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?
Well, yes of course. Some relatives have few foreigner coworkers and they seem to be happy. (tho I don’t know them personally). Also I’ve met some foreigners through university and they seem to adapt well. But I guess it heavily depends on what kind of lifestyle you want to have.
People are usually warm and we appreciate it if you show interest in our culture and adapting here. You should be more than fine if you are mindful to that and better still if you are naturally outgoing. Good luck and hope you find a cool place to go, or things get better if you end up not moving.
