I-864 - Place of Residence / Mailing Address

[ferg9]

Hey all. Wondering if I should use the address that we intend to move to in the U.S. or my current address in China for the i-864. I know that I must establish domicile, which I've done through credit card statements, tax records, and an affidavit from my mother stating that we will be residing at her home as long as we need to once we arrive in the U.S. If I use my address in China, should I then provide a letter explaining that my domicile is established at a different address?

 

One other thing - do I need a copy of the co-sponsor's birth certificate or will a copy of her passport bio page be sufficient? Thanks!
