I-485 RFE?

USCIS總算給我些回音了。
今天收到e-mail
Application Type: I485 , Application to Register Permanent Residence or to Adjust Status

Current Status:

On August 22, 2006, we mailed a notice requesting additional evidence or information in this case. The notice explains in detail what additional material is needed。。。

我有些問題
1。這是RFE, 或者是在要FINGER PRINT/BIOMITRICS? My Biometrics was done in May, 2005., then 2nd FP again in August, 2005, 1st FP was done in 2004.好像是FP or Biometrics該更新的時候了.
但以前收到FINGER PRINT/BIOMITRIC notice CIS從來沒給我寄過e-mail.

2.我8月18日剛寄出4th EAD and AP application( 是呀,已經是第四個了!等了N年了.)會不會和這有關?

3.大概兩個星期前,我的FBI name check還在pending(已經三年多了)
如果是I-485 RFE 會這麽快嗎?

都急死了.我的工作和同要到期了.
多謝指教
