If he was teaching an IR, he obviously wasn't a newbie. As an ex chief flying instructor, alarm bells would ring when I see a low hour sausage factory pilot on pprune asking about Fly Dubai on one thread then instructing on another.
Oh, if someone does not know what licence he or she holds, he or she is probably unfit to exercise the privelages thereof.
To the OP, you would obviously have to do an FAA licence. I'm not sure if your 223 hours (nobody counts sim time) meets the minimum requirements? I've a feeling it is 250.
Either way, good luck to the OP. It is way better than paying to fly...
