Citizenship By Birth

''Jus soli'' ( or , ), meaning 'right of soil', is the right of anyone born in the territory of a state to nationality or citizenship. ''Jus soli'' was part of the English common law, in contrast to ''jus sanguinis'' ('right of blood') associated with the French Civil Code of 1804.

''Jus soli'' is the predominant rule in the Americas; explanations for this geographical phenomenon include: the establishment of lenient laws by past European colonial powers to entice immigrants from the Old World and displace native populations in the New World, along with the emergence of successful wars of independence movements that widened the definition and granting of citizenship, as a prerequisite to the abolishment of slavery since the 19th century.

There are 35 countries that provide citizenship unconditionally to anyone born within its national borders. Some countries outside the Americas with mixed systems extend ''jus soli'' citizenship on a limited basis to children who are not otherwise eligible for any national citizenship, such as children born to women who are unwed or from countries that do not recognize maternal ''jus sanguinis'' citizenship. Others impose a residency requirement requiring parents to live in the country for a certain number of years before children born in the country become eligible for conditional ''jus soli'' citizenship. These mixed systems were implemented to fulfill treaty obligations after the atrocities of World War II increased awareness about the vulnerability of stateless persons.

Background

Jus soli, sometimes called ''lex soli'', is the principle of citizenship acquired by the place of birth. Children born to a parent in the diplomatic or consular service of another state are often not eligible for ''jus soli'' citizenship in a host State.

Unconditional ''jus soli'' is mostly found in the Americas. Some countries outside the Americas with mixed systems extend ''jus soli'' citizenship on a limited basis to children who are not otherwise eligible for any national citizenship, such as children born to women who are unwed or from countries do not recognize maternal ''jus sanguinis'' citizenship. Others impose a residency requirement requiring parents to live in the country for a certain number of years before children born in the country become eligble for conditional ''jus soli'' citizenship. UNHCR gives ten reasons for why people become stateless including laws related to marriage, administrative practices, renunciation of citizenship and nationality laws that discriminate on the basis of gender.

Reduction of statelessness

Countries that have acceded to the 1961 Convention on the Reduction of Statelessness are obligated to grant nationality to people born in their territory who would otherwise become stateless persons. These mixed systems were implemented to fulfill treaty obligations after the atrocities of World War II increased awareness about the vulnerability of stateless persons.

The American Convention on Human Rights similarly provides that "Every person has the right to the nationality of the state in whose territory he was born if he does not have the right to any other nationality."Lung-chu Chen,
, -''An Introduction to Contemporary International Law: A Policy-Oriented Perspective'' (Oxford University Press, 2015), p. 223.

Birthright citizenship

The ''New Oxford American Dictionary'' defines birthright citizenship as "a legal right to citizenship for all children born in a country's territory, regardless of parentage". In the United States ''jus sanguinis'' is not a constitutional right or a birth right.Comparative Constitutional Law. United Kingdom: Edward Elgar, 2011. Citizenship by ''jus sanguinis'' is a legal status conferred by statute. The term birthright citizenship usually means ''jus soli'' citizenship.

Birthright citizenship is rooted in colonial history when settlers born in the colonial United States were considered "natural born" subjects of the King of England. The idea of conferring citizenship based on being born within the borders of the United States comes from this history. Allegiance based on natural law principles was the core concept of citizenship in ''Calvin's Case'' in which Edward Coke said that "they that are born under the obedience, power, faith, ligealty or ligeance of the King are natural subjects and no aliens". The American concept of citizenship is derived from republican principles and may have been influenced by the French writer Emer de Vattel.

However, if neither parent was a diplomat, the nationality or immigration status of the parents does not matter.

* United States: The Citizenship Clause of the 14th Amendment to the United States Constitution, ratified in 1868, provides: "All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside." The concept of birthright citizenship applying to the child born of a foreign national in the country without proper credentials has never been formally litigated, but the U.S. Supreme Court's decision in ''United States v. Wong Kim Ark'' (1898) allowed the government to deny citizenship to U.S.-born children only in the cases of children born to foreign diplomats and children born to enemy forces engaged in hostile occupation of the country's territory, and, thus, this decision is most often interpreted as barring the government from denying citizenship to those born in the U.S. based on the alienage of their parents. (See United States nationality law.)

