Hello to all! I arrived in Thailand on November 13th and I got the free "visa on arrival". I then got the extra 30 days and I can stay in Thailand until January 12th. Then I want to apply for the 60 days covid extension. I would like to know if I have to apply for the extension before January 12 or if I have to go to the immigration office on the 12th to apply (on some websites, it says that the 60 days extension starts on the day of the application). Also, should I always hand in a letter from the embassy, as the information available online is not consistent about this too.
Thanks in advance :)
