I am currently visiting Turkey on holiday and I would like to extend my stay. However, it will mean that the visa I used to come in on will have expired as it says I can only be here for a month. I arrived on Sept 14 and I am currently meant to leave on October 6. But I want to leave on October 23 or 24 depending on what the costs are to change my air ticket back to South Africa. Is it possible for me to get on the which is valid until 11 March 2020, or must I leave Turkey as I have a Schengen visa and apply for a new visa while outside the country? Your assistance is greatly appreciated.
