@Robert ******
all I am pointing out is that some offices (Chiang mai at least) said that the balance had to be a local Thai bank account.
Which presents many dtv holders with a problem. It also makes for an easy 'go away' response.
We can believe that demand is wrong, we can believe that Chiang mai should accept overseas account balances, but at least in that attempt, 2 or so weeks ago, that was the demand.
Anecdotally I feel local immigration offices are resistant to dtv extensions possibly more than other classes. The newness of the visa class, the fact it's an MFA project, all might be why (just guessing).
