Need help assistance for settling in Brazil

Hi everyone, I have just joined to this Group and I found it amazingly useful and interesting. I am an expatriate in Belgium, and I will move in Jan for a mission in Brazil - Sao Paolo. I will go alone, family remaining here, for Protected content .

I have accepted with the only condition to be a detache, my package staying here the same, no residency interruption in Belgium; each 7 weeks, one will be worked in BE.

My question now is: is somebody working in Brazil in this way, as a temporar detache for a short mission? Does anyone knows a consultant which can help me with what possibilities I have? I know that Brazil is acomplicate country in terms of taxes and administration, so I need to consult as many opinions as possible.Thank you very much in advance!
