Brazilian Visa Expiry Question

Hello - I have a Brazilian Visa issued 23 July 2010
Type: Vitem II (type 2 business)
stay duration: 90 days
at bottom it Says " visa valid for 10 years" max 180 days per year   -- my last trip was in Aug 2010 for 6 days

I am just double checking on information for if it is still valid or if i need a new one --- (it is the NEW type of VIsa with my photo and all my passport Details entered on it)

I have just been asked to give a presenation at a meeting in June (same reason I went back in 2010)

Any thougths???  I am a US citizen and i reside currently in the US

Sorry, but you should read your visa again and ask yourself if it's still valid and you should have the answer. 

Short answer is Yes. 

The math:
The Visa is Valid for 10 years from July 2010 makes it valid until 2020.
Last entry 2010.  2013 is before 2020.

It says on your visa it is valid for 10 years.  Seriously, why would you be worried?

Primarily b/c more than once I have had issues with Brasil....  I just wanted to be absolutely SURE!!!

Your Visa is valid.  If you are worried about specific issues please feel free to post them.
