What is the process for extending a 90-day Non-O visa to one year based on marriage to a Thai national in Samut Prakan?

Information only:-

Samut Prakan immigration, Extension of 90 day Non O to one year based on marriage to a Thai national using banked funds.

Started the morning trip to ATM to update bank book, I had prepared the proof of funds earlier that week.

We arrived at Immigration had my Online TM-30 screenshot certified.

I was then advised to fill out new documentation (the font has changed from those we used previously and the notice of the charge being 1900thb had been removed)apart from that identical.

Despite the Immigrations office paperwork stating Marriage cert (Kor Ro 2) dated that year is acceptable, they actually require it dated that day. So we took trip to Amphur over the road to get another certified. There is no signage however we found you do not have to que for this service and can go straight to counter 10 to get it.

Back to Immigration office, submitted paperwork all was now in order.

Again it not detailed within the Immigration offices paperwork was that we required a Thai National to witness for us, they kindly gave us time to find one.

We were advised by the IO to leave at least 400K in the bank until the extension is approved next month. Also that we will get a phone call to arrange a home visit in a week or so where they will take identical photos to those we already provided.

A photo of both the wife and I was then taken there before my passport handed back.

Pleasantries were then exchanged, Job done!
