Isnt that how the Facebook/Google/Msft works right now with visa sponsorship and their remote hiring/working policies?
My friend working for Google moved later to Paris, France because she could and is still working for Google in France, I think companies like Facebook (in Ireland and certain European countries) or Google (literally everywhere in Europe) or even IBM (IBM has quite a few major offices in Asia, not sure why) already practice open border policies as part of a much wider remote working policy and have people from different countries working in different countries (aka somebody Spanish working in US while someone from US working in Ireland for example).
