Arrival post,
Got approved for the DTV visa two months ago, arrived a month later than my original intended arrival date. Immigration officer seemed happy that I had a visa, and said that most people aren’t getting appropriate visas at the moment. (I believe people have to apply for a visa exemption on arrival pre departure now, but a lot of people aren’t) stamped me in and said after 180 days to leave Thailand, and then come back for a new stamp. Whole process took 2-3 minutes, didn’t ask for any documentation etc. just had a print out of my visa. 🙂
