I had this problem as well. For SCB if you make a withdrawal on the day, it can show immediately show on the book, but the statement will not show it (as they update this after midnight I believe). So, the book and the statement will not match. All you need is the book updated on the same day, so that it matches the statement.
"Within 3 days of arrival" means that it must be completed sometime during the 3-day period immediately following the day of arrival. This is incorrect information. It must be completed within a 3 day period, before arrival.
Ah right. Not mentioned in the post. As Tod says, your trailing spouse extension follows your husbands. So, follow his instructions and change the reason to retirement extensions for yourself. :)
That's not what he is saying. Some banks have started freezing bank accounts until people prove they have a long term visa. Mostly in Phuket though, I believe.
Get a NON O before you leave Oz. That is the easiest way to do it. Then use your funds, that you already have in your Thai bank, to get a year extension of stay. If not, do as Tod says. ;)
