US Immigration from Nigeria

My husband has his interview on February 09, 2021. When we uploaded everything at NVC, last year my sister was going to be a joint sponsor.

My daughter lives with me and we have decided that she will be doing a i-864a. So we corrected everything and sent it to my husband.

My husband was asked who was xxx, he said that was my sister. He didn't even tell them that we wanted to use my daughter who is living with me.

So on the paper that they checked it is asking for the joint sponsor's 2019 tax transcript and w2. How do I get in touch with the embassy in Lagos and let them know that we want to use my daughter and that we have signed a contract?

My sister doesn't pay taxes, nor do she has a w2. This is not the reason for us doing this. My daughter's income is pretty good and she volunteered after the fact. Thank you so much in advance.

P:S due to a boating accident a few years ago my husband Studdard a lot as well as he is anxious...

Do we email the embassy and ask that she be added? Or just drop it off at DHL??

My Nigerian Spouse just received his visa but no packet or none of his info was returned?! I m reading he will need to present the sealed packet that should have been given to him when he goes through customs, is this normal for him to not receive this? Will he still be able to come? Help!

I submitted all the required documents at NVC they checked and accepted everything but they said i should get a joint sponsor. My questions is can i still be scheduled for an interview even if i dont provide it at NVC stage. I was thinking i should just take it along to the interview.
