Good point by Paco, look at the emerging markets and the offshore industry growing and growing in SA, East/West Africa. Boom time is coming, but be careful, some companies in these area's operate under a euro AOC so FAA won't count but on the other hand some will except you with a ICAO. You'll just end up doing a Airlaw exam or not and bob's your uncle a local ticket.
But as ever its getting your foot in the door and its the classic case of who you know! Or in some cases who doesn't know you.
