我想提前问问，虽然我的排期未到。我和老公东西岸分居，属于不同的 filing center，如果一起file４８５，请问寄到那个center，两个人填同一地址还是两个地址？如果分开file，各自寄各自的center，请问副申请人需要主申请人copy of１４０ approve notice，marriage certificate，是不是就够了？
-Also need the 主申请人 I-485 filing receipt if separately filing. So, it is better to file these two toegther.
因为同一时间寄，主申请人没有４８５ notice。分开file，主申请人的材料里还要不要 marriage certificate？
-If the two I-485s are filed concurrently (together), send them together to the address where the 主申请人 I-485 is supposed to send. If separately, based on the living address but the 副申请人 I-485 filing has to include the 主申请人 I-485 filing receipt.
