Yes, you generally go through passport control on a cruise, but the process is often more streamlined than at an airport. In 2026, the European Union's Entry/Exit System (EES) has modernized this for many travelers; at major ports, your biometrics (facial scan and fingerprints) are recorded digitally rather than having a physical stamp placed in your passport. For "closed-loop" cruises (starting and ending at the same U.S. port), U.S. citizens can often use a birth certificate and government ID, but a passport is still the "gold standard" for a seamless re-entry. During the cruise, the ship's crew typically handles the manifest with local authorities at each port, so you often only face a physical "face-to-face" check with customs officials during the final disembarkation at the end of your voyage.
