I had a school mate when I was doing my PPL who was from Russia.It was in Spain and I remember him saying that pilot school in Russia are quite a mess in terms of syllabus.
As they said, it all depends on the money you have available to spend on your training.Cadet program cost over 100k.Going modular you save 30-35k.
I would suggest to start looking and contacting flight schools in a specific country and book a medical in that country as well so that you can save money and time in bureaucracy conversion.I think in Sweden there are schools that accept students from all over the world.
