US Immigration from Nigeria

I'm collating the supporting evidence for NVC at the moment. We have few events that's happened from USCIS stage to now and we'll love to include them at this stage (NVC).

Just like i labelled our proof of evidence in the packet sent to USCIS, i don't know if that is allowed by NVC. I plan to put the soft copy of our recent trip pictures into MS word, so i can inscribe the names of people in the photos, where and the day the pictures were taken, then export this into a single pdf file and upload it as additional documents. Is this allowed?

I will like to know how to properly do this additional documents which include recent boarding passes, Visa stamps, Hotel receipts, insurance certificates etc.

Thanks for you help as always.

We were documentarily qualified on April 22nd 2022. When I look in my NVC file it says a document is missing but the document is there NVC saw it and then sent a approval email. Should I reattach the doc again? We still don't have a interview date as of yet. Could this be stalling us? Please help!! I need my husband home.

My expedite request for NVC was approved today prior to being DQ. They said they would send it directly to the embassy. Will the embassy schedule my interview? How do I apply for an expedite at the embassy? Do I schedule myself and then request an emergency appointment, or email the embassy to request it? Thank you for any advice.

After my interview, I was asked to courier my passport along side a police certificate from a country I ones lived to the embassy. I m worried how long will it take for me to get my passport back and I hope there is no issue as well?

Got the 221G form to submit sponsor's 2021 tax transcript even though I had it with me. Also, we are to find a joint sponsor which we both know we do not have. However, what we do have is over $70k in savings. How do we use this rather than a joint sponsor even though a joint sponsor is what was specifically asked for.
