Until today ,i finally figured out why we got a RFE
our REF on AUG.9.It actually didn't request us any futher evidence,they mailed that RFE to us because of this
Public Notice made in 2006.I hope this might help some people if they also got a same RFE like ours,as i knew one other people also got this,anyway i am happy i know the answer to that so-call RFE.This bugged me for a while.Good luck wtih your NOA2 guys:)
