Do Brazil passport holders need a visa to visit GW?

Brazilian ordinary passport holders need a visa for Guinea-Bissau. The recommended route is the official eVisa (RGB Electronic Visa System), which grants a single-entry stay of up to 90 days. A visa on arrival is also available but is less reliable, so obtaining the eVisa before departure is strongly advised. Guinea-Bissau does not grant visa-free entry to holders of ordinary Brazilian passports. The CPLP (Community of Portuguese Language Countries) visa exemption that lists Brazil applies only to diplomatic and service passports, not to ordinary tourist passports. For a short tourist visit, an ordinary Brazilian passport holder must obtain a visa. Two channels exist: (1) the official electronic visa (eVisa) issued through the Republic of Guinea-Bissau Electronic Visa Application System (RGB), which provides a single-entry visa valid for a stay of up to 90 days, and (2) a visa on arrival at Osvaldo Vieira International Airport in Bissau, which in practice generally requires a prior authorization letter from the Migration Office and is therefore less dependable. Because the eVisa can be applied for and confirmed before travel (typically within a few business days), it is the recommended option. A passport valid for at least six months on arrival and a valid yellow fever vaccination certificate are required for all travelers. Guinea-Bissau is not in the Schengen area, so the Schengen 90/180 rule and ETIAS do not apply.
