Dear One Love, I am in a similar situation,but have been advised ahead of time on it. I own 3 adult care homes, which you could say is "Adult Foster Care" because the residents live in the homes. I work part time in psych for a hospital. My income is substantial, yet from the immigration standpoint, there is not enough showing on my income taxes as my gross/net income for the past few years.
Included in my documentation for both the I-129F that I sent initially, and included in my fiance's interview folder, lies a two-inch thick stack of papers. Printed on them is Title 26 of the Interenal Revenue Code, Subtitle A: Income Tax; Chapter 1: Normal taxes and surtaxes; Subchapter B: Computation of Taxable Income; Part III: Items Specifically Excluded From Gross Income; Section 131 Certain Foster Care Payments.
It goes on to explain how this income is non-taxable income, but income nonetheless....
Although I will still use a co-sponsor, I wanted to have corroboratory evidence to substantiate my case (just in case). I also included copies of every rent receipt from each resident, and copies of their checks and money orders that I made before cashing them. This process has made me become a micro-manager in many respects. Bordering on paranoia

can u paste and copy for me.. so are you getting a sponcer?? Well its not right its income i used it years ago same thing no problem but now why
Take a look at Title 26 of the Internal Revenue Code. Although this does not change the dilemma that you are currently in, it wont hurt to have a copy of it handy.
