After applying for the non 0 extension about 1 week ago, I received a call to bring a "witness" /close neighbor for interview. I think this must be the home check that other posters speak of. The officers were very polite and questioned my neighbor for about 15 minutes. My wife and I waited and chatted informally with a higher ranking officer. This took place in the rearmost building and without going through the queue. After my neighbor left, my wife and I signed some more copies of passports/ pages and her Thai id card and they said "welcome to Thailand". I still report back after 30 days( I assume to receive my 1 year visa stamp). Everyone was polite and helpful.

I had that on my first extension

Yes after 30 days you will receive the one year extension of stay stamp if ready - but do not be alarmed if a bit more time is required as there have been a lot of delays this year.
