Passport & OCI Services
The visa Citizenship of India (OCI) is an immigration status authorized for a foreign citizen of Indian origin to live and work in the Republic of India indefinitely.
A stateless person cannot apply for an OCI, however there is an open question if an OCI holder can be considered stateless (if they lose citizenship of the other country), so in countries where citizenship to dual citizens can be revoked, such as Australia an OCI holder may be disadvantaged, however the lack of precedents in this area means that the issue is uncertain.
"OCI is considered to be citizenship of another State". The circumstance where a person in this provision is rare, as it means they hold a secondary form of British citizenship such as a British visa citizen and passport.
