Ok, you'll need to do a fair bit of research on this site.
Firstly, can you work in North America? If not, then you'll have to convert your FAA or Canadian licence to a JAA/EASA one.
Yes, there are some JAA/EASA qualified schools that operate in the US.
How will you fund this? Do you plan to go modular or full time?
Have you researched the "what if?" post training?
Good luck.
I don't know the IAA's requirements but a good feel for what's required for the UK CAA can be found by downloading "LASORs" from the CAA's site.
