Flew out to HCM/Vietnam Saturday, flew back Sunday morning only out of the LOS about 14 hours/overnight. TBH had no idea what to expect, all ladies on the immigration desks, did the finger print scan and photo, cursory look through passport, 2 previous 45day visa's, plus a 30 day extension, always left before due expiry, no questions, stamp, stamp and a welcome to Thailand from the lady, thank you says I and off I went, no dramas. I'm a 70 year old Brit, and the G/F future wife always says dress smartly, i.e. long trousers and long-sleeved shirt.
