NGL, not asking for a friend. Given the current trends in US politics, it seems prudent to at least look into it.
Most of the online content on the topic seems to be by immigration attorneys hustling ultra rich people. I’m not ultra rich. I have a job in tech, could work remotely, also have enough assets to not desperately need money if the cost of living were low enough.
I am a native English speaker, fluent enough in Spanish to survive in a Spanish speaking country. I am old, male, cis, hetero, basically asexual at this point. I am outgoing, comfortable among strangers.
What’s good and bad about where you live? Would it be OK for a outsider, newcomer?
Given that my country is Russia and you are probably trying to escape an authoritarian regime, you may consider another destination.
But still, I think Americans are generally welcome. People can make lighthearted jokes about it and be surprised, but you’ll be a welcome guest after all. Bonus points if you say American government, and particularly Department of State, is shit :D
Language barrier might be an issue - most Russians above ~35 have very poor English skills, and younger folks mostly have it on A2-B2 level.
Oh, and the country is sanctioned to hell, so sending money in and out is an additional hurdle. But if you retain your American credit card, you’ll be alright and at least able to make payments outside the country.
