Citizenship in India
Naturalisation timelines, tests, and dual nationality
India does not permit dual citizenship: acquiring another nationality ends Indian citizenship automatically. Naturalisation exists in law after long residence but is granted to foreigners rarely and at the government's discretion. The Overseas Citizen of India card was created as a substitute for the diaspora, and although its name suggests citizenship, it explicitly is not.

Why there is no dual citizenship
Indian law treats the acquisition of a foreign nationality as terminating Indian citizenship, and it does so automatically rather than by any act of renunciation. A person in that position is required to surrender their Indian passport, and holding or using it afterwards is an offence.
The rule is the origin of almost everything else in this section. Because a very large diaspora had lost Indian citizenship by naturalising elsewhere, the state needed an instrument that restored the practical benefits of belonging without restoring nationality. That instrument is the OCI card.
What the OCI card is and is not
- It is a lifelong multiple-entry visa for India, with no limit on the length of any stay.
- It exempts the holder from FRRO registration however long they remain in the country.
- It gives parity with non-resident Indian nationals in most economic, financial and educational matters, and the right to work in most occupations.
- It is not citizenship. It carries no right to vote, no eligibility for public office, no Indian passport, and no access to most government employment.
- It does not permit the purchase of agricultural land, plantation property or farmhouses, which is one of the most commonly misunderstood limits.
- It can be cancelled by the government, and cardholders remain foreign nationals for every legal purpose other than the ones listed.
Who qualifies for an OCI card
Eligibility is built around descent and marriage: former Indian citizens, people whose parent, grandparent or great-grandparent was an Indian citizen, and foreign spouses of Indian citizens or of existing OCI cardholders after a qualifying period of marriage. Certain nationalities are excluded outright.
Applications are made through the government's OCI portal and processed by the Ministry of Home Affairs. Cardholders have periodically been required to re-issue the card after the renewal of a passport at certain ages, and the requirement has been changed more than once, so the current position should be checked before travel.
Naturalisation, in law and in practice
Citizenship by naturalisation exists in the Citizenship Act for applicants who have resided in India for a long qualifying period, including a continuous period immediately before the application, who renounce their previous nationality, and who satisfy character and language conditions.
In practice grants to ordinary foreign residents are unusual, the decision is discretionary, and there is no published timetable. A foreign professional should plan on the basis that Indian citizenship will not be available, rather than treating it as a distant milestone.
