Hi, I am currently in Chiang Mai and I have an education visa from Bangkok that I would need to extend before September 8th. However, as it's not possible to travel to Bangkok and my course is online, can I extend it in Chiang Mai? If not, can I cancel the education visa in Chiang Mai (the school is willing to email the letter) and get a 'covid extension' while I wait to go back to Bangkok. If I can't 'cancel' the ED visa, can I do a covid extension and then go to CW when I return to BKK in a few weeks? Thank you very much.
