Information received from the Department of Homeland Security indicates the documentary requirements under WHTI for “closed loop” cruises are not limited to cruises that travel only to contiguous territories or adjacent islands. This means U.S. citizens calling on ports in Honduras, Panama, Costa Rica and Belize will also be exempt from the passport requirement.
Children are also required to bring proof of citizenship, and if 16 and over, a photo ID is also required. Canadian and Bermudian citizens are required to have a passport for air, land and sea travel, including on all cruises.
For more information, a complete list of WHTI-compliant documents or to obtain a passport application, visit www.travel.state.gov. U.S. Alien Residents need a valid Alien Resident Card. Non-U.S. citizens need a valid passport and a valid, unexpired U.S. Multiple Re-entry Visa, if applicable.
