According to U.S. law, you can set sail and then disembark at a foreign port. However, although it is allowed by U.S. law, there are still foreign laws and cruise line policies to contend with. In some countries, laws prohibit cruise passengers from permanently disembarking.

Yes, you can technically get off a cruise ship and stay at a port, but in 2026, this is usually referred to as "terminating your cruise early" or "downlining," and it requires prior authorization. You cannot simply walk off with your luggage and not return without notifying the ship, as this triggers a massive security and search-and-rescue response. If you wish to leave the ship permanently at a port of call, you must submit a request to the Guest Services desk at least 48 to 72 hours in advance. This is subject to the Jones Act (in the US) or local cabotage laws, which may impose fines if you are transported between two domestic ports by a foreign-flagged vessel. Furthermore, once you leave, you are responsible for your own transport home and will not receive a refund for the remaining days. If you just want to stay overnight and rejoin the ship at the next port, this is also possible but requires strict coordination to ensure you meet the ship’s immigration and customs requirements at the subsequent destination.
