If it`s gonna be a commercial operation, then the airplanes are going to have Brazilian registration, at the present time you have to be Brazilian to legally act as commercial pilot (you can get a license as a legal resident but not use it for hire). There could be some loop holes, like if it`s a single pilot operation, you may be able to sit in the right seat, but unless it`s a multi crew operation/which it would not be in this case it`s really hard to demonstrate those logged hours.
