Is re-entering Thailand on a DTV visa smooth and hassle-free?

Did you apply from Hong Kong ?

And a new 180 days was issued correct?

I wouldn't expect any different. I'll be traveling to Laos, Cambodia and Vietnam soon (all on the same trip) just 2 weeks following my entry into Thailand on a DTV and I expect my re-entry will be just as smooth as on my initial entry a couple of days ago.

I've been coming and going, mostly on non-B and non-O multiple entry visas for years (also had some non-B and non-O extensions of stay with multi re-entry permits) and these were also smooth.

Only one time was I hassled at the Ranong border and asked to supply proof of K in cash BEFORE leaving for Myanmar. They also talked about a plane ticket and accommodation booking but I explained I live in a house and I don't have any bookings for when I return from Myanmar (the plan being to spend a night in Hua Hin before getting back to where i reside). However, I only made that booking the night before arriving there. Also, while I coincidentally happened to have a booking for a flight to Europe 6 weeks later, I talked my way out of that too. Besides, I have been living in Thailand for years and while I travel back home around once a year, I don't generally have proof of outbound travel with me. Most of the time, unless I'm heading to Europe, America, Australia, Japan etc. then I'm going overland (for instance, if heading to neighboring countries or even China etc.)

In the end, they gave up after I explained I had a non-O multiple entry visa AND I was heading to Myanmar for several days not just a simple border run.

I had almost 20K in cash with me, because this was needed to pay for my hotel stay and one day trip, as well as other expenses on that trip for me and my family. Credit cards aren't accepted anywhere in Kawthaung and while there are 2 working ATMs in town, they use a poor exchange rate.

What was your DTV issued for?
