@Guz *******
because it is a requirement of the PREVIOUS extension using banked money if you pulled that money out after you got the extension BUT before the 3 months was up you'd have voided the terms of your extension and the case could be made that you went on overstay effective that date :O..
That's the catch 22 switching reasons AND methods of proof of funds, you need to meet the previous extensions requirements (if it was banked money) AND the next extensions requirements if it's monthly income
