In 2022 I applied for Non-O >visa< at Khon Kaen (after border run).
That was on Tue, Jul 19, under consideration until Fri, Aug 12. (24 days).
On Aug 5 I did a detour to the office and politely asked.
The officer was not lazy and dug through the files and there it was!
The visa was dated Aug 2. So done after 2 weeks.
Whether or not your office is different?
