Thank you for your advice, sir, I very appreciated. Yes, I agree with you on the differential system between the countries. But, I think those who fly in the USA will have the same flight times as much as I do once they have just completed the CPL. And I don't think it's fair for other state's license holder to get refuse to convert their license just because of the way they log their flight time in the log book. CAAT told me that they're reviewing each application on a case by case basis, which means that I still have a chance to not rocking up in a plane and spend more money and time that I'm not supposed to do. Renting a plane is probably will be my last option here. I think I will try to talk to them first. Fingers crossed!
