Because India does not offer dual citizenship, the children will have to convert to Overseas Citizenship of India if they also hold non-Indian citizenship.

Some well-known measures are a Ministry of Overseas Indian Affairs, the institution of the Overseas Citizenship of India (OCI) and the periodically held Pravasi Bharatiya Divas.

Moreover, people who have acquired citizenship in Pakistan or Bangladesh are not eligible for Overseas Citizenship.

British Overseas Citizenship is a form of British nationality under the British Nationality Act 1983.

Recovered Portuguese nationality in 1995, and was granted OCI (Overseas Citizenship of India) by the Government of India in 2007.

It will be replaced by two new categories - British Citizenship and British Overseas Citizenship.

Muttiah Muralitharan holds Overseas Citizenship of India (OCI) and he does not need a visa for travelling to India.

Therefore, Overseas Citizenship of India is not an actual citizenship of India and thus, does not amount to dual citizenship or dual nationality.

The introduction of Overseas Indian Citizenship does not entitle people who have acquired, or are planning to acquire, foreign nationality or to retain their Indian passports.

However, there are some minor benefits to having British Overseas Citizenship.
