After a 485 approval,
the passports are stamped at the local INS. Then, the message again changes to
Current Status:
This case has been approved. On December 05, 2002, an approval notice was mailed. If 14 days have passed and you have not received this notice, you may wish to verify or update your address. To update your address, please speak to an Immigration Information Officer during business hours.
The above message is for the plastic card itself. So, please don't get too excited about nothing and post such huge status of so many cases. INS case status online is only provided for convenience and not for misuse.
Thanks,
