One for Ubon Joe if you are around. I will extend my non immigrant over 50 visa for 12 months at Ta Yang Petchaburi very soon. I'm doing it on income. I have a letter from the overseas income provider. I have 12 months bank statements from Bangkok Bank and in addition to this a report from their Head Office showing deposits of THB65,000 every month for the last 12 months. Do I also need anything else from the bank - any kind of letter? 

You will also need the standard bank letter confirming your account and the balance on the day it was written.

Thanks very much Joe. I'm assuming that as I'm using the income method, it doesn't matter what amount of funds are in the bank account on the day the letter is written and I go to immigration?  

The balance in the account can be any amount when you apply.

Thanks Joe
