Some EU countries have pathways to citizenship/residency, but they are not easy. Such a path will usually involve being hired by a local company to do some type of specialized work that cannot be hired for locally. A highly skilled tech job is usually what that looks like. The other option for some countries (like Spain or Portugal) is to be wealthy and purchase a large amount of real estate in the country.

There was a subreddit called Amerexit that was an excellent resource for this information. I haven’t seen anything similar on Lemmy, though. If you see such a community, let me know!
