furthermore, If a holder of a diplomatic visa is traveling to Brazil on an unofficial visit, then a tourist visa, if applicable, must be secured.

A letter from the country's corresponding governmental agency such as the Department of State, Ministry of Foreign Affairs, a diplomatic mission or international organization such as the UN or the Red Cross stating the purpose of the visit, dates of travel, duration of stay and contact in Brazil is necessary.

there is no fee or cost associated for a diplomatic visa, but the passport of the requesting traveler must be valid for at least 6 months beyond the visa's date of issue.
