single citizenship

Single citizenship is the doctrine, embodied in Part II (Articles 5 to 11) of the Constitution of India, under which the Indian polity confers a single, uniform citizenship of the Union upon every citizen, irrespective of the State in which they are born or reside. Unlike federations such as the United States or Switzerland—where a citizen holds both national citizenship and the citizenship of a constituent State—India, though federal in structure, deliberately rejected dual citizenship. The Constituent Assembly, on the advice of B. R. Ambedkar, adopted single citizenship to forge national unity and counteract the fissiparous tendencies of caste, region, language, and communalism that had marked the partition era. Article 5 fixed citizenship at the commencement of the Constitution; Articles 6 and 7 dealt with migrants from and to Pakistan; Article 11 empowered Parliament to legislate on acquisition and termination of citizenship, leading to the Citizenship Act, 1955.

The practical effect of single citizenship is that all citizens enjoy the same political and civil rights throughout the territory of India, with no discrimination based on State of origin—subject to limited exceptions. Article 15 bars discrimination on grounds of place of birth, Article 16(1) guarantees equality of opportunity in public employment, and Article 19 secures the freedoms of movement, residence, and to carry on trade across the whole country. The exceptions are narrow and constitutionally sanctioned: Article 16(3) permits Parliament to prescribe residence as a qualification for certain State employment (operationalised through the Public Employment (Requirement as to Residence) Act, 1957); Articles 15(4), 16(4) and 16(4A) allow reservations; and the special provisions for States such as those under Article 371 and the erstwhile Article 35A (read with Article 370, abrogated in 2019) created limited domicile-based privileges in Jammu and Kashmir.

A defining feature is that India does not, as a rule, permit dual citizenship—a person acquiring foreign citizenship automatically loses Indian citizenship under Section 9 of the 1955 Act. The Overseas Citizen of India (OCI) scheme, introduced by the Citizenship (Amendment) Act, 2005, is frequently misread as dual citizenship; it is in fact a long-term visa and registration status conferring no political rights such as voting, contesting elections, or holding constitutional office. Persons of Indian Origin (PIO) cards were merged into the OCI category in 2015. The Citizenship (Amendment) Act, 2019 (CAA) altered the eligibility for naturalisation of certain persecuted minorities but did not disturb the single-citizenship principle itself.

For the UPSC Civil Services Examination, single citizenship is a staple of General Studies Paper II (Indian Polity and Governance) and of the Preliminary test. Examiners test the contrast between Indian and American federalism, the linkage between single citizenship and national integration, and the exceptions of domicile-based reservation and Article 16(3). Mains questions often ask candidates to evaluate whether single citizenship strengthens unity or whether residence-based exceptions dilute it, and to distinguish OCI status from genuine dual nationality.
