normally you and your hu*****andshould receive two letters each after 485 is approved, an approval notice and a card. Approval notice usually goes to your laywers, and you may get a copy.
One meesage series after 485 approved is
1. "this case has been approved"
2. "Card is ordered"
3. "Card is mailed"
The turn of message appears to be very quick. Sometimes, some of them may be missing.
