Applying for British Citizenship as a Child
British by Descent
Where a child is born abroad and at the time of the birth the child’s parent is a British Citizen otherwise than by descent, the child is eligible to make an overseas British passport application. The HMPO will expect to see evidence that both parents were together at the time of conception.
Lived in the UK until the age of 10
A child who was born in the UK, has spent 10 years in the UK with no more than 90 days outside of the UK during the first 10 years of his life and is of good character, will be eligible to apply for registration as a British Citizen. Once this application is granted, the child can then apply for a British passport.
Granted ILR after Child was Born
The child can be registered as a British Citizen if one or both parents were granted ILR after the birth of the child.
Child has lived in the UK for the Last 5 years
An application to register as a British Citizen can be made where the child and the child’s other parent are all settled in the UK. You are required to have lived legally for the last 5 years and the child is required to have been settled for 1 year.
