Hello,

So this is not DACA related but it is USCIS realted.
I have filed my I 751 ROC on March 11th, on March 22nd I have received a copy of my 18-month extension. The Original was sent to my attorney. My Attorney did not receive the original. I need the original so I can provide a proof of status to my employer. When I check the case status it says

"Notice Was Returned To USCIS Because The Post Office Could Not Deliver It
n March 28, 2019, the Post Office returned a notice we sent you for your Form I-751, Petition to Remove Conditions on Residence, Receipt Number xxxxxxxxxxxxx, because they could not deliver it. This could have a serious effect on your case. Please go to www.uscis.gov/e-request to request a copy of the notice immediately. If you move, go to www.uscis.gov/addresschange to give us your new mailing address."

Please let me know if you have seen this before and if so what did you do?
