回複：回複：My AP came just two days after receiving that email.

Check your I-140 status on line. It is the most accurate info. An approval notice for I-140 should be sound and clear, something like this " This case has been approved. On XX,XX,XXXX....."

It seems that if your are applying for a card, e.g., EAD/AP/GC, sometimes the approval notice will say "On XX,XX,XXXX, the document we made based on the approval or registration of this case was mailed directly to the person to whom issued."

Good luck and stay cool.
