Well he's kinda pope till he dies so I'd count that as a permanent residence!
Here's what I found on Wiki:
QUOTE
Citizenship of the Vatican City is granted iure officii, which means it is conferred upon some of those who have been appointed to work in certain capacities at the Vatican, and it is usually revoked upon the termination of their employment. During the period of employment citizenship may also be extended to a Vatican citizen's spouse (unless the marriage is annulled or dissolved, or if a conjugal separation is decreed) and children (until, if they are capable of working, they turn 25, or in the case of daughters, if they marry).
I realise just cos they have citizenship that they might not be permanent residents, but wouldn't some pretty much be living there till they died? Or would they have another status anyway?
...And yes, the answer to my riddle was Vietnam
