European Champ,
What part of the world doesn't have lots of Greeks?
A word of advise regarding work opportunities in the flying industry; there are not many jobs going anywhere in the world unless you are well experienced with good type ratings and good hours on type. Do not think, that you can travel to foreign countries to find work with no contacts and no local knowledge. If it were so easy, I think every one would be doing that. Africa is not a continent that you can just book a ticket to and arrive, make your way around and get contacts. Things work slightly differently here then they do in Europe.
The flying scene in Africa is so small in comparison to Europe or the States that all the available slots get taken before they even open up to the public. The flying community is small and jobs go to mates first before they get offered to outsiders. So use your contacts in Europe, get some experience and if you still want to experience Africa later, then you can always try again when you have some experience.
You might see the advice as very pessimistic, but honestly its for the better. You will just waste money, time and maybe more if you just arrive in Kinshasa.
