issued a royal proclamation to the "Princes, Chiefs and People of India" in 1858, declaring the Crown to be "bound to the natives of our Indian territories by the same obligations of duty which bind us to all our other subjects". Official rhetoric emphasised British subject status as a platform of equity, illustrating an imperial philosophy that all subjects of the Crown were equal before the law, regardless of race or background. This ideal was directly contradicted by a series of immigration restrictions in other colonies and Dominions that were created to exclude non-white migrants, including Indian British subjects, from entering their borders.

Post-independence policies


Partition and transition

British India was partitioned into two independent

was defined in this Act to have the same meaning. British subject/Commonwealth citizen status co-existed with the citizenship of each Commonwealth country. Because India had not enacted citizenship regulations by the time the 1948 Act took effect, Indians (and citizens of all other Dominions without citizenship laws) were provisionally classed as "British subjects without citizenship".

limited the scope of the Constitution's citizenship provisions for the immediate purpose of determining citizenship of these migrants. The Citizenship Act later enacted by Parliament in 1955 provides a full framework detailing citizenship requirements after that point. Any individual domiciled in India automatically became an Indian citizen in 1949 if they were: born in India, born to at least one parent who themself was born in India, or living in India for at least five years prior to the Constitution's commencement. Individuals of Indian descent living outside of the country could register for citizenship, but a person who had voluntarily acquired citizenship of a foreign state was barred from Indian citizenship. Commonwealth countries were defined as non-foreign in Indian law. Persons who migrated from the area that became part of Pakistan could be registered as Indian citizens if they (or a parent or grandparent) were born in any part of pre-partition India as defined in the

and had either become domiciled in Indian territory before 19 July 1948, or had been registered as a citizen of India by Dominion officials after that date, but before commencement of the Constitution. Migrants from Pakistan were required to have been domiciled in India for at least six months prior to applying for registration. Conversely, persons who migrated from India to Pakistan and settled there at any time are not considered Indian citizens.


Commonwealth citizenship

Under the 1955 Act, citizens of other Commonwealth member states were eligible to obtain Indian citizenship by registration in lieu of naturalisation, though there were no specific advantages to this method of acquisition. This pathway was available until Commonwealth citizen status was removed from Indian law in 2003. The UK itself updated its nationality law to reflect the more modest boundaries of its remaining territory and overseas possessions with the
British Nationality Act 1981 The British Nationality Act 1981 (c.61) is an Act of the Parliament of the United Kingdom concerning British nationality since 1 January 1983. History In the mid-1970s the British Government decided to update the nationality code, which had b ...

Accession of Sikkim

The
Kingdom of Sikkim The Kingdom of Sikkim (Classical Tibetan and sip, འབྲས་ལྗོངས།, ''Drenjong''), officially Dremoshong (Classical Tibetan and sip, འབྲས་མོ་གཤོངས།) until the 1800s, was a hereditary monar ...
was an autonomous monarchy in northeastern India from the 17th century to 1975. Although Britain (and later India) had control over its foreign affairs, Sikkim was never considered a princely state and always held full autonomy over domestic matters. Sikkim lacked codified nationality legislation until 1961, when the Sikkim Subject Regulation came into force. This legislation initially defined Sikkim subjects as anyone of native ancestry with their permanent home in the country, or a person permanently settled in Sikkim who had cut all ties with their previous country or had acquired
immovable property In English common law, real property, real estate, immovable property or, solely in the US and Canada, realty, is land which is the property of some person and all structures (also called improvements or fixtures) integrated with or affixe ...
in Sikkim. Subject status was further restricted by a requirement to have held property rights in Sikkim before 1937, effectively barring a large number of Nepali residents from obtaining a permanent status in the country. Dual citizenship was prohibited and women automatically lost their rights as subjects on their marriage to non-Sikkimese men. The ethnic qualification to subject status was particularly unpopular, leading to a revolt and the repeal of the regulation in the following year. However, the 1962 amendment also created a facilitated naturalisation pathway for non-subjects of native ancestry; any person descended from a person domiciled in Sikkim before 1850 could apply for subject status even if they did not live in the country. After the dissolution of Sikkim's monarchy and its accession to India in 1975, any person registered as a Sikkimese subject before 26 April 1975 became an Indian citizen. This process of acquisition left certain groups of people living in Sikkim stateless including long-term residents without property, Sikkimese women who married non-Sikkimese, and individuals who had otherwise qualified for subject status but failed to complete registration before 1975.


