Can you still get an non immigrant extension using only the 800,000 in a Thai bank, or do you now have to have the 800,000 AND 65k monthly income. 

AND /OR

Unless your embassy can provide "income letter" you would use 800k in bank account method.

So it's not AND it's OR.

Which country is your passport 

 

Edit: OP, seems from other threads you have UK pp.

You will use money in bank method.

For extension retirement you require 800k in Thai bank account in your name only seasoned 2 months prior to application for extension and 3 months after application not below 800k.

In other months can be as low as 400k
