I am a US citizen. In 2012 I was studying in Buenos Aires and got a VISA at that time to go to Brazil for a short trip. I am going back to Brazil next month for World Cup and am trying to figure out if my VISA is still valid. At the time, I thought they said it was good for multiple entries over 10 years but now as I look closely at the VISA, there is not any actual expiration date on the VISA. There are stamps for entry and exit in May of 2012. The VISA has my picture on it. It say it is a multiple entry. Type is Vitur. Duration of stay: 90 days. At bottom it says: VISA valid for 90 days from first day of entry into Brazil. Maximum stay: 180 days. Can you tell me how I would determine if it is still valid.
Thanks!
