It has been said that a pretty face is a passport. But it’s not, it’s a visa, and it runs out fast.

They take there name from post world war II international conventions, aiming to protect war refugees in the future. They act as a substitute for a passport. CTD’s in general require a visa but depending on the country of residence visa-free travel might be possible (just as with regular passports) . In theory all signatories of the convention should accept CTD’s. So can you travel?
