MOVING TO BERLIN - OFFSHORE WORK - VISA (Berlin)

Guten Tag,

I intend moving to Berlin next year. I am Brazilian citizen with an international contract working in Africa. I only have Brazilian citizenship.

I lived in Germany for one year in Protected content as an exhange student and had a student´s visa. Do you know which Visa I can apply for?

I would only be living 6 months in Germany, since I work on a 28x28 days rotation.

Thanks in advance,
