GIS job market in Germany?

Long story short, I lived in Germany for 3 years on and off, but had to return to the US to finish my degree.

I speak German fluently and have already worked at an environmental tech company as an intern.

So my question is how is the job market for foreigners with a BSc in GIS? Is it likely I would run into visa problems?

I'm scoping out Master's programs as a backup, but nervous (or paranoid) I won't get accepted. And if that doesn't work, I'm contemplating a BSc. in comp sci. But I'm not sure if I want to finish school at 28.
