Welcome to LCT Scott, Boy do we need to add this to the list of things missing off RSSC's new website. The catalogs/brochures and website used to very explicitly state what visas were required. In fact on the website, for cruises that required visas they used to have a link to ZVS with a password and you could go there and look for your specific Regent cruise and find all the application forms, prices, wait periods, etc. (You did not have to use the Zierer service, but it was an excellent information source for every RSSC cruise.) BUT, I just checked since you asked and all of that is gone! Sadly, I no longer remember what the RSSC password (like a 5 to 7 digit number?) was either to just check the ZVS website. Sorry. I hope that someone else has an RSSC answer to their obligations. Yes, we are all individually responsible for obtaining our own travel documents, but in my mind every cruiseline bears the responsibility of informing their paying customers what they will require you to present to board the ship. In the absence of any RSSC information about visa requirements, I would recommend that you visit the embassy or consulate websites of each country you will visit on the cruise. For US citizens, you can find that from the State Dept. link below.
