What is the process for obtaining a Non-O multiple-entry visa for marriage in Thailand via Savannakhet?

Hello group, just got back from getting my non-o multi entry for Thai marriage in Savanakhet. I Did airasia fly and ride from bangkok to Nakhon panom then Mukdahan arriving 9:30pm. I stayed at hotel MUQ which was very nice and clean right at the bus station. In the morning around 8:30am I headed to the border, left same day my visa expires no problems

50 baht for the bus ticket across the border

1,800 baht for the visa on arrival to Laos plus one photo needed

200 baht taxi to Thai embassy by 10:15.

Paperwork required:

Visa application and 2 photos

Copy of my passport main page and the Laos visa page(signed)

Copy of wife’s housebook and ID card front and back( both signed by her)

Copy of wife’s passport(not signed by accident but I I told the guy right away I forgot and he said it didn’t matter)

Copy of marriage certificate and the original to just show them (not signed)

5000baht in and out in less than 5 minutes.

Next day checked out of Avalon 2 Hotel (perfectly fine for 450baht and walking distance to embassy)

Sat at the new macchiato hotel cafe right across from embassy until 2pm, only about 10 people in line, got my passport and 200baht taxi back across the border by 15:30. 100baht to pay the immigration officer in Laos (?) and 55baht for the bus back over the river. Another 200 for the tuk tuk to Mukdahan for the fly and ride at 17:00 no problems.

Thanks for everyone’s advice on my previous posts to figure this out, I honestly can’t imagine ever bothering with the 1 year extension in country now that I can just do this over and over, it was too easy and it’s nice to get back into travel mode after the last few years.
