What is the process and experience like for a visa extension at Korat Immigration in Thailand?

Just did my visa extension at Korat Immigration. It was a (seriously) pleasant experience. Doing my TM30/90 day report took around 10 minutes in total and the officers at the desk where you get the forms at were extremely helpful - they explained exactly what documents I needed and helped annotate documents where needed. There's a quaint little print shop just across the road that does photos and document printing.

In the end I submitted (for workcation):

- Bank statements going back to January

- Pay slips (the company I work for uses JustWorks so it was basically just a spreadsheet showing when I was paid)

- A printout of the website for the company I work for (literally just hit print on the main page lol)

- An example of my work - I printed one of the newsletters I wrote for the company

- All the other forms they give you on the day (basically address/passport information over and over again)

I was asked to clarify which balances were my savings (Revolut's statements are a bit confusing) and then the officer asked me when I'm going to marry my girlfriend 555. They asked my girlfriend in Thai about some details about my work so I showed them some more examples of completed work on my phone. I think this might mean they care that I'm actually working, not only about the numbers in my bank account. Everything is legit so I wasn't worried.

I came in about 1:30 and finished at 5.
