If you have JAA CPL, go to some USA school and convert your licence to FAA commercial (or you can get FAA PPL which is granded in your JAA license- contact FAA). Then you can go to get FAA IR. (Check that school has TSA approvals for foreign students. You need to have that). After that go back to Europe and try to get added trainings to have JAA IR with all theories. (examble in Proflight, Sweden). Whole this might take about 8 -12 month, if you are lucky and work hart. Still it might be cheaper than have JAA IR straight in Europe. Its about you. You can do JAA IR theory first in Europe and then go to USA to do flight part.
Note: Confirm everything from US school, before start. Be aware what they promise in the phone!
