What visas do you need to have when going on an Alaskan cruise?

When going on an Alaskan cruise, the type of visa you need depends on your nationality and the ports of call included in your itinerary. If you are a citizen of a country that requires a visa to enter the U.S., you will need a valid U.S. visa, particularly if the cruise starts or ends in a U.S. port. Additionally, if your cruise includes stops in Canada, you may need a Canadian eTA (Electronic Travel Authorization) or visa. Always check the specific requirements based on your nationality and planned route before your trip.
