I'll need to extend my retirement visa during the next 30 days.

What are the required documents?

I already know that I have to bring:

1. My bank book (showing at least THB 800.000) and the letter fron the bank

2. Copy of my passport

3. 90 days report.

Something else?

What is the flooding situation now on Chaeng Wattanna?

I'm planning to drive there via Vipavadee Rangsit Road.

Copy of arrival card and maybe they will ask for proof of address, passport size photo.

Unless your TM.47 address report is due it is not required for extension of stay.

You need 800k in account 3 months and letter from bank and proof (account transaction that day - can do downstairs for most banks) and suspect copies of bank passbook (but do not use that so not sure). Copies of passport date page/visa/extension and departure cards. TM.7 filled out with current 4x6cm photo attached and write phone number on back (I do at top). !,900 baht and if you want to insure yourself a re-entry permit is a good idea to get on same trip. Should not be any flooding problem unless heavy rain that night/morning in that location.
