That's correct. Then the following paragraph says:
"You may also choose to submit IRS Form 1040 or 1040EZ, however, those documents do not serve as proof of income. In order to demonstrate sufficient income to meet the HHS guidelines, you must submit either an IRS Tax Return Transcript (which covers all needs for income verification purposes), or IRS Form W2s."
And that is why I find it confusing. Why submit it if it serves no purpose?
I'm aware of it. However, this is something that is required when submitting I-864, no? To make this a bit more confusing, what's the point of proving past income, which was earned outside of US? Petitioner has now moved back to USA where they have started a new job (hence the reasoning for the DCF application)...
