My current status has not changed from the date they recieved my file and sent me the NOA.
I sent the application 10 days after 4 years and 9 months.
Not sure how USCIS does this, but some posts the forum referred to this being simply a computer generated letter, which I doubt since my date has been highlighted with yellow!
Good for you regarding not finding anything there. I hope it does not happen to anybody!
I did read a similar post (maybe the same) although I cannot find it now. If you find it send the link to this thread.
Thanks.
