ya i was reading something somewhere about you need to show all your deposits i mean cant i just have the bank write a letter that says I have such balance in my account i mean wouldnt that work or do i still need to show each month statement?
There are people who have brought a "few" recent bank statements and others who have brought a year's worth. In reality, you don't need to submit ANY regular monthly statements for your account. As a previous poster pointed out, the instructions are specific about the statement from the bank as being one that lists current balance as well as total deposits over the past 12 months (not last year). They are looking for you to request this specific letter from the bank, not submit the equivalent bank monthly statements. My bank charged me $30 for it. Thanks, BankOfAmerica, for taking good care of my money.
Its generally felt that the letter provides a rough cross check for the income and assets statements that you make on the Affidavit of Support. If you tell them you've got megabucks in assets and its not reflected in the current balance of the bank statement ("Ohhhhh, its in my other account") then you're running a risk. If you tell them you make Megabucks of income and your bank statement shows paltry deposits, then you'd better have a shiny clean employment letter or your risking some serious questions or an RFE.
Obviously, the numbers don't have to exactly match anything, but the total picture from all evidence needs to convey the impression that you can afford to support having a spouse and/or family (especially above the poverty limits).
