All right, so my husband and I are living together here in Australia, and I'm filling out the I-864 (which I did not realize I needed to fill out as well as my father) and it wants me to prove domicile in the U.S.? I don't get it. I definitely do not have domicile over there, unless you count my dad's place, where we will be staying until my husband gets a job. So would my dad's address in the U.S. be my domicile and my address here be my residence?

Edit: I just read the info on the Sydney Consulate site about it plus info in another thread, in which kaffy said this:

My husband has been living outside of the US for the last 4 years and will be proving his domicile with:
US bank accounts
US permanent mailing address (his parent's house)
Current washington state driver's license
Grad school acceptance letter
Lease on a new apartment
Arrangements to relinquish residence abroad (selling our car, one way plane ticket, etc)

All right, so can I set up a bank account from over here and use that as proof?
How do we prove that my dad's house is a permanent mailing address?
I have a current VA driver's license.
We will have one-way tickets BUT we aren't going to buy them until we have the green card.

And this was also on the Consulate site:

If the sponsor establishes U.S. domicile, it is not necessary for the sponsor to go to the United States before the sponsored family members. However, the sponsored immigrant may not enter the United States before the sponsor returns to the United States to live. The sponsored immigrant must travel with the sponsor or after the sponsor has entered the United States.

Does this mean my husband and I will have to be separated and make this trip separately, because that really distresses me.

Help?!
