OCI is not dual citizenship.

OCI and PIO: links with the diaspora, not dual citizenship

Quick answerIndia does not allow dual citizenship. For people of Indian origin abroad, it gives the OCI card: a lifelong visa with many rights, but no vote and no constitutional posts. The CAA, 2019 fast-tracks citizenship for six minority communities from three neighbouring countries.

Like a lifetime guest pass to your old school: you can visit any time and use the library, but you cannot vote in the student council.

India does not allow dual citizenship. To keep ties with people of Indian origin abroad, it created two schemes, and later merged them.

	PIO card (1999/2002–2015)	OCI card (2005 onwards)
For	Persons of Indian origin (up to the fourth generation) holding foreign passports, except of certain countries	Foreign citizens who were, or were eligible to be, Indian citizens on or after 26 January 1950, their children and grandchildren, and foreign spouses of Indian citizens or OCIs
Visa	Visa-free travel for 15 years	Lifelong, multiple-entry visa
Status now	Withdrawn in January 2015; PIO cardholders treated as OCI	The single diaspora scheme since the Citizenship (Amendment) Act, 2015

An OCI cardholder cannot:

vote or contest elections;
hold constitutional posts such as President or judge;
normally hold government jobs;
buy agricultural land or plantations.

A person whose parents or grandparents were citizens of Pakistan or Bangladesh is not eligible. An OCI card can be cancelled, for instance for fraud or for violating Indian law, after giving the cardholder a hearing (2019 amendment).

Trap: ‘OCI is dual citizenship.’ False. An OCI is a foreign citizen with a lifelong visa and some parity with NRIs; he is not an Indian citizen.

What UPSC asks: Prelims: OCI benefits and limits (no voting, no constitutional posts); PIO merged into OCI in 2015. Mains: diaspora policy and the dual citizenship demand. Next likely angle: OCI rights such as farmland purchase or the special permit rule for some activities.

→ Indian diaspora (International Relations) Why OCI matters for diaspora policy.

Amendments, CAA 2019 and the Assam question

1986	Birth rule tightened	From 1 July 1987, one parent must be a citizen.
1992	Descent through the mother	Either parent’s citizenship now counts for birth abroad.
2003	Illegal migrant, OIC, NRC	Defined ‘illegal migrant’; barred illegal migrants from most routes; enabled a national register.
2015	PIO merged into OCI	One diaspora card.
2019	Citizenship (Amendment) Act	Faster citizenship for specified minorities from three neighbouring countries.

The CAA, 2019. The Citizenship (Amendment) Act, 2019 says Hindus, Sikhs, Buddhists, Jains, Parsis and Christians from Afghanistan, Bangladesh and Pakistan who entered India on or before 31 December 2014 will not be treated as illegal migrants.

It cuts the naturalisation residence requirement for them from 11 years to 5 years.
It does not apply to the tribal areas of Assam, Meghalaya, Mizoram and Tripura under the Sixth Schedule, or to areas under the Inner Line Permit.
The rules were notified in March 2024.
Critics say it brings religion into citizenship and leaves out other persecuted groups. The government says it helps minorities persecuted in those three countries and takes nothing from any citizen.
Petitions challenging its validity have been filed in the Supreme Court.

In Re: Section 6A of the Citizenship Act, 1955 (2024). By a 4:1 majority, a Constitution Bench upheld Section 6A, added in 1985 after the Assam Accord. It gave citizenship (directly, or after registration and a waiting period) to migrants who entered Assam from Bangladesh before 25 March 1971. Why it matters: the cut-off date for Assam stays 25 March 1971, unlike the rest of India.

NRC. In Assam, the National Register of Citizens was updated under Supreme Court supervision. The final list, published on 31 August 2019, left out about 19 lakh applicants.

Mains frame. For CAA or NRC questions, explain the law first (dates, countries, communities, exclusions), then the two sides with Art 14 at the centre, then the pending judicial review.

Mains 2026 joined citizenship to elections: is the right to vote a fundamental right, and can the Election Commission examine the citizenship of voters?

Art 326 limits adult suffrage to citizens aged 18 or more.
The Supreme Court has treated voting as a statutory right under the RP Acts (Jyoti Basu, 1982; Kuldip Nayar, 2006).
A non-citizen cannot be registered (Sec 16, RP Act, 1950).
Lal Babu Hussein (1995): a person on the roll cannot be struck off on suspicion of foreign nationality without notice and a proper inquiry.
The Commission’s 2025 Special Intensive Revision of Bihar’s rolls, which asked many voters for documents, was challenged in the Supreme Court on these questions.

With reference to India, consider the following statements :

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 the citizenship cannot be deprived of it under any circumstances.

Which of the statements given above is/are correct?

Answer (a) & explanation

Only statement 1 is correct (a). Statement 1 is right: India has single citizenship, and the Supreme Court (in Pradeep Jain, 1984) has said there is only one domicile, that of India, not of each State. Statement 2 is wrong: Article 58 needs the President to be a citizen, not a citizen by birth; naturalised citizens are eligible too, unlike in the US. Statement 3 is wrong: under Section 10 of the Citizenship Act, 1955, a naturalised or registered citizen can be deprived of citizenship, for example for fraud or disloyalty.

Notice the ways to gain citizenship: birth, descent, registration, naturalisation and incorporation of territory. The Citizenship (Amendment) Act, 2019, with rules notified in 2024, eased naturalisation for some groups.

Trap

statement 2 borrows the US rule (natural-born citizen) and applies it to India.

Consider the following statements :

1. Aadhaar card can be used as a proof of citizenship or domicile.
2. Once issued, Aadhaar number cannot be deactivated or omitted by the Issuing Authority.

Which of the statements given above is/are correct?

Answer (d) & explanation

Neither statement is correct (d). Statement 1 is wrong because Section 9 of the Aadhaar Act, 2016 says the Aadhaar number is not proof of citizenship or domicile. Any resident, including a foreigner who has lived in India for 182 days in the past year, can get one. Statement 2 is wrong because the Act lets UIDAI omit or deactivate a number in cases set out in its regulations, such as fraud, duplicate entries or biometric problems.

In Puttaswamy (Aadhaar, 2018), the Supreme Court upheld Aadhaar for welfare and PAN linking. It struck down Section 57, which had let private firms demand it. Notice the recent debate during the SIR of electoral rolls (2025): the Supreme Court let Aadhaar be used as an identity document, but not as proof of citizenship.
