Mauritius has one of the largest Indian-origin populations of any country in the world -- commonly cited at roughly two-thirds of its population, tracing to 19th-century indentured labourers -- but Mauritius does not permit its own citizens to also hold Indian citizenship, so an Overseas Citizen of India (OCI) card, not dual citizenship, is the standard route for a person of Indian origin in Mauritius to retain a lasting legal connection to India.
Mauritius's uniquely large Indian-origin population
Mauritius is widely cited as having the largest proportion of Indian-origin residents of any country
outside India itself -- commonly put at roughly two-thirds of the population -- tracing back to 19th-century
indentured labourers brought to work Mauritius's sugar plantations after the abolition of slavery. This deep,
multi-generational connection means many Mauritians of Indian origin are not NRIs in the tax-residency sense
(they are Mauritian citizens, often several generations removed from India), but frequently still engage this
platform's guides in connection with inherited property, ancestral succession matters, or business ties back
to India.
Why OCI, not dual citizenship, is the relevant status
India does not permit dual citizenship for anyone, and Mauritius similarly does not allow its own citizens
to simultaneously hold another country's citizenship. For a person of Indian origin who holds Mauritian
citizenship, an Overseas Citizen of India (OCI) card -- not full Indian citizenship -- is the applicable route
to a lasting Indian legal status: OCI confers lifelong multiple-entry access to India and parity with NRIs on
several economic, financial, and educational matters, without conferring voting rights, government
employment eligibility, or the right to hold agricultural land.
Registering an OCI application from Mauritius
OCI applications from Mauritius are processed through the Indian High Commission in Port Louis (or online
through the OCI portal, with the physical passport later submitted for the sticker/booklet), following the
same national OCI Rules that apply from any other country, including the 2026 amendments that moved
applications further online and clarified that a minor cannot simultaneously hold both an Indian passport and
a foreign passport.
Common mistakes made on this point:
- Assuming Mauritian citizens of Indian origin can hold both Mauritian and Indian citizenship
simultaneously -- neither country's law permits this.
- Confusing OCI with a visa -- OCI is a distinct, more durable status conferring lifelong multiple-entry
access, not a time-limited visa.
- Not renewing an OCI card's linked new passport details after a passport renewal, which can cause
travel document mismatches.
