My cousin was 16 years old when her mother became naturalized 10 years ago. At the time, her parents were divorced, and she lived with her father, who had official custody, and her mother had visitation rights. The father is a permanent resident, with no plans of getting his citizenship any time soon. I pointed out to my cousin that she may already be a citizen, based on her mother's citizenship. She seems to think otherwise, since her father was the one who had custody of her. Can anyone shed some light on this situation?
