Brief Outline:
The Constitution of India does not allow holding Indian citizenship and citizenship of a foreign country simultaneously. Based on the recommendation of the High Level committee on Indian Diaspora, the Government of India decided to grant Overseas Citizenship of India (OCI) commonly known as 『dual citizenship』
Persons of Indian Origin (PIOs) who migrated from India and acquired citizenship of a foreign country other than Pakistan and Bangladesh, are eligible for grant of OCI as long as their home countries allow dual citizenship in some form or the other under their local laws.
A person registered as OCI is eligible to apply for grant of Indian citizenship under section 5(1)(g) of the Citizenship Act, 1955 if he/she is registered as OCI for five years and has been residing in India for one year out of the five years before making the application.
Benefits to an Overseas Citizen of India card holder:
A multiple entry, multi-purpose life long visa for visiting India.
Exemption from registration with local police authorities for any length of stay in India.
Parity with Non-resident Indians (NRIs) in respect of economic, financial and educational fields except in relation to acquisition of agricultural or plantation properties.
