in one U.S. port and return to a different U.S. port or any cruise that begins or ends in a foreign port) will require a passport or other recognized document. For a list of accepted documents, see http://www.travel.state.gov/ .
