Hello!
I'm Brazilian, highly qualified engineer with a good job in Brazil. Despite all that, I hate living Brazil and I want to spend the rest of my life, legally in a civilised and organized country. I always look for job offers in my field (renewable energy) and often there are positions for it. Most applications ask if you have work permit, and most countries would permit an outside worker to have the job if the employer proves the potential worker has some unique skills. The point is, I have never seen any worker do that. Does anyone know why? Is there any liability/ tax the employer must compromise to in order to "invite" an outlander worker?
