I don't know any Turkish so I can't support or oppose your application yet.
Is there any chance you could find 10 under-merited recent English-language posts that would help your application along?
I think it is one of reason and OP applied to be a merit source in Turkish local board only.
Another reason that I apply to become a merit source is that there are not a lot of people who know English in Turkey. As a result, even if they deserve, they can't get merit from other sources.
