Thanks, James. I'm on my second one year extension, and since the expiration date of the actual visa only concerns the time window to enter Thailand, I didn't think there was a limit to how many extensions one could get on the same visa.
Thanks Tod and Ellie! My covid extension is good until March 24, but I'm doing my 1-year extension at the Lak Si office (Chaeng Wattana), so I guess I'll go do it as soon as I have my bank papers in order.
, yes, I entered Thailand on a Non-O Visa, wanted to apply for a 1-year extension in January but was missing some bank papers, so they told me to get a covid extension in the meantime.
