US Immigration from Ukraine

Hello. me and my wife(she's US citizen) currently filling out forms i-485,765,130,130a,864. It all seems easy but I'm really nervous about this no blank policy as there's not too much guidance beside don't leave it blank... there's plenty of questions that have (if any) like for example: information about prior marriages, and then there's like 15 fields with name address and so on. or representative part, interpreter. another 40? and every single field have to be N/A?.... i'm so lost and worried. I'm willing to pay if someone filed recently and can share an examples of filled forms(with deleted personal info ofc), any help would be really appreciated...

I have filed for AOS and had biometrics appointment for my wife on Aug 12. My wife has her SS #, and is 65 yrs old. Can she get Spousal Benefit social security before she is approved ?

This is a tricky question and I spoke with SS and even they could not give me a clear answer.

When I'm filling out the DS-260 should I check off my wife "doesn't have required vaccines" and then write in the notes because her doctor advised against it since she is 32 weeks pregnant? Anything else I should note there. I don't want to lie.

Not sure about other embassies doing similar, but US Embassy in Ukraine is having a virtual town hall on Sept. 2, when US citizens can ask Visa related questions. Assuming their doing this due to the lack of information and progress in regards to K1's and other non-processed visas.

My wife has a daughter older than 21 and a grandchild who is 3 yrs old ! She is divorced and I would like her to come live with us with the child as long as dad lets him come !

so what petition will I need to file ? How long do you think it will take for this process ? About how many will I have to file ?