: On 20 January 2025, President Donald Trump, as part of Agenda 47, signed an executive order aiming to end the practice of birthright citizenship. The order mandates for at least one parent to be a U.S. citizen or lawful permanent resident for persons born in the U.S to become U.S. citizens at birth. The order was scheduled to come into effect on 19 February, but on 23 January, a federal judge in Seattle was the first to block its enforcement after referring it as unconstitutional. Four federal judges have blocked the order. Three federal appellate courts have upheld the judges blocks on the order. On 13 March, the administration asked the Supreme Court to intervene to allow the order to move forward by challenging three judges' injunctions. On 17 April, the Supreme Court decided to hear oral arguments on 15 May to determine whether the administration can enforce the order while legislation continues by considering whether the judges exceeded their authority when they issued their nationwide injunctions. Lawsuits from individuals, organizations, and twenty-two states suing to block the order as well are currently pending elsewhere.

, access date 2 October 2015 permits everyone born in Pakistan on or after that date to automatically receive Pakistani citizenship by birth except if they are the child of a foreign diplomat or enemy alien. On 11 November 2024 the National Assembly of Pakistan passed a bill to restrict citizenship for children born to foreigners. The bill would amend the Pakistan Citizenship Act of 1951 and would change the citizenship law by requiring every person born in Pakistan on or after 13 April 1951 to have at least one parent that is a citizen or a permanent resident of Pakistan in order to be granted Pakistani citizenship by birth or live in Pakistan for a period of 10 years from the date of their birth.

Restricted ''jus soli''

There is a trend in some countries toward restricting ''jus soli'' by requiring that at least one of the child's parents be a citizen, national or legal permanent resident of the state in question at time of the child's birth. Modification of ''jus soli'' has been criticized as contributing to economic inequality, the perpetuation of unfree labour from a helot underclass and statelessness. ''Jus soli'' has been restricted in the following countries:

Africa

* : According to the nationality law of the Arab Republic of Egypt and its latest amendments, children born to an Egyptian father or an Egyptian mother acquire citizenship at birth, regardless of their place of birth. Additionally, children born in Egypt to unknown parents (or found abandoned at a young age) are granted citizenship at birth.
* : A person who was born in Morocco to parents also born in Morocco and whose immigration is legal, can register as a Moroccan two years prior to becoming adult.
* : A person born in Namibia to a Namibian citizen parent or a foreign parent who is ordinarily resident in Namibia, is a Namibian citizen at birth (see Namibian nationality law).
* : A person born in São Tomé and Príncipe acquires São Toméan nationality, as long as the parents are residents of the country. The only exception is if any of the parents have diplomatic immunity (see São Toméan nationality law).
* : Since 6 October 1995, a person born in South Africa to South African citizens or permanent residents is automatically granted South African citizenship (see South African nationality law).
* : A person born before 1994 gains Sudanese nationality at birth if his father was also born in Sudan. If his father was not born in Sudan, they can apply to the Minister to be granted Sudanese nationality.
* : The Tanzania Citizenship Act of 1995, states that "any child born within the borders of the United Republic of Tanzania, on or after Union Day, 26 April 1964, is granted citizenship of Tanzania, except for children of a father who has diplomatic immunity, or parents who were enemy aliens and the territory was under enemy occupation." While Tanzania technically observes birthright citizenship, it is official practice that birth in Tanzania has to be further supported by descent from a Tanzanian parent to be recognized as a citizen by birth. This practice has gone uncontested in courts of law.
* : Individuals born in Tunisia are citizens by birth if their father and grandfather were born in Tunisia. Additionally, the person must declare before becoming an adult (20 years) that they want to be a citizen.

North America

* : The constitution was amended on 26 January 2010. The amendment broadened the definition of the 2004 migration law – which excluded from citizenship children born to individuals that were "in transit" – to include "non-residents" (including individuals with expired residency visas and undocumented workers).

South America

* : Article 96 of the constitution grants Colombian nationality by birth provided that at least one of the parents is a Colombian national or a legal resident. By presidential decree, in August 2019 nationality was granted to children of Venezuelan migrants born in Colombia regardless of residential status of their parents.

