You seem to be concerned about a very long trip from Pattaya to Cambodia, it's 3 hours 30 mins, from Pattaya to the Cambodian border with one stop, and the same coming back, I've done it myself and the driver was quite relaxed, I'm sure if you need an extra toilet stop for 5 mins you would be fine.
If you want a visa agent to assist you In Pattaya, expect to pay between ฿30k and ฿40k for the first year, it's around ฿15k for the second and years to follow. depending on if you want a multiple entry visa or not.
the first oppo I bought I had it for 3 years, I only changed it because the internal memory was getting full, the oppo I'm using now after 1 year all is okay, it has duel SIM, very large internal memory, and also a memory card slot, which a lot of phone manufacturers seem to have stopped doing, and like someone said the camera is good, they are also very reasonably priced, I don't understand people paying stupid money for iPhones.
it seems he is doing it for the first time, ฿12k to ฿15k is only for a 12 month extension, it seems to be around ฿30k for the first time, 90 day non O + 12 month extension = 15 months this is in Pattaya, assuming he is talking about a retirement visa, he doesn't actually say 🤷😂🤣😂
It's probably a best guess scenario, I suppose you only have two options, just send them copies of all the pages, and hope they understand that you only entered Thailand after the application process was complete, or send them all the pages, except the final page with your visa exempt stamp on it, and let them assume it's blank, the second option is not the most honest, but your not really doing anything wrong, nobody on here really knows, so it's your call.
There must be something going on with this DTV visa, why are they giving people a 5 year visa for one doctor's appointment, it just seems strange 😂🤣😂😎🇹🇭
It doesn't make any sense to be doing all the messing around, trying to use someone else's bank account, when you say you will need your own account in a couple of months anyway, for visa purposes, if you're doing the visa yourself, you will need to season the funds for two months anyway, an agent can assist with opening a bank account on a tourist visa.
Contact an agent in Pattaya, it is usually a lot cheaper than doing it in Bangkok, you can get the bus from Ekkamai bus station to Pattaya, and the same to go back.
