I don't know...
if its worth it the Greek's conversion. I had a friend in my ground school at NAC. Awesome guy, unfortunately he wasnt able to finish his IR in the UK due to financial problems. He ended up going back to Greece to complete the IR there. It has been almost 6 months since he finished in Greece and he still has not been issued the license, well, he has been issued it several times, but there always been issued with it. Also and I dont know.. he said that the Greek license is only valid in Greece, supposedly they dont have a bilateral agreement with the UK.
