I'm going to go do my COVID extension tomorrow. My TR visa 30-days extension ends on 16 May. It's my first time.
1) But I heard that some letter from the embassy is required... What is it? What package of documents is required in general?
2) Where is the address for COVID extension?
3) Do I need to pre-register online?
Thank you very much. Maybe the questions are simple, but for me this is all the first time
