I extended my Retirement Visa last Friday.
During the course of the "experience" (just watching the action is always entertaining!) I was asked for my address in Thailand - despite it appearing twice on the Application Form (TM7). I produced my yellow Tabian Baan Foreigner's House Book which gives the address in Thai and confirms I have lived in the same house for the past 3 years..
In addition to the above, I was then asked for the name and phone number of a friend in my village which I read out from my phone. This was duly recorded by the IO.
I obtained the Extension with no problems.
Whether the friend request is a new additional requirement, or my inability to supply this info would potentially have caused a problem, I'll never know - but I thought you should be aware...
