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?
Depends how they behave. If they behave like “Expats”, who don’t care about integrating into our society, don’t care about learning the local language even after years, they are not welcome.
If they integrate seamless (and this does not imply giving up their identity, just to make sure), and become a good member of this society, be welcome.
