Hi there,
I received my GC last month and since I moved after that, I decided to update my uscis address yesterday. A short time after I filed an address change request, I got a text message notification about some changes on my status. When I checked my status (expecting to see an address change request notice), I get the following message:
On August 29, 2016, the Post Office returned a notice we sent you for your Form I485, APPLICATION TO REGISTER PERMANENT RESIDENCE OR TO ADJUST STATUS, Receipt Number MSC........, 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.
I am not sure if it is just simply a glitch in their status update system because this message just popped up after I requested an address change (was expecting a change of address notice instead) and also because the address I had in the system was still valid and I received my GC through that address so I see no reason any presumptive document becomes undeliverable. Do you guys think I should do anything here? I have already requested a copy of the notice.
thanks.
