absolutely ridiculous requirements. The govt here should clarify this immediately. I'm on a different visa, but was thinking of changing to a DTV in the future.
Most comfortable way is to fly from DMK or BKK to Phnom Penh or HCMC and back in a day. I guess the cheapest return tickets are going to be around 3000-4000 baht just for the flight.
It's not that easy to get to grips with all the minutiae of visa bureaucracy. I'm not a visa expert but I understand the difference between a visa and an immigration stamp.
