Contacttower is incorrect in his ill-informed assertion that IR training cannot take place outside the JAA. It is only the IR Skill Test and, common sense dictates, some acclimatisation flying that must be completed in a JAA member state.
I didn't say you couldn't do IR training ouside of JAA, of course you can, but normally when someone wants to 'do' a rating or a school offers a rating they mean complete said rating. I am certainly not ill-informed, I did my IMC rating in the US and am planning to do the FAA IR in the summer. If it really was possible to do a JAR IR in the US then I'd be off in no time...
