What are the procedures and timeline for obtaining a 60-day Thai family visa extension at Korat (Dan Kwian) immigration?

Korat (Dan kwian) immigration.

I rang I.O. yesterday to enquire about the 60 day extension (Thai family). The officer was helpful and friendly. She advised me to come " sooner rather than later" as all 60 day (Thai family) extensions would be valid until the 25 November, regardless of the application date. I arrived at the I.O. this morning at 9.30 and was gone by 10.30., with my 60 day (Thai family) extension valid until 25 November. This message is for people using Dan Kwian immigration, other offices may have different rules and regulations.
