Citizenship: Articles 5 to 11 and the Citizenship Act, 1955

Only one real past-year Prelims question maps to this exact chapter, 2021, a statement-based question on single citizenship, presidential eligibility, and whether citizenship can ever be terminated, a fair sample of how this chapter is tested: short, precise statements, at least one built around a fact most aspirants think they know and get slightly wrong. It is also a compact chapter to master completely. Part II of the Constitution, titled simply "Citizenship," runs from Article 5 to Article 11, seven articles in total, one of the shortest Parts in the document (Part III, Fundamental Rights, runs to dozens). The Federal System and Salient Features notes on this site each mention single citizenship in passing, as one unitary feature among several; neither explains how or why India ended up with it, or the statutory machinery that actually runs citizenship today. That is this chapter's job.

Part II is a snapshot of one date, not an ongoing law

The single most important thing to internalise about Articles 5 to 11 is what they actually do. They do not create a permanent framework for who becomes an Indian citizen; they settle exactly one question, who counted as a citizen of India at the commencement of the Constitution, 26 January 1950. Every one of Articles 5 to 9 is phrased around that single moment, "at the commencement of this Constitution," and Articles 10 and 11 exist specifically to hand off everything after that moment to Parliament. Once that handoff happens, Part II's job is done; the ongoing law, how citizenship is acquired after 1950, how it is lost, what happens to a child born in 2010, is entirely a creature of the Citizenship Act, 1955, not the Constitution's text. A Prelims trap worth watching for: a statement that describes a citizenship rule correctly but attributes it to "the Constitution" when it is in fact a Citizenship Act provision.

Article 5: citizenship by domicile at commencement

Article 5 is the default, largest category. At commencement, every person who has his domicile in the territory of India and (a) who was born in the territory of India, or (b) either of whose parents was born in the territory of India, or (c) who has been ordinarily resident in the territory of India for not less than five years immediately preceding such commencement, shall be a citizen of India. Domicile plus any one of these three conditions was enough, and this article made the overwhelming majority of the population citizens on 26 January 1950 without any application process at all.

Article 6: migrants from Pakistan around Partition

Article 6 overrides Article 5 to deal with people who migrated to India from the territory that became Pakistan. It requires, first, that the person, a parent, or any grandparent was born in undivided India as defined under the Government of India Act, 1935, and second, a test that turns on one cutoff, 19 July 1948:

• Migrated before 19 July 1948: citizen simply by having been ordinarily resident in India since the date of migration, no formal registration required.
• Migrated on or after 19 July 1948: needed registration as a citizen by an officer appointed by the Government of the Dominion of India, on an application made before the Constitution's commencement, and only after at least six months' prior residence in India.

That pre/post-19-July-1948 split, and which side needed registration, is precisely the kind of detail UPSC tests by swapping the date.

Article 7: the reverse case, migrants to Pakistan who returned

Article 7 is the harsher, mirror-image provision: a person who migrated from India to Pakistan after 1 March 1947 is not deemed a citizen of India, as a default rule. The one narrow escape is the resettlement proviso: a person who later returned under a permit for resettlement or permanent return is treated, for Article 6(b) purposes, as having migrated to India only after 19 July 1948, so they still had to go through registration, not automatic citizenship. Article 7's default bar is the provision most often mistested as absolute; the exception only opens the registration door, it does not itself grant citizenship.

Article 8: persons of Indian origin residing outside undivided India

Article 8 covers a person (or their parent or grandparent) born in undivided India who was ordinarily residing outside India. Such a person is deemed a citizen of India if registered by an Indian diplomatic or consular representative in the country where they resided, on an application made before or after commencement. This is the route for diaspora already settled abroad at Independence, distinct from the intra-subcontinent migration Articles 6 and 7 handle.

Article 9: voluntary foreign citizenship bars citizenship

Article 9 is short and absolute: no person shall be a citizen of India under Article 5, or deemed a citizen under Article 6 or 8, if that person has voluntarily acquired the citizenship of a foreign state. This is the constitutional root of the principle, still alive in the Citizenship Act today, that voluntarily taking up another country's citizenship is incompatible with holding Indian citizenship. Only Articles 5, 6 and 8 are named because those are the three that could otherwise make someone a citizen at commencement; Article 7 needs no such override since it already excludes Pakistan migrants by default.

Article 10: continuance subject to Parliament's law

Article 10 says every person who is or is deemed a citizen "under any of the foregoing provisions of this Part" continues to be a citizen, but explicitly "subject to the provisions of any law that may be made by Parliament." That subordinate clause does all the work: citizenship as fixed by Articles 5 to 9 is not permanently locked in; it can be reshaped by an ordinary law of Parliament.

Article 11: the pivot, Parliament's plenary power over citizenship

Article 11 is the most consequential of the seven, precisely because of how little it says: nothing in the foregoing provisions of this Part shall derogate from the power of Parliament to make any provision with respect to the acquisition and termination of citizenship, and all other matters relating to citizenship. Articles 5 to 10 answer a closed, historical question; Article 11 hands everything after that date to Parliament. This is why citizenship, alone among major constitutional subjects, can be amended by an ordinary law, by simple majority, without going near Article 368's amendment machinery: the substantive rules were never constitutionally entrenched. Parliament exercised exactly this power to enact the Citizenship Act, 1955, the statute that governs the rest of this note.

