There should be both. I am German, work for an American company. It shouldn't be difficult for me to move to an US office for some time and return back home. Of course, there is some likelyhood, that if I stayed at a place for more than a coumple of months, that I want to stay at that place long term, and this should be possible without too high bareers. Here in Germany, you basically need a job offer which matches certain criteria, to be get a temporary residency. This can be prolonged as long as you stay employed in Germany. Similar rules exist for students. I have an Indian colleague who studied in Germany and now is working here. If you stay in the country for 5 years, it is pretty much just a formality to apply for unlimited residency and it is also reasonably straight-forward to even get German nationality, though this is less common.