Asia

* : Article 52 of the constitution of Azerbaijan mentions that a person born on the territory of Azerbaijan is a citizen of Azerbaijan. Although in practice that provision is not enforced and persons are only granted citizenship by right based on the other provision within the article that mentions a person whose one parent is a citizen of Azerbaijan is also a citizen of Azerbaijan.
* : Children born to a foreign father with valid residency permits who himself was born in Bahrain have right to citizenship.
* : In 1996, Cambodia changed the law to grant citizenship to children born to foreign parents if both parents were born in Cambodia and are living legally in Cambodia (under Article 4(2)(a) of the 1996 Nationality Law).
*: China has strict nationality laws that limit ''jus soli'' citizenship to children born to stateless parents who have settled in China.
* Hong Kong: Since the July 1997 transfer of sovereignty over Hong Kong, most political rights and eligibility for most benefits are conferred to permanent residents regardless of citizenship. Conversely, PRC citizens who are not permanent residents (such as residents of Mainland China and Macao) are not conferred these rights and privileges. The Basic Law provides that all citizens of the People's Republic of China (PRC) born in the territory are permanent residents of the territory and have the right of abode in Hong Kong. The 2001 case '' Director of Immigration v. Chong Fung Yuen'' clarified that the parents need not have right of abode and as a consequence many women from Mainland China began coming to Hong Kong to give birth. By 2008, the number of babies in the territory born to Mainland China mothers had grown to twenty-five times the number five years prior. Furthermore, persons of Chinese ethnicity (wholly or partly) with PRC nationality born in Hong Kong are PRC nationals with Hong Kong permanent residence, even if their parents are non-PRC citizens (e.g. overseas-born Chinese). Non-PRC citizens born to non-PRC citizen Hong Kong permanent resident parents in Hong Kong also receive permanent residence of Hong Kong at birth. Other persons must have "ordinarily resided" in Hong Kong for seven continuous years in order to gain permanent residence (Articles 24(2) and 24(5)).
* : Indonesian citizenship by birth includes those born anywhere whose parents are both Indonesian nationals, or any person born in Indonesia with at least one Indonesian citizen parent, or a child born in Indonesia to unknown parents, or those born out of wedlock. Citizenship can also be granted to a permanent resident who has lived in Indonesia for a given period of time through naturalization, as long as the parents are stateless, or unknown.
* : Article 976(4) of the Civil Code of Iran grants citizenship at birth to persons born in Iran of foreign parents if one or both of the parents were themselves born in Iran. Article 976(5) People born in Iran of a father of foreign nationality who have resided at least one more year in Iran immediately after reaching the full age of 18; in other cases their naturalization as Iranian subjects will be subject to the stipulations for Iranian naturalization laid down by the law. New legislation passed by the Iranian Parliament in 2012 grants permanent residency to children born to Iranian mothers and foreign fathers. See Iranian nationality law.
* : Children born in Israel who have never acquired another citizenship are eligible to apply for Israeli citizenship between their 18th and 21st birthday if they have lived in Israel for over 5 years (see Israeli citizenship law).
* : Children born in Japan to stateless or unknown parents are Japanese nationals at birth.
* Macau: Similar to Hong Kong, most political rights and eligibility for most benefits are conferred to permanent residents regardless of citizenship since the December 1999 transfer of sovereignty over Macau, according to the Basic Law of Macau. Becoming a Macau permanent resident has slightly different requirements depending on an individual's nationality. Acquisition by birth operates on a modified ''jus soli'' basis; individuals born in Macau to Chinese nationals or to Portuguese citizens domiciled there are automatically permanent residents, while those born to other foreign nationals must have at least one parent who possesses right of abode (see Right of abode in Macau). Article 1.
* : A person born in Malaysia on or after 16 September 1963 with at least one parent being a Malaysian citizen or is automatically a Malaysian citizen (see Malaysian nationality law).
* Mongolia: A person born in Mongolia to foreign parents with valid residency permits can apply for Mongolian nationality when they turn the age of 16. A child in Mongolian territory with unidentified parents can receive Mongolian citizenship (see Mongolian nationality law).
*: Singapore practices a restricted form of jus soli where only those born with at least one Singaporean parent will be granted citizenship, unless the father of the child is an enemy alien, a foreign diplomat or if the birth occurred in occupied territory. (See Singapore nationality law).

