Hey I read a post from you in another topic on this website, you said you didnt send in passport photos in your renewal packet well.... you were suppose to send in 2 passport photos (name and A# in the back of each photo), you are likely to get a RFE issued to you for no passport photos, it happened to my friend when he renewed his I-821D/I-765. it will take them probably more than the estimated time frame for renewal to generate a RFE for you, expect a delay to your case.
