> “Easiest” way is probably getting married to a citizen. I don't think that's the case, anymore. I remember a notorious case, around here, where a guy had a Russian wife (I have no idea of the background -but they were married for many years), he was dying of leukemia, and required her around-the-clock care, and they deported her.
Dude, there must be something incredibly specific about this case for this to be a thing. Like the wife just said she was a tourist and never left instead of applying for a green card. If you just do the paperwork - enter the US under a K1 Visa (fiancé(e) visa), get married, and then apply for a green card once you're married - you won't be randomly deported when your spouse gets leukemia. It is actually is very easy…
I knew a guy that had a Korean wife, legally in the US, but had been, many, many years earlier, swept up in a human trafficking thing.
That made getting citizenship difficult. Twice victimized.
