Hi guys...
On the foreseeable future, I very much doubt that anyone could change the law in what comes to expat pilot hiring here in Brazil.
There are many type rated pilots (from GOL, TAM and WEBJET) furloughed due to the poor economic growth of the country and mostly because of the huge amount of government taxes that the companies have to pay.
So, my advice is: don't waste your time looking for a job here. Even for brazilian citizens, I believe that will be hard to get hired on the next 2 years...
