urgent: received got below email after receiving green card
Hi
I got my and my wife's green card and approval notice 2 weeks back. Today I got following email. I am surprised as I got both cards and notice in my mail box. Then what was USCIS trying to deliver. Pls advise
On May 14, 2021, the Post Office returned a notice we sent you for your Form I485, APPLICATION TO REGISTER PERMANENT RESIDENCE OR ADJUST STATUS, Receipt Number lin1290343593, 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.
approval notice
During this step, USCIS initiates the background checks of the applicant/petitioner and identifies issues that may need to be addressed either during an interview or by asking the applicant/petitioner to submit additional information or documentation. USCIS reviews the applicant's/petitioner's criminal history, determines if there are national security concerns that need to be addressed, and reviews the application/petition for fraud indicators. If you have filed an I-485, I-589, I-751, N-400, I-90, I-821, I-131 or I-765, you can expect to receive an appointment notice to appear at an Application Support Center to have your fingerprints and/or photographs taken. The timing of your appointment is determined by the number of applicants ahead of you that also need a biometric appointment. We try to schedule biometric appointments as quickly as possible and in most cases you will receive your appointment notice within 30 days of submitting your application. We will send your appointment notice approximately 14 days ahead of your scheduled appointment. It is important that you keep this appointment. If absolutely necessary, you can request that your appointment be rescheduled however, please be aware that rescheduling may delay the processing of your application. Please follow the instructions on your appointment notice if you need to reschedule. Occasionally, you may receive an appointment notice to appear at an Application Support Center to have your fingerprints taken when you have filed a form other than those listed above. In these situations, you may receive your appointment notice more than 30 days after submitting your application or petition.
