Great News.
It seems that you no longer need a Visa for JAA training in the States. You can train on any aircraft just as long as you do not do any FAA training. IFTA is currenty offering specials to anyone that will come over and they have all the information explained.
Take a look,
THE 'INS' SPECIAL OFFER
Here is the documentation and how they did it.
I am so glad we do not need to worry about Visas.
