Vatican has most restrictive immigration policy

Only about 450 of its 800 or so residents actually hold citizenship, according to a 2012 study by the Library of Congress. That study said citizens are either church cardinals who reside in the Vatican, the Holy See’s diplomats around the world, and those who have to reside in the city because of their jobs, such as the Swiss Guard.

Spouses and children who live in the city because of their relationship with citizens — including the Swiss Guard and workers such as the gardener — have also been granted citizenship. But that means few of the Vatican’s citizens are women.

Of course.  Do as I say, not as I do.
