Question to the Home Office:
To ask His Majesty's Government how many children currently residing in the UK (1) do not have a British citizenship, (2) do not have legal permission to live in the UK, and (3) are entitled to register as British citizens under the British Nationality Act 1981 but have not yet done so.
The current immigration status of a child currently resident in the UK or their potential entitlement to register as a British citizen depends on their individual circumstances. Therefore, this data is not available.
