Can I please ask you sir, when you do 90-day report in person, does it have to be bang on 90th day after entered Thailand or is there any buffer? Thank you in advance.
With all respect thats not a good recommendation. Because VOA can't be used too many times, I believe max is 2 per year. So it deffers to everybodys situation. I was applying for my DTV in Penang, and was in that situation. Flights booked ahead, used already 2 VOA, everything organised and planned but visa processing took longer than anticipated. I was prepared to NOT go on the flight and just wait until I get it and buy new flight. However, I was fortunate and got the visa 2 days before my booked flight, so I was able to go on my new visa and hit a last day party too. I allowed myself 16 days to process all in Penang, and made it. If I was going again, I would probably book trip a full month, because it was tight and stressful. Hope this helps someone.
Also tried multiple times in touristy Phuket Central. I got declined every time. The staff said they were able to open before, but currently its a not allowed due to new update from Bank Of Thailand. Not sure if its true, didn't believe it.
