I am curious as to anyone's experience with the immigration office Chiang Rai.. Central mall?? easy ..... or difficult ?? thank you..

Hello everyone! I've done a visa extension in Phuket before, and now I will have the option to do so in Chiang Mai or in Phuket this time. Which has a better office? Phuket was very crowded and chaotic and took half a day, is Chiang Mai any better? I know it's a busy time of year, would be end of April. I have a toddler so that adds to the chaos when we have to sit in a crowded room and wait for a long time. Thank you!

Just want to say that koh samui immigration office is very pleasant. I went to get an extension today(friday) and the line to submit forms, passport, have 1 person ahead of me, so I waited maybe 50 seconds. After I submitted the paperwork (around 14:10) I looked around their were probably 25 foriengers waiting inside. Everyone left their shoes outside and were relaxing in the air con. I left to drop off my gf for work and came back maybe 15 mins later and sat down for 30 seconds before they called my number. Which makes me think that had done it faster than 15mins and they saw me come in.

Are all immigration offices outside of bangkok like this?

If it is I will try to avoid doing anything at chengwattana (bkk immigration) ever again.
