I want to live in Germany with my wife (same nationality as me), but work in Switzerland (and stay in a flat in Zürich) during the week.
I know I will need a Grenzgänger (cross border commuter) permit for Switzerland.
If my job was in Germany, I would qualify for a Blue Card (I have a degree, and my salary clears the minimum very comfortably). However it is not clear that I can apply for a Blue Card on the basis of a job in Switzerland.
What options are open to me?
(Background: I am already doing this - but we are British citizens, which means at least until 29th March we just use free-movement rights. On 30th March there is a frighteningly high chance we are going to cease being an EU/EEA national. Germany and Switzerland have both promised transition arrangements, but we may well fall in the cracks.
I would like answers to this question to concentrate on the options open to general 3rd-state nationals (eg from India or USA). If necessary, I can ask another question about how to make use of transition arrangements.)
