Big Al.
Just to give you some background 15 FTO's in Fl have gone bust since the 11th and alot of students have canceled course so there is a bit of hassel (may be a bit strong, more manovering) going on at the moment between the ones left. If immigration really comes down hard on the M1 visa it basically means that the majority of FTO's servicing the JAR market will go bust.
My personal opinion is that Kissimmee would be a bad idea because it is inside enhanced class B air space which will cause problems when it comes to do your solo's.
As for Richard's operation (Naples) i can only say you could do a lot worse than going there. I have just spent the afternoon with Gerard one of his instructors learning to fly the twin and if the others are half as good as him you should have no problems.
But its up to yourself if you are a born bull!!!!!er and think you would have no problems bending the truth to an official you can save money by going to a none visa school. But if you want a stress free trip over pay the extra and go to a M1 school. You will usually find that if a school cuts costs in one direction that they have also cut costs in others.
If you have time send a letter to the US immigration and do as they say.
