Going through process at moment. Best bet is go to Tessaban and ask as it's a complete mare. You might have various tessabans within you're area dealing with different sub districts, and I would put money on it that they're not doing the same as each other, seriously.
you're welcome. Good luck. Just bear in mind mate when dealing with any government agencies here, even with 2 same in one city, for instance, tessabans, to get the same answer from the 2 is about as rare as rocking horse shit.
"in almost all offices", that's got the potentially to bite someone on the arse when applying mate. I fairly sure the rules are as I said. However, as we all know things are not consistent throughout any government agency. Another example is the application for yellow book, what an absolute pain in the hoop.
just as a thought, it may be worth getting a multi entry permit. It may save money in the long run if you get invited to more meetings out of country in the coming year.
If you already have 800k in bank, as long as its been in the account for 3 months for 2st time visa or 2 months, then do it yourself. Unless you are trying to convert from a tourist type Visa
