Take it one step at a time.
Has she taken the TSE, TOEFL & TWE for English proficiency? I assume her training was in Portugese? She will need to pass all 3 to be eligible to sit for the NPTE in the state of Georgia. If the school taught in English, the state requires a letter from the school stating that the curriculum was taught in English. Each state has different requirements should you relocate for medical school. Keep that in mind.
Has she gotten her education evaluated by the FCCPT, IERF or ICA for US equivalency? They may require additional courses or may flat out deny the possibility of licensure. This should be done ASAP.
