Learning to fly in the country where you are going to fly isn't always an option.
For example, i live in Norway, but am a British Citizen. I speak a little of the local lingo, but by no means enough to sit the PPL exams. Thus, i am off to AAA in September to take my PPL and then to transfer my license to Norway upon my return.
I am however having regular lessons at the local club here, which is introducing me to the flying in the area where i will eventually fly - but i cannot complete the course here.