Legislative responses to migration

Successive governments since the 1980s have gradually increased the difficulty of acquiring Indian citizenship in response to changing patterns of immigration from neighbouring countries.

are not counted as illegal migrants for nationality purposes and are eligible for a reduced six-year residence requirement for naturalisation. The enactment of these changes sparked widespread protests for countering the secular nature of earlier citizenship law. The National Register of Citizens for Assam was comprehensively updated in 2019, with every citizen in the state required to show proof of their citizenship and pre-1971 settlement. 1.9 million people failed to provide sufficient documentation and were not listed on the register, leaving them stateless and subject to deportation.


Acquisition and loss of citizenship


Entitlement by birth or descent

All persons born in India between 26 January 1950 and 1 July 1987 automatically received citizenship by birth regardless of the nationalities of their parents. From 1 July 1987 until 3 December 2004, children born in the country received Indian citizenship by birth if at least one parent was a citizen. Since then, citizenship by birth is granted only if both parents are Indian citizens, or if one parent is a citizen and the other is not considered an illegal migrant. Children born overseas are eligible to become Indian citizens by descent if at least one parent is a citizen. The birth of eligible persons must be registered at an Indian diplomatic mission within a certain time frame for citizenship to be granted. Individuals born before 3 September 2004 were not required to have had their birth registered and received citizenship by descent automatically, unless either parent was an Indian citizen by descent, in which case registration of their birth was mandatory. Prior to 10 December 1992, only children of Indian fathers (not mothers) were eligible for citizenship by descent. Indian citizens by descent who hold another nationality automatically cease to be Indian citizens six months after reaching the age of 18, unless they renounce their foreign nationality.


Voluntary acquisition

Certain non-citizens qualify for citizenship by registration if they are married to an Indian citizen, are minor children of Indian citizens, or are of Indian origin and living either in the country or outside the area of pre-partition India. Persons whose parents are Indian citizens, who themselves or their parents had previously held Indian citizenship, or have held overseas citizenship for at least five years are also eligible to acquire citizenship by registration. Eligible individuals must be resident in the country for at least 12 months prior to an application for registration, and are subject to additional residence requirements depending on the criterion they qualified under. All other foreigners may become Indian citizens by

after residing in the country for at least 11 of the previous 14 years, with an additional 12 months of residence immediately preceding an application, a total of 12 years. Anyone acquiring Indian citizenship through either naturalisation or registration must renounce their previous nationalities. Between 2010 and 2019, about 21,000 people naturalised as Indian citizens. Any person deemed to be an illegal migrant is typically barred from obtaining citizenship through both naturalisation and registration. However, migrants from Afghanistan, Bangladesh, or Pakistan who belong to selected religious communities (Hindus, Sikhs, Buddhists, Jains, Parsis, or Christians) and arrived in India prior to 2015 are not considered illegal migrants. They are eligible for naturalisation with a reduced residence requirement; at least five years of residence during the previous 14-year period, along with the additional 12 months of residence immediately preceding an application.


Relinquishment and deprivation

Indian citizenship can be voluntarily relinquished by any person over the age of 18. Minor children of a person who gave up citizenship also cease to be citizens. On reaching adult age, these children have the option of resuming Indian citizenship within one year. Before 2003, relinquishment required holding nationality of another country, and all married women were considered to be of full age for the purposes of giving up citizenship regardless of their actual age. Minor children lost citizenship only if their fathers (not mothers) relinquished that status until 1992. Any Indian citizen who permanently settles in Pakistan or Bangladesh, or who voluntarily acquires citizenship of another country at any time automatically loses Indian citizenship. Between 2015 and 2019, about 670,000 people lost their Indian citizenship either through renunciation or automatic loss after acquiring a foreign nationality.


Overseas citizenship

Former Indian citizens and descendants of citizens have been eligible for overseas citizenship since its creation in 2003. This status gives its holders a lifelong entitlement to live and work in the country but they cannot vote in elections, stand for public office, and are subject to restrictions on entry into protected and restricted areas. Overseas citizenship is a status created specifically to work around the constitutional prohibition on holding multiple nationalities; it is not considered a full form of Indian citizenship. All persons who (or whose parents or grandparents) have ever been citizens of Pakistan or Bangladesh are permanently ineligible for overseas citizenship.
