British overseas citizenship is a category of citizenship that was created by the British Nationality Act 1981, which came into force on 1 January 1983.

You became a British overseas citizen on 1 January 1983 if:

• you were a citizen of the United Kingdom and Colonies on 31 December 1982; and
• you did not become either a British citizen or a British overseas territories citizen on 1 January 1983.

(Before 26 February 2002, the British overseas territories were known as the British Dependent Territories, and British overseas territories citizenship was known as British Dependent Territories citizenship. On this page, we refer to it by its current name, British overseas territories citizenship.)

In most cases, you became a British citizen on 1 January 1983 if you were a citizen of the United Kingdom and Colonies by birth, descent, legal adoption, naturalisation or registration in the United Kingdom, or if you lived in the United Kingdom, while a citizen of the United Kingdom and Colonies, for at least five years at any time before 1 January 1983.

In most cases, you became a British overseas territories citizen on 1 January 1983 if you were a citizen of the United Kingdom and Colonies by birth, descent, legal adoption, naturalisation or registration in a place that was a British overseas territory on 1 January 1983.

If you were a British overseas territories citizen only because you had a connection with Hong Kong, you lost that citizenship automatically on 30 June 1997, when sovereignty returned to China. But if you:

• had no other nationality, and would have become stateless, you became a British Overseas citizen on 1 July 1997; or
• were born on or after 1 July 1997, and would otherwise have been born stateless, you were a British Overseas citizen if, when you were born, one of your parents was a British National (Overseas) or a British Overseas citizen.

Special rules were introduced in 1986 to allow British overseas territories citizens from Hong Kong to acquire the new status of British (national) overseas. Those who did not register as British nationals (overseas) and had no other nationality or citizenship on 30 June 1997 became British overseas citizens on 1 July 1997.
