Background: My wife (USC) file petitioned for her mom and dad. USCIS approved both applications and now at NVC. My wife submitted her I-864 separate for her parents. Since me and my wife file our taxes jointly, she listed me as "household member" whose income was included as part of AOS.
Latest: NVC approved my father-in-law's (wife's dad) application but my mother-in-law's (wife's mom) application marked as missing document. They asked me to fill-out I-864 and submit AOS as "Household member". I submitted AOS documents including I-864 but they rejected again with the same message as earlier. I am totally clueless what exactly I am doing wrong here and what exactly NVC is asking us to do.
CEAC message text:
<husband's name> Form I-864A is missing. Please add <Deleted>as a Household Member in CEAC and upload all documents under their name. Please visit https://www.uscis.gov/i-864a to complete this form. FINANCIAL SPONSORSHIP RESPONSIBILITIES: Financial sponsors, joint sponsors, and applicants should be aware of responsibilities when signing an I-864 and the consequences for a sponsored immigrant's acceptance of federal means-tested public benefits. For more information visit https://nvc.state.gov/aos.
NOTE: Exact same above mentioned message was sent when I did not attach AOS documents for myself earlier and then got the same message after I submitted my I-864 AOS document.
Please help what I am doing wrong here and how can I fix this?
PS: We are making well above financial guideline to sponsor family relative.
