Gummaark....
Have a read of
this.
Ok, believe me it will be hard work. The costs will be astronomical since you don't have any
multi pilot time. In other words, sadly, your experience will not translate into a JAR ATPL.
You will have to do the 14 exams, no exemption on time in the classroom - either full time or distance learning. You'll have to do a full IR again (you get 5 hours off on 55 hours) and more than likely you'll have to do a MCC rating too. All very very expensive.
Your hours are good but at the moment there are a lot of turbine experienced guys running around here with no job. I'm one of them. (although it is looking pretty good for me soon). I *still* haven't finished.... If you think CASA can generate delays, you haven't met the CAA! The employment scene is looking better than what it did 9 months ago. However, it is still not as good as it was in 1998.
Also, on the immigration front, for me it was a doddle. I just walked in because I got a British Passport. I was lucky, Dad was a Brit. Since you are going for "right of abode" you'll have to prove to the British Govt that you can support yourself for the length of your study and then some. Plan about 12-18 months!
I can't get any benefits because I haven't paid any thing into the NI. (I don't want any thing actually).
I wish I could tell you something better but I am telling you the truth. I would not come over here without turbine time. If you really feel the need for a JAR lic, do the study by Distance Learning and keep flying.
