回複：回複：Thanks. 回複：回複：NSC NIW-EB2_140 just approved

I submittled my RFE through overnight delivery on 02/09 and the case updated on 02/10
saying:
On February 10, 2006, we received your response to our request for evidence or information. It is taking between 150 and 180 days for us to process this kind of case. However because preliminary processing was complete, the remaining processing time will be less than the maximum stated in this message. You will receive a written decision on this case.

I don't know hom many days I need to wait.
