We recently submitted an I-485 for my new wife (she came over on a K-1) and we received a Request for Evidence regarding the I-864 we filed with it. The request didn't give any details on what the problem was; it just said: "Based on the documents submitted, we could not determine that the petitioning sponsor on Form I-864, Affidavit of Support, is qualified." Is it possible to talk to these people to determine what the problem is?
I anticipated potential problems with the Affidavit of Support: I posted here before my then-fiancee's Embassy interview. They didn't even ask to see the Affidavit of Support at that time (that's standard at the Manila embassy), but now they've questioned it. My concern was that my income and assets were non-standard: the income is mostly family money which isn't taxable income for me, and the assets are entirely cryptocurrency. My taxable income for last year doesn't exceed the federal poverty level (though my real income did, and I reported that to them and explained it), but my assets are far more than enough to make up for it (~$1 million). Maybe it's just a sloppy government employee who didn't bother to look beyond my tax return (I believe I did include good evidence of my assets). Any advice on how to proceed here? I could just reiterate that I have plenty of assets, assuming they overlooked my detailed evidence at first (or I could get any job or a joint sponsor to be safe), but I wish I could talk with them and see what's up.
