There's also a difference in push/pull: Germans will often expect you as the new guy to make the first steps, whereas that will be the opposite in other cultures that are more inviting.
Joining some Verein or taking a class at the Volkshochschule can help crossing that first circle.
Someone explained to me that this is the case in Sweden as well, but during covid (even though we had lighter restrictions), meeting people on any circle has been near neigh impossible.
Everywhere's still low compared to the Bay Area, don't get me wrong. But it means you either need to be a salary maximalist, determined to nationalize, to have a strong pull toward a certain US city/company for the move to make as much sense these days.
Still, I'd encourage everyone regardless of home/destination to live and work at least some of their life in another country. The merits of doing so are vast, and extend well beyond renumeration.
