GL,
I can't find anything in your previous posts that say you are Nigerian. Could I give you some friendly advice ? If you want pointers from the people who post here, you need to give all the pertinent information to get a reasoned response.
Now we know, if you are interested in Bristow I would say your best bet is to apply by e-mail direct to the Operations Manager in Lagos in the first instance. You will get a straight answer from him.
