EAD Renewal - I-485 Receipt Notice lost

[sahilsakhuja]

Hello Forum members, My EAD/AP card is expiring on Apr-13 and I filed for the renewal for me/wife on Jan 31st and we got the receipt notices on Feb 4th. One problem is that i have lost my I-797 Receipt notice for I-485 so i could not add that supporting document on my file. I called USCIS customer care before sending the renewal application and they sent me mails saying that since the Lockbox has delivered the notice, we cannot do anything about it. I am hoping my EAD/AP renewal should be OK but i would like to know if i can get a duplicate copy of my I-485 receipt notice somehow. I do have I-485 receipt receipt for my wife. Please advice.

Regards,

Sahil Sakhuja
