I have a friend living in Spain, who was born 65 years ago in India of a British father and a French mother. She has a British passport but would like to obtain French nationality too (Brexit fears).
She when born she had French nationality but her father ’on her behalf gave up her French nationalty’ leaving her with just British nationality.
I have searched the internet but have not found any good info. regarding these specific circumstances
I should be grateful if anyone can make suggestions.
