who is allowed to live in vatican city
Vatican City Almost all of Vatican City's more than 450[72] citizens either live inside the Vatican's walls or serve in the Holy See's diplomatic service in embassies (called "nunciature"; a papal ambassador is a "nuncio") around the world. The Vatican citizenry consists almost entirely of two groups: clergy, most of whom work in the service of the Holy See, and a very few as officials of the state; and the Swiss Guard. Most of the 2,400 lay workers who comprise the majority of the Vatican workforce reside outside the Vatican and are citizens of Italy, while a few are citizens of other nations. As a result, all of the City's actual citizens are Catholic as are all the places of worship.
