Deferred Action evidence

So, the closest evidence i have to show i was here on June 15, 2012 is a bank statement that shows i did a deposit on june 21, 2012. Is good enough evidence to show them?

as long as you're bank statements shows other days for before and after june 15,
i think ull be okay

I usually don't use my bank card unless its to deposit money to pay my monthly gym membership or buy online things. i have previous months showing that i use my bank card my deposits and my gym membership taking money every 25th of the month.