* : Any child born to parents with Taiwanese citizenship, even those living abroad, can acquire Taiwanese nationality at birth. Children born in Taiwan to stateless parents or have unknown parentage are considered Taiwanese nationals at birth (see Taiwanese nationality law).
* : Thailand operated a system of pure ''jus soli'' prior to 1972. Due to illegal immigration from Burma, the Nationality Act was amended by requiring both parents to legally reside and be domiciled in Thailand for at least five years for their child to be granted Thai citizenship at birth. Furthermore, someone who has Thai citizenship by sole virtue of ''jus soli'' may be stripped of Thai citizenship under various conditions (such as living abroad), which does not apply to people who have Thai citizenship by virtue of ''jus sanguinis''.

Europe

* : Children born in France (including overseas territories) to at least one parent who is either (i) a French national or (ii) born in France, are automatically granted French nationality at birth. Children born in France to foreign parents who do not fulfil either of these two conditions may acquire citizenship from age 13 subject to residence conditions (see French nationality law). A child born in France to foreign parents becomes a French citizen automatically upon turning 18, provided that they reside in France on their 18th birthday and have had their primary residence in France for a total (but not necessarily continuous) period of at least 5 years since the age of 11. Children born in France to two stateless parents receive French nationality automatically at birth.
* : Prior to 2000, Germany's nationality law was based entirely on ''jus sanguinis'', but now children born in Germany on or after 1 January 2000 to non-German parents acquire German citizenship at birth if at least one parent has a permanent residence permit and resided in Germany for at least five years prior to the child's birth.
* Greece: Apart from regulations in past and historic nationality laws of Greece granting nationality ''jus soli'', the Greek Nationality Code of 2004 states that "A person born in Greek territory acquires by birth the Greek nationality if not acquiring alien nationality or is of unknown nationality". Additionally, as from 2015's amendment of 2004 Code (Law 4332 of 2015, G.G. A/76/9 July 2015), a child born in Greece by foreign parents shall acquire the right of Greek nationality with a combination of primary school attendance and parents' legal residence in Greece (5 years, 10 if the child is born prior to 5 years of legal residence). One year after the implementation of the law (as from July 2016), 6,029 children had been granted Greek nationality, out of 27,720 submitted applications.
* : On 1 January 2005, the law was amended to require that at least one of the parents be an Irish citizen; a British citizen; a resident with a permanent right to reside in Ireland or in Northern Ireland; or a legal resident residing three of the last four years in the country (excluding students and asylum seekers) (see Irish nationality law). The amendment was prompted by the case of Man Chen, a Chinese woman living in mainland United Kingdom who traveled to Belfast (Northern Ireland, part of the UK) to give birth in order to benefit from the previous rule whereby anyone born on any part of the island of Ireland was automatically granted Irish citizenship. The Chinese parents used their daughter's Irish (and thereby European Union) citizenship to obtain permanent residence in the UK as parents of a dependent EU citizen. Ireland was the last country in Europe to abolish unrestricted ''jus soli''. (see Irish nationality law).
* : The law that regulates this right is n. 91 of 5 February 1992. Article 4 paragraph 2 grants this possibility to a person born in Italy, who has legally resided there without interruption until reaching the age of 18, and becomes a citizen if they declare that they wish to acquire Italian citizenship within one year from the aforementioned date. They can make use of this right by submitting a simple declaration of will to the Civil Status Office of their municipality of residence. It is important to know that the Municipality of belonging is required, according to article 33 of Law 98/2013, to inform foreign citizens, during the 6 months preceding the age of 18, of the possibility of applying for Italian citizenship by the age of 19. In the absence of such communication, the request can be made even after the age of 19. In the event that, despite having been born in Italy, one has not had continuous residence from birth, but has resided in Italy for at least three years, at the age of 18, the application can be presented at the Prefecture with all the necessary documentation. Furthermore, in application of art. 1 of the same law and which aims to prevent statelessness, in Italy the ''jus soli'' is applied in other cases: – by birth in Italy of unknown or stateless parents; – by birth on Italian territory of foreign parents unable to transmit their citizenship to the subject according to the law of the country of origin; – the child of unknown persons found in the territory of the Republic is considered a citizen by birth, if the possession of another citizenship is not proven.
