Request for Initial Evidence for I-864A

[ecegrad 0]

I received a yellow color letter for Request for Initial Evidence yesterday. It says my I-485 application cannot be processed and I cannot get interim EAD until 90 days after I send requested items. My father-in-law is my I-864A household member whose income is added for my sponsorship. The letter asked the following items:

- Proof that household member was employed in US legally: This is fine, I can send his green card copy.

- Letter of Employment and 6 months pay stubs: Here is the problem. I will tell below.

- I-693 Form: How this is an initial evidence? And how can this hold my EAD?

- Supplement to I-693 Form: Again, how can this hold my EAD?

My wife is pregnant and we are expecting a baby soon (within few days). Now I calculated my father in laws last 6 months pay stubs. Unfortunately, with his pay stubs our household income requirements won't meet (It did for last years tax file, but this year his income is little low). And add a new baby, we will be way below poverty line (if USCIS later inquiries again).

I want add a new joint sponsor (I-864) and remove my father in law (I-864A). Will this harm my AOS process? What should I send with reply? The mail says I can add a joint sponsor. But won’t they ask why I didn’t send my father-in-law's employment letter and pay stubs? Can I send both his information and new joint sponsor's information?

Any help is greatly appreciated.
