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?
About language barriers: have you ever considered actually learning your host countries language?
Of course. But learning a language as an adult is a huge challenge. I take lessons but it’s slow progress, people aren’t always understanding when you stumble or don’t know words and I’m juggling full time professional work on top of it so time and mental energy are limited.
Even after years of practice I will never not sound like a foreigner, which is distancing.
There is no need to be perfect. But it at least shows effort. I have met people who lived here for 40 years and never bothered to learn even simple words or phrases. And that lack of effort, this absolute disinterest in ones host society is, in my opinion, highly impolite and antisocial.
In tech, is there really a need, though? All of this year’s new hires I’ve met communicate exclusively in English. No-one cares.
It might not be a job problem to just function, but not learning the local language makes you a bit anti-social in any other aspect.
