Citizenship in India: Articles 5 to 11 and the CAA story

Citizenship decides who belongs to the Republic and who does not, and in India the answer comes from two places: a short Part of the Constitution written for Partition, and a 1955 law that has been amended six times, most controversially in 2019. This article explains Articles 5 to 11, the five ways to become a citizen, the three ways to lose it, and the full story of the Citizenship Amendment Act and the NRC.

Articles 5 to 11: citizenship for a Partitioned country

Part II is only seven articles long because it had one urgent job: deciding who was a citizen on 26 January 1950, in the aftermath of Partition. Article 5 gave citizenship to everyone domiciled in India who was born in India, or had either parent born in India, or had lived in India for five years. Article 6 dealt with migrants from Pakistan, distinguishing those who came before 19 July 1948 from those who came after. Article 7 took citizenship away from those who migrated to Pakistan, with a provision for returnees. Article 8 covered persons of Indian origin abroad who registered with Indian missions.

Article 9 laid down the single-citizenship rule: voluntarily acquiring another country's citizenship ends Indian citizenship. Article 10 promised that citizenship, once held, would continue subject to parliamentary law. And Article 11, the most important of the seven for the exam, gave Parliament full power to make law on acquisition and termination of citizenship, which it exercised through the Citizenship Act of 1955.

Single citizenship: one passport for the whole country

Despite the federal structure, India chose single citizenship. There is no citizenship of Maharashtra or Tamil Nadu as there is citizenship of California or Texas. The framers did this consciously to knit the country together after Partition. A single citizenship means one set of political rights everywhere: voting, contesting elections and holding public office flow from the same source across the country.

The rule has one sharp edge that UPSC loves. Under Article 9, if an Indian voluntarily acquires the citizenship of another country, Indian citizenship ends automatically. There is no dual citizenship in India. The Overseas Citizen of India (OCI) card, often confused with dual citizenship, is only a lifelong visa with some economic rights, not citizenship, and confers no voting rights.

The five doors in: how citizenship is acquired

The Citizenship Act, 1955 lays down five ways to become an Indian citizen. Birth is the first: originally everyone born in India was a citizen, but amendments in 1986 and 2003 narrowed this. A person born between 26 January 1950 and 1 July 1987 is a citizen by birth alone; one born between 1 July 1987 and 3 December 2004 needs at least one citizen parent; and one born on or after 3 December 2004 needs both parents to be citizens, or one citizen parent with the other not being an illegal migrant. India thus moved from birth on the soil toward citizenship by descent.

Descent is the second door: a person born abroad to an Indian parent can be a citizen if the birth is registered at an Indian consulate within one year. Registration is the third: persons of Indian origin, spouses of citizens and minor children of citizens can apply after prescribed residence, generally seven years. Naturalisation is the fourth: a foreigner who meets the Third Schedule residence test, twelve months in India immediately before applying plus eleven of the preceding fourteen years, and who renounces any foreign citizenship, can be naturalised. Incorporation of territory is the fifth: when a new territory joins India, as Pondicherry did in 1962, the government notifies who becomes a citizen.

The three doors out: renunciation, termination, deprivation

Citizenship can be lost in three ways. Renunciation is voluntary: a citizen of full age can declare the wish to give up citizenship, though minor children who lose it this way can resume it at eighteen. Termination is automatic: acquiring another country's citizenship ends Indian citizenship by operation of law. Deprivation is compulsory and punitive: the government can strip citizenship obtained by fraud, for disloyalty to the Constitution, or for trading with an enemy during war, with procedural safeguards because statelessness is at stake.

The CAA story: what the 2019 amendment actually does

The Citizenship Amendment Act, passed in December 2019, creates a fast track for six religious minority communities, Hindus, Sikhs, Buddhists, Jains, Parsis and Christians, from Afghanistan, Bangladesh and Pakistan, who entered India on or before 31 December 2014. For this group, the naturalisation residence requirement drops from eleven years to five, and pending illegal-migration proceedings against them abate on grant of citizenship.

The government's justification rests on Partition's unfinished business: these communities face religious persecution in theocratic neighbours, and India is presented as their natural refuge, as with Parsis, Jews and Tibetans. Legally, the defence invokes Article 14's reasonable classification: a law may treat a defined group differently if the classification has a rational link to its purpose.

The criticism is equally structured. The law uses religion as a criterion for citizenship for the first time, which critics say violates the secular basic structure. It excludes persecuted Muslim sects like the Ahmadiyyas of Pakistan, and says nothing about refugees from neighbours like Sri Lankan Tamils or Rohingya from Myanmar. In Assam, the 31 December 2014 cut-off collides with the Assam Accord's 24 March 1971 cut-off, and a nationwide register would impose a documentation burden on the poorest citizens, as the Assam experience showed.

The NRC thread: from 1951 to Assam 2019

The National Register of Citizens is older than the controversy. The first NRC was prepared in Assam in 1951. The Assam Accord of 1985, which ended the anti-foreigner agitation, fixed 24 March 1971 as the cut-off for detecting illegal migrants. The 2003 amendment introduced the term illegal migrant and mandated a national NRC. Between 2013 and 2019, under Supreme Court monitoring, Assam updated its NRC in an enormous and expensive exercise; the August 2019 final list excluded 19.06 lakh people, unsettling every side of the debate.

In October 2024, a Constitution Bench in Assam Sanmilita Mahasangha v. Union of India upheld Section 6A of the Citizenship Act by 4:1, validating the special 1971 cut-off for Assam as a reasonable classification given the state's unique history. The Court separated the Assam question from the pending challenge to the CAA itself, which remains before the Supreme Court on the Article 14 and secularism arguments.

How the CAA rules work: the 2024 mechanism

The CAA lay dormant for four years because rules were not notified. In March 2024, the Home Ministry notified the Citizenship Amendment Rules, creating a fully digital process that bypasses state governments. Applicants apply through the Indian Citizenship Online portal with a self-declaration and relaxed documentation, a District-Level Committee headed by the Superintendent of Post verifies the papers and administers the oath, and an Empowered Committee led by the Director of Census Operations takes the final decision and issues digital certificates. Applicants must also show proficiency in a language listed in the Eighth Schedule.

By routing the process through central committees, the rules remove the discretion of state governments, several of which had announced they would not implement the CAA. The law also carries geographic carve-outs: it does not apply in the Sixth Schedule tribal areas of Assam, Meghalaya, Mizoram and Tripura, nor in the Inner Line Permit areas, a concession to the northeast's anxieties about demographic change. For Prelims, the key facts are the six communities, the three countries, the 31 December 2014 cut-off, the March 2024 rules, and these tribal-area exclusions.

Judicial landmarks on citizenship and migration

In Sarbananda Sonowal v. Union of India (2005), the Court struck down the Illegal Migrants (Determination by Tribunals) Act, calling large-scale illegal migration from Bangladesh an external aggression against Assam. In Assam Sanmilita Mahasangha (2024), it upheld Section 6A and the 1971 cut-off for Assam. Together these rulings show the Court treating illegal migration as a national security question while insisting that citizenship determination follow due process.

Key Terms

• The Citizenship Amendment Act, 2019: The Citizenship (Amendment) Act, 2019 amends the 1955 Act to fast-track Indian citizenship for Hindu, Sikh, Buddhist, Jain, Parsi and Christian migrants from Pakistan, Bangladesh and Afghanistan who entered India on or before 31 December 2014, cutting the residency requirement to five years. It excludes Muslims, triggering nationwide protests and a pending Article 14 challenge. the first citizenship certificates under the Act were issued in May 2024 after rules were notified in March 2024
• Overseas Citizen of India: An Overseas Citizen of India (OCI) is a foreign national of Indian origin registered under the Citizenship Act, 1955, who enjoys lifelong visa-free travel to India and parity with NRIs in economic and educational matters. OCI status is not dual citizenship: holders cannot vote, contest elections or hold constitutional posts. For UPSC, it is central to diaspora policy questions and the distinction between NRI, PIO and OCI. Introduced through the 2005 amendment to the Citizenship Act, 1955
• basic structure doctrine: Basic structure doctrine is the constitutional principle laid down in Kesavananda Bharati (1973) that Parliament may amend the Constitution under Article 368 but cannot destroy its basic structure. Features like supremacy of the Constitution, rule of law, judicial review, and federalism are beyond amendment. For UPSC mains, it is the central doctrine in any answer on the balance between Parliament's amending power and constitutional limits. Kesavananda Bharati v. State of Kerala, Supreme Court, 1973
• Citizenship Act, 1955: The Citizenship Act, 1955 is the law detailing how Indian citizenship is acquired and lost: by birth, descent, registration, naturalisation, and incorporation of territory, and how it can be renounced or terminated. Parliament has amended it repeatedly, in 1986, 2003, 2005, 2015, and most controversially in 2019. It operationalises the bare framework of Articles 5 to 11 of the Constitution. The 2003 amendment introduced the Overseas Citizen of India category.
• Union of India: The Union of India is the constitutional name of the Indian state, comprising the States and Union Territories in the First Schedule, as Article 1 declares that India, that is Bharat, shall be a Union of States. It is the legal personality that can sue and be sued under Article 300 and that can acquire territory. For UPSC, the term is the starting point of every GS-2 discussion of Indian federalism. Article 1 of the Constitution
• Election Commission: The Election Commission is the constitutional body under Article 324 that superintends, directs and controls elections to Parliament, state legislatures and the offices of President and Vice-President. It can function as a multi-member body and enjoys powers to ensure free and fair polls. For UPSC, its independence, powers and the model code of conduct are staple polity topics. T. N. Seshan's assertive tenure as Chief Election Commissioner (1990-96) strengthened the Commission's authority.
• Empowered Committee: An Empowered Committee is a high-level committee given real decision-making authority, usually comprising ministers or senior officials, to resolve complex Centre-state or inter-ministerial issues. The best-known example is the Empowered Committee of State Finance Ministers that designed the Goods and Services Tax framework. It matters for UPSC as a model of cooperative federalism in economic policymaking. Example: the Empowered Committee of State Finance Ministers steering GST design before the GST Council took over. the Empowered Committee of State Finance Ministers steering GST design before the GST Council took over
• Eighth Schedule: The Eighth Schedule lists the officially recognised languages of the Indian Constitution, currently 22, beginning with Assamese and ending with Urdu. Languages were added by the 21st Amendment (Sindhi, 1967), the 71st Amendment (1992) and the 92nd Amendment (2003). For UPSC, the schedule is tied to official-language policy under Articles 344(1) and 351. Bodo, Dogri, Maithili and Santhali were added to the schedule by the 92nd Amendment in 2003.
• electoral rolls: Electoral rolls are the official lists of voters registered for each constituency, maintained by the Election Commission of India. Registration follows the Representation of the People Act, 1950, with electoral registration officers handling enrolment, revision and publication of rolls. Only citizens aged 18 or above with ordinary residence in the constituency can be included. For UPSC, they matter for GS-2 questions on free and fair elections, voter rights and electoral reforms. The Special Summary Revision of electoral rolls is conducted annually, allowing new voters who turn 18 to enrol on the qualifying date of 1 January.
• Sixth Schedule: The Sixth Schedule is the part of the Constitution (Articles 244(2) and 275(1)) providing for the administration of tribal areas in Assam, Meghalaya, Tripura and Mizoram through Autonomous District Councils and Autonomous Regional Councils. These councils can legislate on land, forests, customs and village administration and receive grants from the Consolidated Fund of India. It matters for UPSC polity questions on tribal autonomy and governors' powers. The Bodoland Territorial Council, Assam
• Third Schedule: The Third Schedule of the Constitution prescribes the forms of oaths and affirmations for Union and state ministers, members of Parliament and state legislatures, judges of the Supreme Court and High Courts, and the Comptroller and Auditor General. Every oath affirms allegiance to the Constitution and a commitment to uphold the sovereignty and integrity of India. a newly elected MP must subscribe to the Third Schedule oath before taking a seat in the House
• Supreme Court: The Supreme Court of India is the apex court and final interpreter of the Constitution under Articles 124 to 147. It comprises the Chief Justice and 33 other judges, exercises original, appellate and advisory jurisdiction, and guards fundamental rights through writs under Article 32. Its doctrines of basic structure and judicial review shape Indian polity and federalism. Example: Kesavananda Bharati (1973) laying down the basic structure doctrine.

Practice questions

Citizens and aliens: who gets which rights

Citizens are full members of the Indian state who owe allegiance to it; aliens are citizens of other states. The distinction decides which fundamental rights a person can claim, and the exam tests the dividing line directly.

NRC vs NPR: the two registers examiners confuse

Two different registers, two different purposes, one confused acronym pair. The NRC counts citizens; the NPR counts residents.

NRI, PIO, OCI: three different relationships with India

India allows no dual citizenship, but it recognises three distinct categories of Indians abroad.

The Centre can cancel OCI registration for fraud, a sentence of two or more years within five years, national-security reasons, or legal violations, but only after giving the holder a chance to be heard.

Citizenship provisions at a glance

The concept of citizenship forms the foundation of a democratic nation. It defines the relationship between an individual and the state, outlining the rights, privileges, and duties that bind them. Part II and Articles 5 to 11 gave India its starting citizens; everything since has been built by Parliament under Article 11.

No dual citizenship, but an OCI middle path

India does not allow dual citizenship: any Indian who acquires foreign citizenship automatically loses Indian citizenship under Article 9. The policy rests on concerns over national security, political allegiance and administrative complexity, though critics argue it weakens diaspora ties. The middle path is the Overseas Citizen of India scheme, introduced by the Citizenship (Amendment) Act, 2005.

OCI benefits include a lifelong visa, exemption from police registration, and rights to study, work, own residential and commercial property, adopt and invest in India. Restrictions bar OCI holders from voting, holding government posts, contesting elections, owning agricultural land or holding an Indian passport. The 2021 guidelines require prior permission for missionary work, journalism, research and visits to restricted areas, and a later notification under Section 7D tightened cancellation: registration can be revoked on conviction and sentence of at least two years' imprisonment, or on a chargesheet for an offence punishable with seven years or more.

In the other direction, the 2023 re-issuance reform simplified life for the diaspora: OCI cardholders now re-issue the card only once after a new passport past age 20, and for passports issued before 20 or after 50 a fresh upload on the OCI portal suffices.
