I havent done it myself but know a group of 6 people that do this together every time they've reset. Out and back in same day. They make an adventure out of it. They never use agents lol. All these people trying to make money on people's ignorance is a sad business.
I'm in the same boat. Applied Cambodia on the 5th, had two requests for further documentation, its been "Pending Approval" ever since. Figures there'd be tension right when I applied lol. I guess we're all in the same que to get processed. Fingers crossed this week!
So many fear-mongers in here. You'll be totally fine. Everybody that I know that has the DTV, every single one of them are just like you, went to Thailand while waiting for the approval. Zero have had an issue. Don't overthink or stress it. Just hop out and back in.
Did it just sit on "Pending Approval" until it was finally approved? I applied on June 3rd in phnom penh, still waiting as well. First they asked for proof of location (Visa stamp) then they asked for the business license for the business that I'm working for. Submitted that and the next day changed to "Pending Approval". Nothing changed since June 6th. Guessing it just needs more time.
