ما هي شروط فتح الأجنبي لمدرسة دولية في تركيا؟

If the Lebanese firm is the owner of a company/foundation authorized to open schools in Turkey, there is no issue that requires you to obtain a document in this direction from the Lebanese state.

Who gave you the information about whether there is such an issue in Turkey?

You can call me about Turkish legislation and I can give you information about what you should and should not do in Lebanon.
