Are you based out of Sebring?
Well there is not much you can do in the US to help him with the process once he is back in Brazil.
When he gets back to Brazil all he really needs is an FAA CPL AMEL IR, no SE, when he does the conversion and he does the ckride in a ME he will get the SE anyway. Would be nice if you are able to do some NDB training, even if just in an FTD, since that`s is all he will be tested on when he gets back.
You don`t have to worry about hours since even with part 141 he will have way more hours then any Brazilian fresh CPL holder.
