I-130 批准了，下面还有什么材料需要？我们想尽早准备。请帮忙！

XiaoBaiTu or any expert here, can you please list the documents
that will be needed after you receive the approval
letter from CIS?

I know I was told that CIS would let people know
step-by-step. We just want to prepare in ahead for any
needed documents that is not required in a time-limit.

Also, for parent's address in China, do you list home
address or mailing address? I think only home address are asked.

Thank you so much for help!
