Jeno Szabo i was at Phuket immigration earlier this week and asked the same question. I have a ME non O based on having a Thai wife. I am currently on the 60 day extension for visiting Thai family. I need 2 more months to season my funds before i can get my 1 year extension based on Thai family. I was told to apply for the 60 day covid extension and then to apply for the 1 year extension. They gave me the paperwork for both of these and told me it would be ok to do it this way.
