Questions Regarding Household Member Income

[JJ1008 1]

Hi, I wanted to see if anyone can clarify some questions I have about the NVC/Consular stage for a marriage based visa.

My husband is my sponsor and we filed the I-130 which was approved in May 2022, it was then forwarded to the NVC and we submitted all of the required documents in June. When we submitted our I-864 paperwork, my husband was employed and his annual income covered the threshold needed to sponsor me, but he has since lost his job, and due to some personal things going on in his life, he may not be able to find another job before the interview. His income has been cut off, so now he will not make enough this year to sponsor me on his own. His mother lives at the same residence as him and we saw that you can combine a household member's income so that together it covers the threshold. What I'm wondering is can I bring an updated I-864 and I-864a plus all the required docs for both of them to the interview and can they make a decision on the spot based off that, or will they require me to wait to process it further, and will I have to do another interview because our situation has changed? Also wondering if it is acceptable that my husband will be unemployed by the time I get to my interview. Is he required to be employed even if he is combining his current income with his mom's? Thanks for your help!
