We sent my husband's I-751 on July 6th (his gc expires on 9.29.06) and the check went through on the 12th, but as of today (Sept. 10) we have yet to receive anything. No notice...nothing. We did move in May, but I sent in AR-11 to local office as well as NSC. The only problem I can think of is that my check had our old address on it. Also, I got a copy of the cleared check from the bank and there was an LINXXXXXXX number under the endorsement lines. I tried entering that on the usics.gov tracker, but it said that it wasn't registered. I was just wondering if anyone had a similar experience or if anyone has heard from the NSC or loacal office yet? Thanks in advance.
