是以费用不对的理由退回的。我们支票按旧费用写的.

Resubmission to 。NBC After Erroneous Rejection for Improper Fees Cite as "AILA InfoNet Doc. No. 07091160 (posted Sep. 11, 2007)"
NBC advises that the problem which resulted in I-485, I-765 and I-131 filings being rejected for incorrect fees (i.e., rejected for not including the new fees while the old fees were still in effect) has been fixed. If your filing was rejected for incorrect fees, please resubmit to the following address with the instructions “DO NOT OPEN IN THE MAIL ROOM” in BIG BLOCK LETTERS:
USCIS
427 S. LaSalle, 3rd Floor
Chicago, IL 60605-1029
ATT: 。Dennis Sharkey
不过不清楚以上提到的NBC是指什么，另外为什么要寄到Chicago而不是TSC呀？这个Dennis Sharkey是什么人呢？

这里也说要在一张鲜艳的纸上标上：
TTN：。CRU SUPERVISOR——CASE IMPROPERLY REJECTED FOR FEES (意思是错误退件)。
不过这里的CRU 是指什么？而且这里没说是否该寄回退件地
