請問8老師，公民為父母綠卡申請，同時遞交130, 864，485, 765等. 請問所有表格是一起寄到Chicago Lockbox 嗎？我們在加州。還是網上提交？
-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
還請問， I-130上61.a 是填目前居住城市嗎？謝謝8老師。
