Just back from a visit to Jomtien Immigration for my 90 day reporting.
Walked in at about 11.30 and was able to go straight to the reception table to get docs checked. Then to get a Queue number. By the time I found the desk where I had to go and sat down, my number came up. 2 minutes looking at the Immigration clerk and my passport was handed back with the slip showing the next reporting date.
5 minutes in all and I was out. That's service.
