Distinguish between citizenship and Overseas Citizenship of India (OCI). Can dual citizenship be recognised under the Indian Constitution?

Citizenship is full legal membership of the Indian State, governed by Articles 5–11 and the Citizenship Act, 1955. Overseas Citizenship of India, despite its name, is a special immigration and residency status for persons of Indian origin holding foreign passports — a facility, not membership.

Basis of distinction

• Legal source: Citizenship is acquired by birth, descent, registration, naturalisation or incorporation of territory under the Citizenship Act, 1955; an OCI card is issued under Section 7A of the same Act [2].
• Nationality: An OCI cardholder "is a foreign national holding passport of a foreign country and is not a citizen of India" [3].
• Political rights: Only citizens vote, contest elections, or become members of Parliament and State legislatures. OCI cardholders are barred from voting and from constitutional posts — President, Vice-President, Judge of the Supreme Court or High Court [3].
• Public employment: OCI cardholders cannot be appointed to public services and posts under the Union or States [3].
• Economic rights: OCI cardholders enjoy lifelong multiple-entry visa and parity with NRIs in most economic fields, but cannot acquire agricultural land, farmhouses or plantations [3].

Can dual citizenship be recognised?

• Article 9 bars it squarely: a person voluntarily acquiring the citizenship of a foreign State ceases to be an Indian citizen [1].
• Section 9(1), Citizenship Act, 1955, extends this bar beyond the commencement provisions to all citizens, with automatic termination on voluntary acquisition [2].
• Disputes are not decided by courts at first instance: under Section 9(2) read with Rule 30, Citizenship Rules, 2009, the Central Government determines whether, when and how foreign citizenship was acquired, following Schedule III procedure [2][4].

Thus India permits only single citizenship, and OCI is the calibrated middle path that engages the diaspora without diluting sovereign allegiance. Extending it further — as diaspora bodies periodically urge — would require amending Article 9 itself, a step best weighed against the constitutional value of undivided loyalty that single citizenship secures.
