我們的I485 (NSC) 昨天 (7/24/2007) 批準 - 分享 and need your help

我的綠卡申請過程 is very similar to Waitforoptions：

1) 7/29/2004,遞LC申請(EB2 RIR),
2) 8/11/2005 (大約) LC批準 in Backlog center。

3) 2/21/2007 (大約) 同時遞I140和I485到NSC，我和老婆的and my sone 一起，其中I140是“加快”。

4) 3/1/2007 I140批準
5) 4/2/2007 (大約) 打指紋
6) 4/30/2007 (大約) EAD 寄到 (me and my wife)
7) 5/30/2007 (大約) AP 寄到(me, my wife and my son)
8) 7/24/2007 收到從USCIS來的EMAIL，關於我和 my son的I485, but my 老婆's 485 is still in pending.

Would you please help to analyze how it happens and what action I need to take for her final approval
