I am traveling to Brazil for the first time. I was told by the visa service that I have to get my visa w/in 90 days of landing in Brazil. My trip was postponed so now I will be outside ninety days from the date on my visa. The visa service tells me I have a problem, and yet a "seemingly" knowledgeable person at a consulate says I have a "new" type visa and the 90 day provision no longer applies. If it does not say on the face of the visa that I have to land w/in 90 days of the date on the visa am I still OK?

Does anyone have experience with a "new" versus "old" tourist visa and when/if such a change over really occured?