* : A person born since 1 January 2020 in Latvia or to Latvian-resident parents defaults to Latvian citizenship, although the child can instead gain a different citizenship at birth if both parents agree on this; if either parent is a citizen of another country, the parents must submit documentation disclaiming any other birthright citizenship the child would otherwise be entitled to in order for the child to be recognized as a Latvian citizen by ''jus soli''.
* : A person born in Luxembourg is automatically a Luxembourg citizen if at least one of their parents was also born in Luxembourg. Additionally, a person born in Luxembourg to foreign, non-Luxembourg-born parents can become a Luxembourg citizen from the age of 12 if they have resided uninterrupted in Luxembourg for at least 5 years immediately prior to submitting the application, and if at least one of their parents lived in Luxembourg uninterrupted for at least 12 months immediately preceding their birth. Furthermore, a person born in Luxembourg to foreign, non-Luxembourg-born parents gains Luxembourg citizenship automatically upon reaching the age of 18, provided that they have lived uninterrupted in Luxembourg for the preceding 5 years and at least one of their parents lived uninterrupted in Luxembourg for at least 12 months immediately preceding their birth.
* : A person born in Malta on or after 1 August 1989 is automatically a Maltese citizen if at least one of their parents is Maltese or was born in Malta. Anyone born in Malta before 1 August 1989, regardless of their parents' circumstances, is automatically a Maltese citizen, as the country conferred unconditional ''jus soli'' until this date (see Maltese nationality law).
* : After 31 December 1984, the following conditions apply: "The child's mother has Dutch nationality at the time of birth, or the child's parents both have Dutch nationality at the time of birth, or the father of the child has Dutch nationality at the time of birth and is married/registered partner to the non-Dutch mother or acknowledged the child, or the child and the child's mother have their principal residence in the Kingdom of the Netherlands at the time of birth. One of the mother's parents also had her main residence in the Kingdom on the day the mother was born, or the child and the child's father have their principal residence in the Kingdom of the Netherlands at the time of birth. One of the father's parents also had his main residence in The Kingdom on the day the father was born."
* : A child born in Portuguese territory to parents who do not possess another nationality is a Portuguese citizen. Also, a person born to foreign parents who were not serving their respective states at the time of birth is a Portuguese citizen if the person declares that they want to be Portuguese and provided that one of the parents has resided in Portugal for at least one year at the time of birth.
* : A child born in Spain to foreign parents may acquire Spanish citizenship ''jus soli'' under certain conditions, for example, if either one of the parents was also born in Spain or if neither of the parents can transmit their nationality to the child (such as stateless parents).
* : A child born on the territory of Ukraine may acquire Ukrainian citizenship ''jus soli'', if they do not acquire foreign nationality by ''jus sanguinis'' from parents, or if their parents have been granted refugee or asylum status in Ukraine, or if the child is stateless or of unknown nationality (se
Ukrainian citizenship law, articles 6 and 7
.
* : Prior to 1 July 2006 unmarried British fathers did not automatically pass on their nationality to children born out of wedlock, even if those children were born in the United Kingdom. ''Jus soli'' citizenship was abolished by the British Nationality Act of 1981. Since 1 January 1983 until the 2006 changes, children born out of wedlock to foreign (non-British) women were not eligible for citizenship unless the mother was legally "settled" in the country. In 2015 the law was applied retroactively to children born prior to 2006. Under the current law, if neither parent is British or settled, then a child born in the UK can apply for British citizenship if they have spent the first ten years of their life in the UK (see British nationality law).

Oceania

* : Since 20 August 1986, a person born in Australia acquires Australian citizenship by birth only if at least one parent was an Australian citizen or permanent resident; or else after living the first ten years of their life in Australia, regardless of their parents' citizenship status (see Australian nationality law).
* : Since 1 January 2006, a person born in New Zealand acquires New Zealand citizenship by birth only if at least one parent was a New Zealand citizen or permanent resident (includes Australian citizens and Permanent Residents) (see New Zealand nationality law), or if to prevent being stateless.

* India: A person who was born in India from 26 January 1950 until 1 July 1987 is a citizen by birth, regardless of the parents' nationality. It was restricted in 1987 to people with at least one parent who was a citizen. As of today, a person born in India is a citizen only if at least one parent is a citizen, and the other parent is a citizen or a legal migrant. These measures were brought in largely in reaction to illegal migration from Bangladesh.
