I sent in my outland application August 13 and they received it a few days later. I still haven't heard anything back yet and it says on the website they are working on apps received Sep 8

Its not looking good . I originally sent my app in May but they sent everything back to me in August saying I was missing a form, which I was not

they were asking for a form that was part of the inland application Package GRRRR it made me so mad because it was their fault and I had to update stuff and get to the back of the line and start all over. So I mailed everything back in August and like I said have heard nothing so far.. NOW WHAT should I be worried?
