Well,actually if you think about it,first of all you have to attend ground school and pass 14 exams,that will take at least half a year,but in the majority of cases it's closer to 1 year...So,do you really think you will be able to pass IR flight test after such a huge break in flying without any training?I doubt it.But regarding IR,I don't think it makes any difference where it has been issued,the basics still remain the same anywhere in the world...Why don't you think of staying where you are for a while?Instructing,for example?
