Currently, Brazil travel restrictions include travel to Espírito Santo. Brazil has restricted the entry of all travellers who are not citizens, residents, government employees and their family members, immediate family members of citizens, diplomats, travellers with authorisation from the government, travellers with a National Migration Registry, or travellers in transit who do not leave the international area of the airport. Spouses of Brazilian nationals must have a Brazilian marriage certificate to enter the country. If the certificate is not issued by Brazil, it must be apostilled by a consulate and be accompanied by a non-official translation in Portuguese. Technical landings to refuel where passengers of restricted entry do not disembark may also enter the country. If you are planning to travel to Espírito Santo at this time, it is recommended that you stay up to date on current restrictions and follow proper safety measures while in public.
