Where Brazil sits in the global picture
Korea's E-2 visa and many Gulf employers have commonly restricted standard teaching roles to a short list of passports (UK, Ireland, USA, Canada, Australia, NZ, South Africa), which doesn't include Brazil. This is a real, structural barrier for those specific markets, not a paperwork issue you can work around with a stronger application.
Outside those markets, the picture changes. Vietnam, Cambodia, and Thailand generally have fewer nationality-based visa restrictions for teaching, focusing more on degree and TEFL qualifications than a specific passport list.
