I am an American in Thailand currently on a 45 day visa exempt stay and would like to extend my stay. I am seeing a lot of conflicting information. First, where do I need to go for this? I have seen references to Muong Thong Thani (Counter K) and also Chaeng Watthana. Which is the correct location? Also, I have seen one site say the extension is for another 45 days and some saying it is 30 days? Also, what papers do I need? I have seen that I need a passport photo and 1900 THB. Do I also need new COVID-19 insurance paperwork to cover either the 30 or 45 (which one?) days for the stay? My stamp ends in 9 days. Thank you for any information you can provide.
