Thanks for these replies. Just to clarify exactly what my problem is, I am being told I need to provide bank statements for the past 12 months. Previously, only 6 months statements were needed. Bangkok Bank were able to produce these on demand on the day of application, so I would go to the bank first, update my bankbook etc. and leave with everything I and Immigration needed. Now however it will not be possible to obtain the full 12 months statements on the day of application. I will be able to request the first 6 months of the year statements to be mailed to me, but I am seeking clarification as to whether or not Immigration will understand and accept this. I am not sure how long this 12 month requirement has been in place, but if anyone has already experienced this, I would greatly appreciate an update.
