I'm an EU citizen living in Berlin, and my partner is visiting me in few months. He wanted to stay for the full three months (as tourist) due to my depression. However, my partner only have one month of vacation, meaning he would have to work remotely for the last two months while here in Berlin.
He is an Argentinean full-time programmer in a non-EU company, so technically it is feasible, but would that work legally? The problem I can see is regarding taxation, but we wanted to know if there is any way to make it work.
