Both my son and my I-485 have been approved lately and we received all our cards one month ago. But today I got emails ( sent at 4:15am) from USCIS alerting that "On January 8, 2008 we mailed the document to the address we have on file" with the online status as "Document mailed to applicant." What is this?
