job prospects
Just send your CV off to Bristow & CHC and see what they say.
Normally they want you to be type rated on something that they fly in Nigeria, ie Bell 206, 407, 412, Sikorsky S-76, EC-155, Dauphin, Super Puma 332 & 225, S-92. Also expats are generally hired as Captains. If they don't you will get an idea of what you need to be sucessful in finding a job offshore. But you never know until you try! Good Luck!
