If you now want to split hairs to save to spare your blushes, feel free - it's hardly important.
I don't really see it as a question of splitting hairs...by any reasonable definition of 'doing' a rating (as I assume the original poster was asking) as far as I know you can't do a JAA IR in the US.
It's not a question of saving blushes either - I'd be delighted if you could tell me that you can do a JAR IR in the US (and I am welcomed to be proved incorrect)...it's just that I've thought the same question in the past, researched the possibilities and concluded that it can't be done...but please do correct me if I'm wrong...
