there are specific work visas for teachers, researchers, scientists, visitors travelling to brazil to attend professional training, reporters, and movie crews, athletes and sport/game competitors, that all broadly fall under the generic work visa classification. 

the most common work visas is the permanent visa, or a visto permanente, which is a five-year visa geared mainly toward business-owners or managers - it is granted to those who have direct responsibility for managing and decision-making within a company.

permanent visas are issued to administrators, managers and directors of professional or business corporations, who are already employed by the company and are moving to brazil on intra-company transfer.
