Hi all, just wanted to share my experience today at Chiang Mai Immigration for anyone curious. I was on a 30 day visa exemption stamp looking for 30 days extension.
I went at 8.30am with copy of passport main page(signed), copy of page with stamp(signed), copy of departure card and one passport photo. Of course I had all the originals and 1900 baht. I filled out the TM7 form there and had my extension by 9.15am. Just to note we did not need the TM30 even though there were quite a few notices saying we did. I'm assuming it was because we were on the exemption. It was a quick and pain free experience so hopefully the info will be of use to others. Obviously this was my own personal experience and could differ for others
