How can I apply for a 60-day COVID extension visa after my STV expires in Thailand?

UPDATE; 19.7.22

so i went to the immigration office in Chiang Mai today hoping to get a covid 60 day visa after my 9 month STV comes to an end on 31st July.

I just took all documentation that someone said I'd need in a comment from the original post (so basically just copies of all the relevant pages of my passport and i signed these)

I got to the immigration at 12.30 and left at 16.23, I felt very relieved that quite a few people had left when it got to 16.00 as I really don't think i'd have been seen if everyone had stayed to be dealt with. It seemed to be going so so slow.

On the positive side though I received an "under consideration" stamp. The lady at the counter just told me I have to go back on August 2nd and will get a further 45 days visa. So this will be 60 days in total. The visa period starts from today rather than on the 31st July when my STV runs out, which is a bit annoying, but I did think there might be a possibility I wouldn't get a visa today and have to do a visa run to Laos, so this inconvenience is definitely the one I'd choose over the other.

So there we go, that's my experience dealing with my STV ending :-)

Hello :-)

So my STV will come to an end on 31st July and I was wondering what other people are doing who are in the same position as me?

Can we just obtain the 60 day Covid Extension Visa, I know this is only available until 25th July.

Would i be able to go to Chiang Mai Immigration today and get the 60 day extension, I'm not sure if today is a holiday or not.

I'd also like to know what types of paperwork is needed for an extension if I can get one, I believe that the special insurance that covers covid that was needed for the STV is no longer needed for the Covid Extension Visa, so that for starters is something less that's needed.

Any help or advice would be greatly appreciated.
