Documents by Mail

The Consulate General of Brazil will receive correspondence sent by the U.S. Postal Service as well as all courier services (address the envelope to the attention of the Legalization Section).

However, the Consulate will only return documents via the U.S. Postal Service, such as Priority or Express Mail. Applicants must therefore enclose a self-addressed stamped envelope for the return of their documents. The Consulate cannot be held responsible for lost or delayed mail.
