"Theoretically" you should be able to finish in Germany, it's a JAR country since May 1... that's what the European harmonisierung is all about , right?? The German authorities are supposed to have exams available in English, but they are so busy with getting the normal day-to-day business done, they may not have some yet.
I know of a case, where someone started out in Switzerland, moved to Holland because of business and wanted to contiunue there, the Dutch wouldn't accept his previous training.... huh??
Usually the medicals, flight hours, etc. will be accepted. And if you finished the written while still in England, then the rest
should be no problem. The best thing is to contact the local authority for the area you'll be in. Send me a mail... maybe I can find out more for you.
