What is the process for getting an extension of stay at the Tak Immigration Office in Mae Sot?

FYI: I returned to the Tak Immigration office in Mae Sot today (Thursday, October 8th), and I received an extension of stay stamp up until November 30th without any issues.

I had gone in previously (on September 30th) with an "under consideration" stamp and I received an extension of stay until October 26th. This extension of stay was the usual 30-day extension based on an embassy letter. (I had been on amnesty previous to that, having entered Thailand as a tourist.)

However, the new policy had not come into effect yet on September 30th, and I had to return today, about a week later to get the new November 30th stamp.

I did not have to fill out any forms, provide any photocopies, sign anything, or pay any extra fees. I simply handed over my passport, and they checked my October 26th extension of stay stamp and then inserted a new stamp dated for November 30th.

The immigration clerk also told me about the possibility of applying for the new 60-day tourist visa for after November 30th. This 60-day visa, she said, would cost 1,900 baht. She initially told me that I would need to provide an embassy letter for this new 60-day visa, but then she said that if I could not provide such a letter, I simply had to fill out a form and tick the box that says I couldn't get such a letter. She gave me a copy of this form in advance.

I was a bit confused about this, but my sense was that an embassy letter would be accepted in support of this 60-day tourist visa, but it wouldn't be absolutely required. If you could not get such a letter, you could simply fill out a form stating this and sign it and that would be acceptable. (I'll try to attach a photo of this form.)

The immigration office was completely empty. I was the only person there. And the visit was fast and efficient, and the clerks were very friendly and helpful and provided me with all the information they could. A very nice experience.
