India does not permit dual citizenship, so an Overseas Citizen of India (OCI) card -- not a passport -- is the closest lifelong-visa status available to a former Indian citizen or their descendants; the PIO card scheme was fully merged into OCI back in 2015, and OCI comes with broad practical benefits but excludes voting rights, most public employment, and agricultural land ownership.
OCI is not dual citizenship
Sections 7A to 7D of the Citizenship Act, 1955 govern the Overseas Citizen of India (OCI) scheme. OCI is
explicitly not a form of dual citizenship -- India does not permit dual citizenship in any form -- but is
instead a lifelong, multiple-entry visa-equivalent status for eligible foreign nationals of Indian origin (or
the foreign spouse of an Indian citizen or OCI cardholder, provided the marriage has subsisted at least two
years), along with certain descendants. It exempts the holder from Foreigners Regional Registration Office
(FRRO) registration, gives parity with resident Indians on domestic airfares and monument entry fees, and
permits property purchase except agricultural land, farmhouses, and plantation property. Persons of Pakistani
or Bangladeshi ancestry are specifically ineligible for OCI.
What OCI does not confer
An OCI cardholder cannot vote, cannot hold a seat in Parliament or a state legislature, cannot hold
constitutional posts such as President, Vice-President, or judge of the Supreme Court or High Courts, cannot
generally hold government or public-sector employment, and cannot obtain an Indian passport. Certain activities
-- mountaineering, missionary work, journalism, research, and travel to Protected or Restricted Areas -- still
require prior special permission even for OCI holders, a restriction the government has periodically
tightened. OCI cardholders are also treated as foreign nationals for the purpose of many sector-specific
Indian regulations -- for example, certain categories of defence, telecom, and strategic-sector investment
that are restricted or subject to additional approval for foreign nationals generally -- so an OCI holder
planning a significant Indian business investment should confirm the applicable sectoral rule rather than
assuming OCI status is treated identically to full Indian citizenship for that purpose.
PIO cards -- fully merged into OCI, with no reversal
The Person of Indian Origin (PIO) card scheme was discontinued effective 9 January 2015, with existing PIO
cards treated as equivalent to OCI cards for policy purposes; this merger remains in force with no reversal.
Since 30 September 2019, physical PIO cards have stopped functioning as valid travel documents altogether --
anyone still holding an unconverted PIO card should convert to OCI, now at standard OCI application fees
(earlier conversion fee waivers have since ended).
Can I hold both an Indian passport and OCI status at the same time?
No -- OCI is available to foreign nationals, not to Indian citizens, because India does not recognize dual
citizenship. If you hold an Indian passport, you are an Indian citizen and OCI status does not apply to you;
OCI becomes relevant once a person has given up Indian citizenship and taken on foreign citizenship.
Can an OCI cardholder vote in Indian elections or hold public office?
No -- OCI status does not confer voting rights, the ability to hold a seat in Parliament or a state
legislature, or eligibility for constitutional posts such as President, Vice-President, or judgeships on the
Supreme Court or High Courts, and it generally does not permit most government or public-sector employment.
I still have an old PIO card -- is it still valid for travel?
No -- physical PIO cards stopped functioning as valid travel documents from 30 September 2019. If you still
hold one, you should apply to convert it to an OCI card, which is now the sole equivalent status, subject to
the standard current OCI application fees.
