I don't know for certain. My father is still alive so I can ask him. He definitely has an American passport, though.
No, I lost it.
I was born before 1983.
1. Yes, I lived with them throughout; my father was a naturalized US Citizen and my mother was a Permanent Resident.
2. Yes, they were and continue to be married. They married before I was born.
Is it possible that I am a US citizen as I have one parent who became a US citizen whilst I was a permanent resident under the age of 18, then residing in the US, and under their legal care?
