请问8老师，公民为父母绿卡申请，同时递交130, 864，485, 765等. 请问所有表格是一起寄到Chicago Lockbox 吗？我们在加州。还是网上提交？
-You cannot file the applications online because you want to file I-130 and I-485 concurrently. Send all the documents for your father in one package and those for your mother in another package to:
USCIS Chicago Lockbox
U.S. Postal Service (USPS):
USCIS
Attn: AOS
P.O. Box 805887
Chicago, IL 60680
FedEx, UPS, and DHL deliveries:
USCIS
Attn: AOS (Box 805887)
131 S. Dearborn St., 3rd Floor
Chicago, IL 60603-5517
还请问， I-130上61.a 是填目前居住城市吗？谢谢8老师。
-Go to this link to find the USCIS Field Office in your area (put your zip code in "Field Office Locator" at the end of the webpage to identify the field office) and then, answer Question 61.a and b you mentioned:
