Indian Citizenship (Articles 5–11): Acquisition, Loss, CAA & OCI
Articles 5–11 of the Constitution frame citizenship at commencement, while the Citizenship Act, 1955 governs its acquisition, determination and termination thereafter. This complete guide covers the constitutional provisions, the 5 ways to acquire and 3 ways to lose citizenship, single citizenship, NRC, OCI/NRI/PIO, and the CAA 2019 — updated with the latest 2025–26 changes.
Citizenship is the legal status of a person recognised as a full member of a sovereign state, carrying specific rights and duties. The Indian Constitution establishes a single citizenship for the whole country. Although it does not formally define citizenship, Articles 5–11 (Part II) identify who became citizens when the Constitution commenced, and the Citizenship Act, 1955 governs everything after that.
Single Citizenship: The Core Idea
Unlike the USA, which has dual citizenship (national + state), India — despite being federal — provides only single, uniform national citizenship. There is no separate "state citizenship," and every citizen owes allegiance to, and enjoys equal rights across, the whole of India.
The population splits into citizens (full civil & political rights) and aliens (citizens of another state). Aliens are either friendly aliens (from countries with cordial ties) or enemy aliens (from a country at war with India, who enjoy fewer protections).
Rights Available Only to Citizens
Some rights are reserved exclusively for Indian citizens (aliens don't get them):
- Article 15 — no discrimination on religion, race, caste, sex or place of birth.
- Article 16 — equal opportunity in public employment.
- Article 19 — the six freedoms (speech, assembly, association, movement, residence, profession).
- Articles 29 & 30 — cultural and educational rights.
- Right to vote, contest elections, and hold offices like President, Vice-President, etc.
Constitutional Provisions: Articles 5–11
The Constitution only identifies citizens at commencement (26 January 1950) and leaves the rest to Parliament:
| Article | Provision |
|---|---|
| Article 5 | Citizenship at the commencement of the Constitution (by birth, parentage, or 5 years' ordinary residence). |
| Article 6 | Rights of citizenship of certain persons who migrated from Pakistan to India. |
| Article 7 | Rights of citizenship of certain migrants to Pakistan (who later returned). |
| Article 8 | Rights of citizenship of certain persons of Indian origin residing abroad. |
| Article 9 | Persons voluntarily acquiring foreign citizenship shall not be citizens. |
| Article 10 | Continuance of the rights of citizenship. |
| Article 11 | Empowers Parliament to regulate citizenship by law. |
Using the Article 11 power, Parliament enacted the Citizenship Act, 1955 — amended several times (1986, 1992, 2003, 2005, 2015, 2019).
Acquisition of Citizenship (5 Ways)
Under the Citizenship Act, 1955 and Citizenship Rules, 2009, citizenship can be acquired in five ways:
The Citizenship (Amendment) Act, 1985 set special cut-offs for Assam: those who came before 1 January 1966 are deemed citizens; those between 1 Jan 1966 and 25 March 1971 must register.
Loss of Citizenship (3 Ways)
The Act provides three modes of losing citizenship:
- Renunciation — a voluntary declaration by a citizen (a minor may resume citizenship within one year of turning 18). Over 16 lakh Indians have renounced citizenship since 2011, including about 2.25 lakh in 2023.
- Termination — automatic, when a citizen voluntarily acquires another country's citizenship (not applicable during a war).
- Deprivation — a compulsory termination by the Centre (for citizens by naturalisation/registration) for fraud, disloyalty to the Constitution, trading with the enemy in wartime, etc.
OCI, NRI & PIO — Know the Difference
| Category | Who | Key Point |
|---|---|---|
| OCI | Person of Indian origin (and spouse) given permanent residency | Live/work in India, own property (not agricultural), visa-free entry — but NOT dual citizenship; cannot vote or hold public office. |
| NRI | Indian citizen residing abroad for work/business | Still an Indian citizen — retains passport & voting rights. |
| PIO | Person whose ancestors were Indian, now holding a foreign passport | A foreign national; the PIO card scheme was merged into OCI in 2015. |
NRC (National Register of Citizens)
The NRC is a register of Indian citizens, first prepared in 1951 from the Census. At present, only Assam has an updated NRC, aimed at identifying foreign nationals in the state bordering Bangladesh.
Citizenship (Amendment) Act, 2019 (CAA) — Latest Status
The CAA 2019 amended the 1955 Act to offer an accelerated path to citizenship for Hindu, Sikh, Buddhist, Jain, Parsi and Christian migrants from Afghanistan, Bangladesh and Pakistan, reducing the naturalisation residence requirement from 11 years to 5. It is now operational — not merely proposed:
Supporters call the CAA humanitarian — a refuge for persecuted minorities from theocratic neighbours, consistent with India's civilisational ethos. Critics argue it violates Article 14 by using religion as a criterion, excludes groups like Sri Lankan Tamils, Rohingya and Ahmadiyya/Shia Muslims, and — linked with a nationwide NRC — could risk disenfranchisement. The matter is under challenge before the Supreme Court. (Present both sides in Mains.)
Citizenship — UPSC PYQ
Q (Prelims 2021): (1) There is only one citizenship and one domicile. (2) A citizen by birth only can become the Head of State. (3) A foreigner once granted citizenship cannot be deprived of it under any circumstances. Which are correct? Answer: (a) 1 only. (India has single citizenship & domicile — correct. The President need only be a citizen, not "by birth" — so 2 is wrong. Deprivation of citizenship is possible — so 3 is wrong.)
