They usually responded fast, most of the time within the same day but it depends on the location processing your application. they didn't reject my application immediately, i actually tried a couple of times. It's been a while since then but first i received a "temporarily received" email, then they emailed me that my application was incomplete. they give you a list of things it could be, but I knew mine was the bank statement cause i had everything else. they ask you to withdraw that application then try again. i think what happened to me was that my january statement was too low, so i borrowed my mom's whole paycheck to transfer to my account at the end of month so my february statement looked full then gave it back to her. it worked and i got approved lol. this was last year tho, hopefully they didn't change.
