Are there any other alternatives to buying a property in Turkey in order to get the Turkish Citizenship?

Yes. You are allowed to get the Turkish Citizenship if you deposit 500,000 USD at the bank provided that this amount remains there for three years and is determined by the Banking Regulation and Supervision agency. If you employ 50 Turkish people and get a validation from the Ministry of Labor and Social Security. Or if you make a fixed Capital investment of 500,000 USD declared by the Ministry of Industry and Technology.
