谢谢Pjiang老师，您贴的链接打开了。我的网上信息是这样的（收据msc开头）：
Application Type: I90, APPLICATION TO REPLACE ALIEN REGISTRATION CARD
Current Status: Finger Print Fee Deficiency Notice Sent, Case in Suspense
On July 21, 2009, a fingerprint fee deficiency notice for this case I90 APPLICATION TO REPLACE ALIEN REGISTRATION CARD was mailed to you advising you that we have not received the finger print fee, the correct amount, or a signed check or money order. The notice provided you with instructions to follow to submit the necessary payment. Please submit the required payment as soon as possible or we will not be able to resume processing of this case.
可是我收到的日期为July 21, 2009的信分明说所有费用都是零，case is accepted and now in process.只字未提欠指纹费的事情，再说我2月6号刚刚打过指模，还要重新打吗？我就不要理网上的东西吗？他要是一直给我suspense着，会不会有个有效期，过后这个case就被cancel了，我又要重新申请？就这么等着心里真是很虚。如果我还收不到绿卡的话，我就准备1月份用551的章和手中的i-90收据申请公民了，这样可行吗？会不会公民申请递上去他们再让我重新申请i-90拿绿卡的copy? 请老师指点迷津。谢谢！
