You’re gonna need a lot of money or move to a shitty place.
What happens when you need some kind of medical treatment?
“I have my U.S. insurance”
And that will work in Slovenia?
“But they have universal health care!”
But it isn’t free. It’s paid through taxes and if you’re not a citizen or official resident you’re going to end up in a world of trouble. Maybe not financially, but with red tape and bureaucracy. I could go to Slovenia and just stay there, because as a Swedish citizen, they’ll have to honour that I’m part of the EU. So I get emergency treatment which is then billed to my country. How would that work out for you?
Or you get in a traffic accident. Is it your car? Rented? Is your license valid in that location? You might not be at fault, but there’s going to be questions asked. And how about banking?
“I have my account with CitiBank and my card.”
Sure, and withdrawal fees, conversion ASF can be a bother. Better to have a local bank and the money transferred with the SWIFT/IBAN network, so you get the most band for your $.
There are so very many minor everday issues that you simply never think about in your everyday llife. Living as an undocumented person and trying to actually live is not a great way to spend your time.
Another thing is languages. Americans are (sorry to say) not known for proficiency in languages apart from English. Now English is the de facto lingua franca of the world•, and in many places you can get by really well without knowing the local lingo. But why would you? I’m not talking about ‘Ugly Americans,’ but your life in another country will be so very much richer if you can partake in daily life. Gabbing with the neighbor, talking to someone in the local café about yesterday’s game. Little things. But you live there now.
I don’t know if @Cervaise has picked up the utterly weird Luxembourgian language••, and I’m sure English serves him well, but my guess is that if he and the family know some German or French, their lives are a lot easier.
• Fun aside: Since Brexit, English has suddenly been reduced to a minor language in the EU. It’s the official language for Ireland, Malta (and probably Cyprus), so around 6M. In spite of that, it is the unofficial working language in the corridors in Brussels and Strasbourg. A Croat and a Dane will chat in English over coffee, even if all official dealings are done with interpreter (I know one of them).
••Luxembourgian is this really weird mix of French and German where, if you know some of either language, it sounds as if you should be able to pick out some stuff, but soon realize that no. No you cannot.
