As someone who meets the third condition (one parent a US citizen and lived there for more than 5 years), it was really hard to convince the US that I was a US citizen. Every one I talked to told me to go to a country I hadn't been in since I was 5 and apply for citizenship through family sponsorship. This was more than 20 years ago and no one threatened to deport me.
After trying to get citizenship without leaving the country for about a year, I went to the post office and applied for a passport again, with every document that could possibly be relevant. The post office person looked through my pile of documents, declared my mother's passport good enough, stuffed it in the envelope, and a passport came in the mail for me. I think you may have explained to me how that worked out.
Countries were not vaccinating permanent residents? I had no problem getting a vaccine as a foreigner in Turkey. I thought all countries would be like that.
I live abroad and I'm not rich. I sometimes debate renouncing my US citizenship, but working remote in the US makes me well off here. If I had a local job making piles of money I might be more inclined to. My only complaint is that when I go to visit mom, I get endless grief from the immigration officials.
