Do I need a passport or visa to enter?
You will need:
A valid U.S. passport.
As of June 16, 2019, U.S. citizens do not need a visa if they are traveling to Brazil for tourism, business, transit, artistic or sport activities, with no intention of establishing residence.
For other types of travel, U.S. citizens may need to apply for a Brazilian visa either online here or at the nearest Brazilian consulate in the United States or abroad.
Brazilian law requires any minor who is a Brazilian citizen (even dual nationals who are both U.S. and Brazilian citizens) to have permission from each parent to travel within Brazil or exit the country. When a minor travels with both parents, no written authorization is needed. When the minor travels with only one parent or without either parent, s/he must have two original written authorization letters from each absent parent and carry a copy* of the child’s birth certificate or have an annotation in his/her Brazilian passport authorizing travel alone or with only one parent. Brazilian citizen minors without authorization letters and a birth certificate* or an annotated Brazilian passport likely will not be allowed by authorities to pass through immigration or to board a flight departing Brazil.
The U.S. Embassy and its consulates cannot intervene in Brazilian immigration matters or request that this requirement be waived for U.S. citizen travelers.
Written Authorization Letter: If the absent parent is in Brazil, written authorization letters must be in Portuguese and notarized by a Brazilian notary. If the absent parent is in the United States or elsewhere outside of Brazil, the authorization must be done at the nearest Brazilian Embassy or Consulate using the form provided by that office. Again, please note that Brazilian law requires two original authorizations for each absent parent. This is important, because Federal Police may request and retain one authorization upon the minor’s entry into Brazil. Authorities may then request the second original document upon the minor’s departure. Authorizations written in English or executed before a U.S. (or any non-Brazilian) notary public are not accepted by the Brazilian Federal Police. Similarly, birth certificates issued outside of Brazil that are not apostilled* and translated by a certified translator may not be accepted.
Brazilian Passport Annotation: In lieu of carrying authorization letters, parents of dual U.S.-Brazilian citizen minors may instead request an annotation be placed in the minor’s Brazilian passport authorizing the minor to travel with only one parent, or to travel alone or with a third party. This annotation replaces the requirement for written authorization letters until the passport expires. Parents residing in Brazil should contact the Brazilian Federal Police for details on obtaining an annotated passport. Parents residing abroad should contact the nearest Brazilian Embassy or Consulate. The annotated Brazilian passport must not be expired and must be carried along with the minor’s U.S. passport at all times for Brazilian Federal Police to accept it in lieu of an authorization letter. There is no comparable annotation available in U.S. passports.
Children who are not dual citizens of Brazil: Please note that, while Brazilian law related to travel authorization does not explicitly apply to non-citizens of Brazil, Federal Police have, at times, delayed the travel of non-Brazilian minors who lack appropriate authorization from both parents. For this reason, we recommend that families of non-Brazilian minors who may travel through Brazil without one or both parents execute written authorizations (following the instructions in the preceding paragraph) in advance of travel and ensure that the minor, or the minor’s traveling companion, carries the original or notarized copy** of the minor’s birth certificate.
