How does a British Protected Person acquire British Citizenship?
A BPP who has no other nationality or citizenship and is not living in the UK can apply for British citizenship by registration under section 4B of the British Nationality Act 1981. This will make them a British citizen by descent, and thus unable to pass British citizenship to any children unless they are born in the UK. A BPP who has lived in the UK for 5 years and had Indefinite Leave to Remain for 1 year can apply for British citizenship by registration under section 4 of the Act. If they are married to a British citizen and have Indefinite Leave to Remain, they can apply for British citizenship by naturalisation after living in the UK for 3 years.
