Well before you even think about flying you need to get an RNE (e' la carta d'identita' per immigrati), you can get that in a number of ways, open a company in Brazil, marry a Brazilian, do a Stable Union with a Brazilian (relazione seria), get a kid in Brazil or get a sponsor (quasi impossibile in Aviazione). All this will take at least 5-8 months, before you are done with this you can't apply for the license conversion and you will not be able to take the ck flight if you don't have the actual RNE (it can take up to two years to get the actual final one). But as soon as you apply for the RNE you can start working...but not flying
In order to fly you need to get a validation of your High School Diploma (per la mia maturita' Italiana ci e' voluto quasi un anno).
After all this you can start with the conversion.
Stai in Italia che e' meglio.....
