Read this web site and you find out!!! Almost everything you want to ask is answered on this website.You are unable to get a JAA IR in the States. You can do ATPL theory, MER,CPL, FAA I/R but not JAA I/R. Also you need to an I/R conversion and a MCC course at Cabair or a similar school to have a full Frozen JAA ATPL.Regards Scott