The Citizenship Act, 1955: the actual ongoing framework

The Citizenship Act, 1955 (Act No. 57 of 1955) sets out five distinct modes of acquiring Indian citizenship after commencement: birth, descent, registration, naturalisation, and incorporation of territory. It has been amended repeatedly, most consequentially in 1986, 2003 (in force only from 2004), 2005, 2015 and 2019, and the birth-citizenship rule in particular has been progressively tightened across these amendments, one of the most reliably tested sequences in this chapter.

Citizenship by birth: a three-tier, tightened rule

Section 3 applies three different rules depending on when the birth occurred:

• 26 January 1950 to before 1 July 1987: unconditional. Anyone born on Indian soil in this window is a citizen by birth regardless of either parent's nationality, the original jus soli position the 1955 Act started with.
• 1 July 1987 to before 3 December 2004: at least one parent had to be an Indian citizen at the time of birth. The 1 July 1987 cutoff traces to the Citizenship (Amendment) Act, 1986, which first introduced this condition. This intermediate tier is genuinely distinct from both neighbours, not a direct jump from unconditional to the current rule.
• On or after 3 December 2004 (the commencement of the Citizenship (Amendment) Act, 2003, formally Act 6 of 2004): either both parents must be Indian citizens, or one parent a citizen and the other not an "illegal migrant" at the time of birth. This is meaningfully stricter than the 1987-2004 tier, where one Indian parent sufficed regardless of the other parent's status.

The naming is itself a trap: the amending Act's short title is "Citizenship (Amendment) Act, 2003," but its commencement, the date the new rule actually took effect, was 3 December 2004. The safer anchor is the specific date, not either year label alone. Two further exclusions under Section 3(2): no birth citizenship if a parent held diplomatic immunity as a foreign envoy's family and was not themselves Indian, or if a parent was an "enemy alien" and birth occurred in enemy-occupied territory.

Descent, registration, naturalisation, incorporation of territory

• Descent (Section 4): a person born outside India is a citizen by descent if the father was an Indian citizen at the time of birth (before 10 December 1992), or if either parent was (on or after that date, a gender-neutrality correction in its own right). Registration of the birth at an Indian consulate within a year (or later, with permission) is required, plus, for births after 3 December 2004, a parental declaration that the child holds no other country's passport.
• Registration (Section 5): available without naturalisation's stiffer residence test to defined categories, chiefly a person of Indian origin ordinarily resident in India for seven years before applying, a person married to an Indian citizen similarly resident for seven years, minor children of Indian citizens, and a person who has held OCI status for five years plus twelve months' subsequent residence, the formal bridge from OCI to full citizenship covered below.
• Naturalisation (Section 6): the general route for a foreign national not otherwise covered, requiring the qualifications in the Act's Third Schedule (broadly, twelve years' cumulative Indian residence, including the twelve months immediately before applying). The Central Government can waive these for a person of distinguished service to science, philosophy, art, literature, world peace, or human progress generally.
• Incorporation of territory (Section 7): when territory becomes part of India (as with Goa, Daman and Diu, Puducherry, and Sikkim after 1955), the Central Government can, by notified order, specify who becomes a citizen by virtue of their connection to it.

Loss of citizenship: renunciation, termination, deprivation

Three distinct routes exist, and the claim that citizenship, once acquired, can never be lost, exactly the 2021 PYQ's third statement, is false:

• Renunciation (Section 8): a citizen of full age and capacity can voluntarily declare renunciation; once registered, that person ceases to be a citizen, and any minor child does too (with a right to reclaim citizenship within a year of attaining full age).
• Termination (Section 9): automatic, not discretionary. Any citizen who, by naturalisation, registration, or otherwise, voluntarily acquires another country's citizenship ceases to be an Indian citizen from that moment. This is Article 9's 1950 principle, extended by statute as a permanent, ongoing rule.
• Deprivation (Section 10): the one route that is a government decision, against a citizen by naturalisation, registration, or narrow Article 5(c)/6(b)(ii) categories, on grounds including fraud, disloyalty shown by act or speech, unlawful wartime trading with an enemy, a sentence of at least two years within five years of registration or naturalisation, or seven continuous years abroad without registering an intention to retain citizenship. Natural-born citizens under Article 5(a) or (b) cannot be deprived under this section at all.

Single citizenship: why, and how it is enforced

India runs one uniform "citizen of India" status regardless of which state a person is born in, lives in, or moves to, unlike the American federal model, where a person holds both national and, by residence, state citizenship. What the Federal System and Salient Features notes flag only as a feature, this note can explain mechanically: Articles 5 to 8 set one set of criteria for the whole territory at commencement, with no article in Part II contemplating a state-specific category, and Article 11 handed the entire ongoing subject to a single central Parliament, not to state legislatures. Because citizenship is a Union subject administered by one uniform statute, no state can create its own citizenship category or condition a citizen's Article 19 rights, to move, reside, or work anywhere in India, on which state they came from, the direct legal payoff of routing citizenship exclusively through Union-level text rather than splitting it, as the American model does, between national and state citizenship.

