What changes when you take another country’s citizenship, and the papers India expects.

Many NRIs eventually take the citizenship of the country they live in, for a passport that travels more easily, the right to vote, or security for their children. India does not allow dual citizenship, so that step ends your Indian citizenship and starts a short run of paperwork in India. Most of it is routine. Missing it tends to surface at the worst time: at an airport, at a bank, or when you try to sell a flat.
Under India’s Citizenship Act, an Indian citizen who voluntarily acquires another country’s citizenship usually stops being an Indian citizen from that day. You do not choose this; it happens by law. Your Indian passport stops being valid for you as a citizen, even if its expiry date is years away.
Two things follow. You must surrender the Indian passport and get a surrender certificate (sometimes called a renunciation certificate) from the Indian mission or its service centre in the country you live in. And if you want to keep a lifelong link to India, you then apply for an OCI card.
The certificate records that your Indian passport has been surrendered and cancelled. You usually need it to apply for OCI or an Indian visa, and banks and registrars may ask for it later. Apply through the mission’s service centre for the country you live in, with your last Indian passport, your new foreign passport and your naturalisation certificate.
Three points catch people out:
Check the page of the mission for your country for the current fee and checklist; our document checklist covers the OCI papers.
An OCI card is a lifelong visa for India for people of Indian origin and their spouses. With it you can usually enter India as often as you like, stay as long as you like and work or study without a separate visa. For money matters, an OCI cardholder is treated much like an NRI: you can usually open NRE and NRO accounts, invest, and buy flats and commercial property, though not agricultural land, a plantation or a farmhouse. Our guide to why NRIs cannot buy farmland explains that bar.
OCI is not citizenship. It does not give the right to vote, to stand for election or to hold most government jobs, and some activities, such as research or journalism in certain areas, need permission.
The rules on new passports were eased in recent years. Indian missions’ guidance says you usually no longer need a new OCI card each time you get a new passport before the age of 20. Instead you upload the new passport and a recent photo on the OCI portal, usually within three months of getting it. The same guidance still asks for the card to be re-issued once, when a new passport is issued after you turn 20. Some reports say even that has gone, so check the OCI portal before you travel on a new passport.
Keep the old passport that carries the OCI details, or that was used for the OCI application, with you when you travel until the card is updated. The renewals tracker can hold your passport and OCI dates, with a reminder in good time.
Your PAN stays valid after you change citizenship, but update the records so they show you as a foreign citizen, with your new passport details. You keep using the same PAN for Indian income, property and returns.
Aadhaar is for residents of India. A foreign citizen living abroad is not usually eligible to enrol, and rules on keeping an existing Aadhaar after a change of citizenship are not spelled out clearly, so ask UIDAI or your bank how it should be updated.
Tell your bank too. Your NRE and NRO accounts can usually continue, but the bank needs your new citizenship, passport and OCI details for its records, and some accounts may need re-documenting. Do the same with demat accounts, fund houses and insurers. Our NRI banking guide explains the accounts.
Property you bought while an Indian citizen usually stays yours after you take another citizenship, including property you could not buy today as an OCI cardholder, such as agricultural land you inherited. Selling it later follows the rules for OCI cardholders and NRIs, including tax deducted by the buyer; our guide to selling property in India explains the TDS.
This guide explains the usual position. Fees, penalties and OCI rules are set by India’s Ministry of Home Affairs and its missions and change from time to time, so check the official pages for your country before you apply.
