That's great, always good to hear of people who jump the immigration hoops successfully. Korat's a difficult office too, their 50 days-in rule is a new one on me and different from the other offices which require 15 days remaining. All the same, well done in jumping their hoops
my bad, apologies... Yes I see that you were referring to a arrival on a non-o....
Re a tourist visa or visa exemption arrival, it's worth pointing out the 15 day remaining on stamp, requirement for submitting the 90 day application and the availability of a 30 day extension etc..
