Getting a tourist visa to certain countries can be almost impossible—without the right approach.
To even visit Russia, China, Saudi Arabia, Iran, Americans need a “Letter of Invitation."

Travel host Rick Steves says hotels and tour operators usually provide these letters.
Steves says it's also best to ask if all the destinations can be included in one letter!
