PLA (Português Língua de Acolhimento)  is a government-defined Portuguese learning pathway that certifies A1+A2  (and higher routes). For nationality language proof, A2 is the minimum “sufficient knowledge” level , and AIMA states that PLA A2 (or higher) certification is accepted —meaning you can meet the requirement with a recognized course certificate rather than sitting a public exam. What PLA is (correct definition) PLA courses were created and regulated by Portaria n.º 1
