Do Brazil passport holders need a visa to visit BD?

Yes, a Brazilian ordinary passport holder needs a visa to enter Bangladesh. Brazil is not eligible for Bangladesh's visa-on-arrival or e-visa channels, so you must obtain a tourist visa in advance from the Embassy of Bangladesh in Brasilia before you travel. Bangladesh requires Brazilian ordinary passport holders to obtain a visa in advance for tourism. Brazil is on the list of countries whose citizens "must obtain a visa in advance" and is not among the nationalities (USA, Canada, EU, Gulf states, several Asian countries, etc.) eligible for Bangladesh's discretionary Visa on Arrival. There is no full online e-visa that replaces the embassy process; the Bangladesh online portal (visa.gov.bd) is used to fill and print the form, which must then be submitted with documents and fee to the Bangladeshi mission. Brazilians apply at the Embassy of Bangladesh in Brasilia. The tourist (T) visa is typically issued single-entry for a short stay, with multiple-entry options available; fees are reciprocity-based. Bangladesh is not part of the Schengen Area, so the Schengen 90/180 rule and ETIAS do not apply. Be conservative: do not rely on visa on arrival as a Brazilian, since it is not offered to Brazilian nationals.
