US Immigration from South Korea

We are trying to verify some information we found on VisaJourney.

Upon entering the US with CR1, does one still get the I-515 stamp at the airport?

Secondly, with the stamp, is the immigrant allowed to leave the states and come back _without_ the green card up to a year?

The reason we ask is that we may need to head back to the origin country(Korea) before receiving the card to tie up some loose ends.

Lastly, does the stamp still look like this?

Thank you.

For the CR1 interview, should we review answers from the I130 application? Does consulate officers normally bring up things from the application?

We are studying up questions from I-864 and DS260.

Thank you.

My wife has been in the USA for two months now and we still haven't received her SS card. I applied for it while we did the initial application and inputted the address to where I wanted it shipped. Are they behind right now? I was told it would be sent within 4 weeks.

Our I-130 was approved and we were allowed to DCF through the embassy in Seoul, SK. We just submitted/completed the D-260 online a few days ago, but we're a little confused as to the next step. There is no option to upload the i-864 documents nor pay the fees. Since I can't pay the fees, I can't schedule the interview (automated system won't let me). I heard on another post that the embassy will email me? Is this after I completed the D-260? Any advice would be greatly appreciated!

Basically wife left with her friends Sunday Sept 26th to have dinner with her them that was turning out to be an all night thing( she did this the night before as well with different friends and didn't come home until mid day Sunday the 26th) and I told her to come back home. She became defiant and hasn't come back home since. Her father and brother are also here staying with me since their arrival in June. She blocked me, her mother and father, and brother on wechat because they are part of the problem with being pressured on various things, such as trying to immigrate her brother by means of a lawyer to have him become a Christian to use the asylum clause and remain in the US. She brought her father here because he fled China due to fraud and cannot go back as he will face the court.

So she is escaping everyone due to all the pressures and had mentioned that she may do this. So I was always trying to make things easier on her and get her a psychologist to talk to as she asked for.

I have my lawyer starting a divorce but she may default on that as she doesn't want to be found.

She got a new passport from China in 2019 as her old one expired. So I do not have the info on that passport so I can look up the I-94 info to see if she left the country. The application for the 10 year greencard didn't require the passport so I need to know if there is a way to find out? I imagine I should call immigration to let them know about all this?? We gave her a week to possibly clear her mind and come back but it appears she is wanting to stay away.

I know there will be gaps in information I just entered here so I will answer questions as best as I can. Just not sure what my next step should be. First file a police report to report her missing?

With all the information I have gathered since summer, I'm possibly thinking this could turn out to be fraud. It's a long story and a rabbit hole so this is what I have for now that is relevant.
