Oh dear. Well, since you mention that you need to apply for a visa, I take it that you are not Kenyan.
In this case, this thread should answer your question about becoming a professional pilot in Kenya. Read it, and weep!
There is no chance whatsoever in any East African airline for foreigners, and my advice is to forget about becoming a bush-pilot if you ever want to get into a serious airline later on in your life.
A visa will allow you to live in Kenya, but getting a work-permit (without buying it) is impossible. No respectable company will employ you without it.
Good luck if you want to try anyway, but I'm afraid no-one here can help you. Otherwise, we all would be there now ourselves.
But you're welcome to sign our letter to Santa Clause.
