Some lack of real information here, SXS have just hired 6 non Turkish FOs, 2 Istanbul, 4 Antalya. There are quite a few Dutch and German FOs in the company and a few more in the pipeline. The Turkish Authority have no say or influence over the recruitment process and with the advent of SXD there was a need for Germany based FOs, they have all been recruited now.
No one pays for the type rating, this is done by the company and the applicant is bonded. Quite a few of the Turkish FOs are just waiting for the 5 years since CPL to get evaluated for upgrade, for most Turkish FOs this is their first type (738) and they have about 2000-4000 hrs on type average, good guys, know their stuff. Some would like to go to the parent company THY but this is not allowed unless they migrate to another company like Pegasus first. Ex pat Captains are increasing but the rules are changing to avoid the older guys (59+) .Having said all this, it is true the pilots in general would like to see mainly Turkish pilots recruited,
