在网上看到从2004 12月部份地区EAD的申请改寄到Chicago Lockbox了，

但http://a257.g.akamaitech.net/7/257/2422/06jun20041800/edocket.access.gpo.gov/2004/04-25679.htm里又提到只有family-based才用寄到Chicago， 不过我以前emplement based用的也是(c)(9)， 真有点搞迷糊了, 有誰解释一下。 thanks
(c)(9)--Aliens filing a family-based application for
adjustment of status (Form I-485) who are presently required to file
with the USCIS local office having jurisdiction over their place of
residence;
