First of all, thank you all for yours post that were an enlightenment to me...
I already have the FAA groundschool theory, which I've been studying to take some doubts about aviation related issues. I will try to do get already in contact with some school in the U.S. I probably will go to the FAA+IR route, doing first the PPL training in the U.S then sitting for the JAA exams plus extra hours & 7 theoretical exams in German or doing JAA+FAA if any school can offer that option, and if there is enough time...
I think the flying part will be hard, and theoretical not so much, but mainly cause of the short time and learning curve! Many people in this forum said they achieved their license within 3 weeks, but I dunno if I will be so lucky cause I will only have time around July/August (hurricane and tornadoes season). I will train in the flight simulator but it's very limited cause of views, and one has to fixate in the instruments to manoeuvre, etc... thus more useful for the IR training.
The problem with flying is money/time relation. More money, more work, less time to fly... and vice versa. That's why so many prefer the full ATPL route which I will avoid cause I don't wanna stay bankrupt and dependable. There is still loads of time till summer, so I'd better start gathering the bucks, starting to study, contact the schools and then sort all those bureaucracy with VISA M1...

Florida or California sound like great places to do training... I hope they are safe in terms of neighbourhood... LOL!
