In my experience, banks generally provide 2 or 3 statement cycles in order to achieve whatever it takes to avoid fees. That is especially true when the way to avoid the fees is a direct deposit. Changing a direct deposit does not happen instantly. Even when the issue if achieving a particular minimum or average balance, there is almost always a grace period.
I am not disagreeing with Sojo in so far as it is important to read the rules and to ask questions. In my experience, the website may say "maintain a minimum $500 balance or a direct deposit of at least $750," but rarely will they tell you that there is a grace period of 2 or 3 statement cycles. Yes, I want to see that in writing, but it is usually in a disclosure sheet the banker has, not on the website.
