Hello. I am going down the I-130 line and recieved my packet 3 on Friday, and have all the documents required but we are confused as to how to fill in the I-864. My wife (USC) has been living and working here in the UK since we got married in 1998, she has e mailed her old company saying that she will be relocating sometime in the autumn and will be looking for employment (she had a good job with the cable company when she left) and got a automated reply. What are our options considering nothing is certain till I get the visa? Any help would be greatly appreciated. Doug & Kim Phillips
So I'm taking from your post that it is unlikely that your wife will get a firm offer of employment before your interview.
From what I have researched - and we are now at the I-864 stage of this process too (and we both live in Canada), you have three income options. Either you can prove:
1. That you have income that will continue when you arrive in the U.S. (doesn't seem like this is the case for you?)
2. You can use assets equal to 3 x the poverty level or
3. You will need a co-sponsor.
As far as 'domicile' is concerned, I'm not sure how the consulate(s) in the U.K. view this, I think it is open to interpretation. I did ask one Canadian who has recently been approved. In his case he stated his country of domicile was Canada and then added a letter from his (U.S. Citizen) wife that they would be entering the United States together.
I also think that if you post on the U.K. board you might get some help from those in your area who have experienced this and find out how they handled it.
Best of luck to you!
