I am a citizen of Mozambique and I work for an American company. I will be traveling to Brazil representing my company for at least 10 times every year managing accounts. Is there a different way of getting a visa for up to 366 days on my situation?

I would only know of a working Visa. A Brazilian consulate in your town will answer all your questions. Good luck.

Thanks for responding Lisa. I think most of the times the work visa applies for situations were non Brazilian citizens get hired and work in Brazil and live there permanently. In my case is different. I live and work in US and our accounts are in Brazil, so the business visa is the most indicated one. However I cannot stay in that country for periods up to 180 days.
