Can I apply for a 60-day COVID extension in Thailand after receiving a 30-day extension?

ahhh, that makes sense, you hadn't gotten the "regular" 30 day tourist visa extension you can get from it so they sold that to you instead. (y) Go around the 26th of Nov and apply for a 60 day covid extension

I sure wouldn't use the Samut Prakan Immigration office (even if it means getting a hotel in bangkok one night so you can use Chaengwattana) That samut prakan office is hard core on covid extensions and I'd rather have a tooth pulled than go there to get a covid extension.

Check what is written with your stamp.

If you entered Thailand on tourist status and didn't apply for a 30days tourism extension yet, your extension could be that tourism one.

If it's a tourism extension, you could apply for a Covid extension on or before 26th Nov.

If it's under consideration, you cannot. You go back to the immigration office to get the stamp for the rest days.

Go to your passport and see what the stamp says. If I’m a betting man, I would guess it says “under consideration “.
