He would have qualified for the Immigration Reform Act of 1986.. Not going to cry any tears for people who are lax and don’t take care of their details. https://en.wikipedia.org/wiki/Immigration_Reform_and_Control_Act_of_1986
He was a kid. I doubt it came up in any conversations with his parents about this as he got older, so he probably had no point of reference for his own situation. How did he get his Green Card? That's a legal process. This seems to potentially be a BS story pushed by the media. I must be a racist because I'm siding with him because he is a white Polish guy instead of an African. Oh wait! I just remembered I'm not white either and spent 10 years and $15K in legal fees to get my Green Card!
He was 3 when he arrived in America. His parents became US citizens. If he was underage at that time, he may have had citizenship imputed. He can’t find the documents.
40 years is plenty long enough to have become a US citizen.
Whats the hold up, doc?
