I work for a European company, and this year started travelling to Brazil visiting factories to which we have supplied equipment. I obtained a VITEM-V visa and stayed in Brazil for 11 days this June (2016). When I had the visa registered at the federal police, I asked how long the visa was valid for. They explained that the visa was valid for 90 days independent of how many trips I made, ie I now have 79 days left.
This sounds unlike any other visa procedure I have heard of. Can anybody explain?
