m.o.

I agree. I believe you sent more than required. I just submitted my husband's N-400 application as well and we haven't received confirmation yet. It  showed that they received his application on January 3rd but the check was not cashed yet and no email or text notification yet. You'll be all right. If they sent you an RFE, then just provide the necessary document. Simple as that. 

My NOA 1 is dated April 03 and still haven't received an appointment letter yet!! I made a service request via phone 2 months ago and infopass last week,, they said that they are way behind in processing the cases and I have not been scheduled for an appointment yet. they told me to check back If I don't hear from them by October... CAN you imagine !!!!!

Call them to check for sure because we sent our petition toward the end of June and got our NOA1 on June 25 and we had an appointment date for July 21st. But of course we NEVER GOT THE NOTICE because it turned out it was sent to the wrong address (to my next door neighbor) and my irresponsible neighbor didn't go through her stack of mail for apparently two weeks! She finally came over to my doorstep on Friday July 24 with the letter. So we missed our biometric appointment!

When i call USCIS.. I tell them i have received my approval notice through email but not the hardcopy. People call it NOA2 here because that's usually the second notice of action you receive. Simple as that.
