Brazil Travel Visa 

U.S. citizens must have a valid U.S. passport and a visa prior to entering Brazil. Upon arrival, you must fill out an immigration form that you need to keep with you for the duration of your stay and hand back to immigration officials when you depart the country. The U.S. government cannot assist you if you arrive in Brazil without proper documentation. Be sure to visit the U.S. State Department website for the latest travel advisories related to Brazil. And it’s always important when traveling abroad to understand the health and vaccination protocols outlined by the Centers for Disease Control.

Travel tips:
The “OK” hand gesture has an offensive meaning in Brazil. Keep valuables and larger banknotes tucked away in a money belt. Passports should be securely stored at your lodgings. Spanish is not the native language of Brazil and is not widely spoken as a second language. Portuguese is the official language of the country. Be aware that during certain times, the subways in the major cities have women-only cars. Men who enter these carriages during select times can be fined. Running red lights can be an issue in Brazil, so it's wise to always wait for cars to completely stop before crossing the road.
