US Immigration from Egypt

My husband received the dreaded yellow paper at the interview im Egypt today. Terrible experience. First, they argued with him about ourdate of marriage. He told them the correct date 3 times and the officer said it wasn't correct. Like, it's on the marriage certificate Then he was saying it's not right our relationship began while I was legally separated from my ex husband (we were married a year and a half after). They only focused on my previous marriages and not much else. Then they said they need us to upload more proof. If anyone can give me an idea as to what else to upload I would appreciate it. Here is was I already uploaded:

Both previous lease and current lease with both our names, about 200 photos with us and friends/family over the past 3 years, chat logs from the very beginning with us, me and his mother, sister and father and him with my mother, affidavits from my mother and his parents, proof from the 6 trips I've taken (I'm in Egypt now, was hoping he could fly back with me) proof of contacting the congressman and Whitehouse for assistance, shared bank account.

We've never emailed each other because we communicate via messenger. And phone bill? We call via messenger so there are no charges.

I'm just not sure what else I have to upload

I want to ask about filling th DS160

Regarding other names.

I have three old passports the first was having some different I. Alphabets or single letter for example : Moustafa and old passports mentioned Moutafa or Kassem and old passport mentioned Kassim.

My question is that small change is considered other names even the original passport language mentioned the same names in all passport but the changes only in some letters in the English names ?

I'm a J-1 visa holder and it will be finished on june-2023

A restaurant owner offer me to be my sponsor but I'll do all the process and he will provide all documents and signatures needed.

Is that can be done and how I can start??

Hi my beneficiary doesn t have a passport and never had one. I know it asks for a passport number on the application. I was told you can use a birth certificate instead. Is this true?

Is there any issue with a petitioner changing employers while form I-130 is pending?
