when you are back in Turkey why don't you apply for a Tourist Visa vs trying for a visa exempt entry back into Thailand. And even with a valid issued Tourist Visa the decision is with the Thai Immigration Officer upon arrival as to allow you to enter or not. If you have a history of staying ...living in Thailand using various methods...the risk of being questioned is greater. How about an Ed Visa to study Thai language? Or if an Ajarn seek employment with a school which will provide you with a proper work permit. Good luck and please report back your experience ...as it helps others by sharing.
