It takes about 10 weeks if you are dealing with the UK CAA as I was. With others your mileage may vary.
You may be required to take another medical if your Medical is not from one of the two states you are transferring between. I had a Swiss medical and it took a little longer as the IAAs medical type person wanted some of the figures from the various examinations for a more detailed history I presume.
Also the small matter of the 400 odd Euro. The IAA has to pay fopr those final salary pensions after all!
We who fly do so for the love of flying. We are alive in the air with this miracle that lies in our hands and beneath our feet.
