yeah it's NOT actually, there is nothing IN writing that says that you need to have the funds in the bank during the under consideration period after you apply for the year extension.
That is an immigration office thing that some offices TELL people,
We just advise people to leave it in because of that.. BUT just for instance, last year Bangkok was having you update your bank book and bring it in when you went back for the year extension (to prove you still had the money in the account) BUT this year they stopped it and now only give a 3 week under consideration then you just show up and get the year extension stamped into your passport
