Although the Vatican City is home to approximately 1,000 residents no one is born there. This sounds like a riddle doesn’t it? Unlike most other countries in the world, citizenship in Vatican City isn’t solely provided to people that are born in the country. As there are no hospitals in the Vatican State, virtually no one is born in there. Instead, Vatican citizenship is provided on a ‘jus officii’ basis. This means someone is made a citizen of the Vatican when they are appointed to work in the Holy See. Their citizenship ends when their appointment ends. These Vatican residents are given Vatican passports to use during the duration of their residency.