Overseas Citizenship of India (OCI): not dual citizenship

OCI is the status most often wrongly conflated with "dual citizenship," and getting the distinction right is a real, recurring exam angle. Neither the Constitution nor the Act permits an Indian citizen to simultaneously hold a foreign citizenship; Section 9 makes voluntary foreign citizenship acquisition an automatic termination, with no exception. OCI was created precisely because full dual citizenship was never on the table.

OCI (Section 7A) was first inserted by the Citizenship (Amendment) Act, 2003, limited to a specified list of countries, then broadened by the Citizenship (Amendment) Act, 2005, to persons of Indian origin from any country (other than Pakistan and Bangladesh) whose own law permits some form of dual citizenship; the Ministry of Home Affairs dates the scheme as operational from 2 December 2005. Sections 7A to 7D were restructured again by the Citizenship (Amendment) Act, 2015, folding the older "Person of Indian Origin" card into OCI, and amended further in 2019.

An OCI cardholder is, in the Ministry of Home Affairs' own words, "a foreign national holding passport of a foreign country" and "is not a citizen of India." Section 7B confers a defined bundle by notification: chiefly a multiple-entry lifelong visa for any purpose, exemption from foreigner registration regardless of stay length, and parity with Indian nationals or NRIs on specific matters (domestic air fares, monument entry fees, some professional practice rights, certain entrance exams, and property purchase other than agricultural land, farmhouses or plantation property). Section 7B(2) then draws an exhaustive line around what OCI does not confer: no Article 16 public-employment equality, no eligibility for President, Vice-President, or judge of the Supreme Court or High Court, no voting rights, and no eligibility for the Lok Sabha, Rajya Sabha, or any state legislature. This is the exam trap the 2021 PYQ's second statement tests from another angle: full citizens, not OCI cardholders, are eligible for constitutional office, and even among full citizens the President need not be a citizen "by birth only."

The route from OCI to full citizenship is deliberate and gated, not automatic: Section 5(1)(g) lets a person who has held OCI status for five years, and been ordinarily resident in India for twelve months before applying, apply for citizenship by registration. Holding an OCI card alone, without that separate residence-and-application test, never converts to citizenship by itself.

Quick revision points

• Part II (Articles 5 to 11) is one of the shortest Parts in the Constitution and governs citizenship only at commencement, 26 January 1950, not on an ongoing basis; everything after runs on the Citizenship Act, 1955, under authority Article 11 hands to Parliament.
• Article 5: citizenship by domicile at commencement, for a person born in India, or with a parent born in India, or resident five years before commencement.
• Article 6: migrants from Pakistan; key date 19 July 1948, before which residence sufficed, on or after which registration (plus six months' prior residence) was required.
• Article 7: migrants to Pakistan after 1 March 1947 are generally not citizens; a resettlement permit is a narrow exception that opens registration, not automatic citizenship.
• Article 8: Indian-origin persons outside undivided India, via registration with an Indian diplomatic or consular representative.
• Article 9: voluntarily acquiring foreign citizenship bars citizenship under Articles 5, 6 or 8, the root of Section 9 of the 1955 Act.
• Articles 10 and 11: continuance is "subject to" parliamentary law; Article 11 gives Parliament plenary power over acquisition, termination and all other citizenship matters, the pivot from constitutional to statutory law.
• The Citizenship Act, 1955 provides five modes: birth, descent, registration, naturalisation, incorporation of territory.
• Birth citizenship (Section 3) tightened in three stages: unconditional 26 January 1950 to before 1 July 1987 (Act of 1986 set this cutoff); one Indian parent required 1 July 1987 to 3 December 2004; from 3 December 2004 (Act of 2003, commenced 2004), both parents Indian citizens, or one Indian citizen parent and the other not an illegal migrant.
• Citizenship is lost three ways: renunciation (voluntary), termination (automatic, on acquiring foreign citizenship), deprivation (government order, on fraud, disloyalty, or prolonged unregistered residence abroad; only naturalised or registered citizens, never natural-born ones under Article 5(a)/(b)).
• Single citizenship: one uniform status administered entirely at the Union level, no state-level citizenship category anywhere in the Constitution or Act, unlike the American dual national-state model.
• OCI is not dual citizenship. A cardholder remains a foreign national; OCI confers a lifelong visa and specified rights (Section 7B(1)) but expressly excludes voting, constitutional offices, and most public employment (Section 7B(2)). Five years' OCI plus twelve months' residence opens registration under Section 5(1)(g), but OCI alone never converts automatically.

The chapter rewards precision on exactly these points, in order: which article or section governs a rule, which specific date a tightening took effect, and the sharp line between what OCI grants and what only full citizenship grants. A statement-based question here is rarely testing whether the reader has heard of single citizenship; it is testing whether the reader can place each rule in the right article, the right section, and the right year.
