I am taking a cruise to Mumbai very soon. I saw in one of your forums that visa is not required if I stay on board and not getting off the boat. I contacted Princess and they insisted that I require a visa since I am in Indian waters and I have the capability of getting into India. Can you confirm that visa is not required if I do not leave the boat? Where can I get something in writing to show Princess in case they refuse me entry onto the boat from Sydney? I am Australian.
