FYI
Trouble ahead!
I'm just reading in another place many, many people using Transferwise for there incoming international transfers have seen these transfers for June and July, including those using Bangkok Bank come in as 'Domestic Transfers'. They are now 1 and 2 months short if they are relying on this method for there extensions. Transferwise cannot help and simply say they are not responsible for your visa issues.
I myself use Transferwise as the rate is probably the best your going to get BUT I really wouldn't use them if your relying on it for your extensions.
There really is going to be a major problem ahead for some.
