because getting caught and leave on your own are not the same thing, and don't have the same penalties. No reason to be rude cause you don't really know the overstay rules.
You can only extend 1 time for 30 days. It has always been like that, and haven't changed during covid.
I am not sure if BKK immigration (Chaeng Wattana) requires you to extend with 30 days first before you can change to the Covid extension.
So far the Covid extension scheme will end 29th of May. so if they want you to do the 30 days first, you will not be able to go on the Covid extension after.
