Can you extend a tourist visa at the Lamphun immigration office after staying one night there?

Background: Anyone who has spent time in the ‘Rose of the North’ probably knows Chiang Mai immigration is notorious for being extremely busy with hundreds of people queuing per day starting before sunrise.

Lamphun office is tiny and barely sees anyone.

Question: if someone stays one night in Lamphun and gets the property to file a TM30, can you use the Lamphun office for an extension on a tourist visa or visa exempt entry?

It’s a 30 minute drive and rooms from 300฿. Why not have an overnight holiday to save spending 8-12 hours at immigration?

I’ve convinced my friends to try this so they don’t lose a day of their holiday.

Am I wrong? If so, the group will tell me quickly.
