i opened a new account with the bangkok bank this year april a fixed account orange book that pays more interest than the standard saving account blue book and transfered 800000 baht from the saving account will this satify the immigration when i go for my non o 1 year extention

A cash fixed deposit is normally accepted.

Yes, but ...

I don't believe there is any official written rule saying a fixed account will be OK so doing anything other than a standard fully liquid savings account adds at least some element of risk that your office or officer will say no.

I have a fixed account with Siam City Bank and Chiang Mai Immigration only wanted to see a bank letter confirming the balance and did not even look at the bank book

I think I recall reading some reports that sometimes people HAVE had a problem with this. Again, it depends on the office, officer, and their current enforcement guidelines. I hold by my assertion that you are adding an element of risk, even if it is very small, that you wouldn't have if you hadn't done that.

Usually they are accepted but we have had the odd report of problems.

So bottom line it's your call. Is the extra income worth the small risk you will have a problem? Another messy thing to consider, suppose you have no problem with it the first time, that doesn't always mean it will always work in subsequent years at the same office.
