Not to hijack the discussion, but I'm in a similar situation. I am the USC petitioner; my foreign wife is the beneficiary. The majority of my income at present is foreign and will cease when we move to the USA. Meanwhile, my US income only consists of dividends and capital gains (do capital gains even count? they are included in total income on the 1099...) from investments and isn't enough to reach the threshold. My father, whose annual income is over the threshold, will be joint sponsor (and thanks to pushbrk's comment, I know my mother should also fill out an I-864A). I have assets that are enough to pass the 3x formula, but I have read in many places that it's better to find a joint sponsor than rely on assets for this application.
My questions are, first, how do I report my individual annual income on part 6 item 7 of the I-864? Should I enter the income from my investments from the most recent tax year only? Does entering the value including my foreign income suggest in any way that I am an able earner, or anything like that? Second, is there any point in reporting my assets, if I intend to use a joint sponsor anyway?
Thanks!
