So that why I pasted here http://web.wenxuecity.com/BBSView.php?SubID=immigration&MsgID=197789
A couple of friends of mine they submitted together with me at the end of last Sept. The same situation as yours and mine, they got approved two weeks ago, so I am a little anxious about the status of my I-140, just like you. But I hope it will be approved soon.
Good luck.
