This is not my idea.....to get a tr and leave them in the middle of the contract!
My concern is if you get busted by the AME, or if you get depressed in Doha....and you want to terminate, what's up?
As you mentioned, they are not releasing doc's in order to apply for the tr in your certificate , so what's the reason of the bond! Of course if this is the case then they must give you all documentation in order to endorse this type in your license.
