That's an easy one. And if I'm wrong, Agoracom will let us know.
If there is an Omani stock exchange, I would wager that OMAG is NOT on it. We're just OTC for now. Plus, the Omagine LLC is not a publicly traded company. Nope, I'd say the Omanis have to trade over here. Good thing for cables and satelites. Sending trades over by ship would get tiresome.
Now. Go out and enjoy the sunshine!
