Most paper Brazil visas are valid for 10 years. The fine print on your visa will indicate how many years it is valid. If your visa is valid for 10 years, you can travel with it even if the passport it is in expires, pending your name has not changed. Simply bring your old passport and new passport, when traveling to Brazil.
If you're not sure how to read your visa, scan and email a copy of it to us and we can assist you.
