Requesting permission to post this video from Integrity Legal. Seems like Benjamin Hart has a real problem with this visa (and by extension, his friend, Barry Kenyon from the Pattaya Mail), believing such things as, 1) no in-country extensions will be possible; 2) it will lead to an influx of Westerners and other foreigners that will "disrupt" the Thai way of life and 3) that it can't be used for de facto residence in Thailand. 4) That Thailand based employment would be allowed when this visa was first announced (I don't remember that claim at all).
Firstly, for 1) it's too early to say what will happen. Let's wait and see and stop with the endless back and forth speculation. For 2) that's complete nonsense; only a few thousand DTVs have been approved, that's a drop in the ocean compared to the millions of tourists that have entered Thailand since the DTV became available in mid July. Not to mention there have probably been thousands more agent assisted extensions of stay for retirement, marriage and other purposes issued in that time. 3) Why would the DTV be different to a multiple entry non-imm visa? Other than some land borders possibly insisting on a night or two outside of the country between visits (especially if you "max out" the nearly 6 month stay limit) I don't see why DTV holders won't be able to come and go as freely as multiple entry non-imm B and O holders have been so far. 4) Sounds like he's making that up or has misunderstood something.
