AS in every JAA/EASA certified school in the US will have you do your IR back in Europe, there is no other way.
To specify further - only the test must be done in EASA airpsace.
All the training can be done in the USA - and then most schools provide some training in Europe as well. There is no requirement other than the test to be done in Europe.
There are 2 schools in Florida with IR approval - only one activily uses their approval though.
