Vatican City is ruled by the Pope
Vatican City, officially the Vatican City State, is a landlocked sovereign state and city-state. It is the smallest country in the world, covering just over 100 acres, with a population of about 800 people. It is nestled inside Rome, Italy, and is the seat of the Catholic Church.
Vatican City is an ecclesiastical or sacerdotal-monarchical state ruled by the Pope. The Pope is the head of state of the Vatican City State and has been since 1929. The Pope delegates executive authority to the President of the Pontifical Commission for Vatican City State, who is appointed by the Pope for a five-year term. The President of the Pontifical Commission is also the President of the Governorate of Vatican City, to whom the Pope delegates executive authority for the state. The Pope's legislative authority for the state is delegated to the Pontifical Commission for Vatican City State, which consists of seven Cardinals appointed by the Pope for five-year terms.
The Holy See, which is the government of the Roman Catholic Church, resides in Vatican City and is led by the Pope as the bishop of Rome. The Holy See's authority extends over Catholics worldwide. The Holy See and the Vatican City State are two separate subjects of international law, both presided over by the Pope.
Vatican City has a unique citizenship law, with citizenship granted only to those who reside and work for the Vatican office. Cardinals who live in Vatican City or Rome, as well as diplomats of the Holy See, are considered citizens. Vatican citizenship is lost when the term of office ends, and it cannot be inherited by children.
While Vatican City is ruled by the Pope, not all citizens of Vatican City are Catholic. There are strict rules and regulations concerning citizenship, and only about 450 of the 800 residents have Vatican citizenship.

Vatican City is a city-state with unique citizenship laws
Vatican City, the smallest country in the world, is a unique city-state ruled by the Pope. It has a population of about 800 people, of which only about 450 have Vatican citizenship. The rest are mostly tourists, with some locals who follow the strict rules and regulations of the land.
Vatican citizenship is quite distinct from that of other countries. It is not based on birthright or blood relations but is granted to those who reside and work in Vatican City. Cardinals who live in the Vatican City or Rome and diplomats of the Holy See are also considered citizens. Interestingly, children of citizens cannot inherit citizenship, and it is lost when they turn 18. Similarly, in the event of a divorce, the spouse who acquired citizenship through marriage loses their status as a citizen.
The Pope, as the ruler of the Vatican City State, has the power to grant citizenship to those authorised to reside permanently in the Leonine City. Citizenship can also be acquired by law or administrative decision. Ex iure citizenship is granted to three classes of people: cardinals resident in the Vatican City State or Rome, members of the Swiss Guard, and persons who reside in the Vatican City State due to their office or service.
The Vatican City State law on citizenship, residence, and access, promulgated on February 22, 2011, classifies citizens into three categories. The first two categories do not require citizenship, while the third category, persons residing in Vatican City because of their office or service, requires an actual grant of citizenship.
To apply for Vatican City citizenship, applicants must be Roman Catholic and have a special relationship with the Holy See. They must also demonstrate knowledge of Italian culture and customs. The Vatican passport is a powerful travel document, allowing visa-free access to many countries worldwide.

Diplomatic passports of the Holy See are held by those in its diplomatic service, while service passports can be issued to non-citizens in the service of the Holy See. Vatican City passports are issued to citizens who are not in the service of the Holy See. As of 2 July 2019, Vatican citizens had visa-free or visa-on-arrival access to 148 countries and territories.
While Vatican City is the centre of the Roman Catholic Church, one does not have to be Catholic to attend the Pope's services. However, some have suggested that if the Vatican offered dual citizenship to all Catholics, there would be no refugees in the Catholic Church.

Citizenship is not based on birthright or blood
Vatican City is the smallest country in the world, with a population of about 800 people. It is a city-state ruled by the Pope and is located within Rome, Italy. While it is the symbolic centre of the Roman Catholic Church, not all citizens of Vatican City are necessarily Catholic. In fact, citizenship in Vatican City is not based on birthright or blood but is granted based on other factors.
The unique nature of Vatican City as a sovereign state within a city means that traditional factors for acquiring citizenship, such as ius sanguinis (right of blood) or ius soli (right of the soil), do not apply. Instead, Vatican City has established its own criteria for citizenship, which are more appropriate for its structure and political organisation.
Citizenship in Vatican City is primarily granted to those who reside and work for the Vatican office or hold office in the Holy See, the universal government of the Catholic Church. Cardinals who live in Vatican City or Rome and diplomats of the Holy See are also considered citizens. It is important to note that Vatican citizenship is lost when the term of office ends, and children cannot inherit it from their parents.
There are approximately 450 citizens of Vatican City, and about 135 of them are Swiss Guards. The Vatican City State law on citizenship, residence, and access, promulgated on 22 February 2011, classifies citizens into three categories. The first category includes those who hold office in the Vatican or Holy See. The second category comprises those who reside in Vatican City due to their office or service, including the Swiss Guards. Only the third category requires an actual grant of citizenship.
In addition to the three main categories, Vatican citizenship can also be extended to the spouse, children, ascendants, and siblings of a Vatican citizen, provided they live with the citizen and are authorised to reside in Vatican City according to the established norms. The different types of passports issued by the Vatican and the Holy See reflect the complex relationship between these entities and the unique nature of Vatican citizenship.
