if you want to chance it..download the form and do as much of it as you can yourself..pull it out if asked..and , at least they will know you have tried..suggest you just play innocent , and only briefly describe the difficulty, and sort of indicate that is not intended to get the landlord in trouble..go gently.
thanx....and will post if there are any changes re Chiang Khong (for my situation , at least). I've only heard about the the COVID stuff (np in my case)..AND the need to get transit papers before Thai exit (ones Thais get to cross) , and for non thais ..supposedly a charge .....used to be my normal exit bounce pre COVID so I think I shall stick with Chiang Khong/Huaixai , since it went smoothly 2 months ago.
Good suggestion...but having done the Chiang Khong trip last time, and rather like the trip itself (live in Chiang Rai, and hire a car) ..going up one way and come down another (following the River Kok, with many great riverside stops to eat) ..last trip was on a Sunday, and at least that particular time , afforded a very fast and friendly border experience...
