US Immigration from South Korea

Been having thoughts about my options and have read some mixed responses. My wife has her 2 year greencard, and we have filed for the I-751 back in Nov of 2019, and she did her biometrics a few weeks ago. She has changed her priorities a lot since coming back from China back in June of this year because her father is in legal trouble. There is a lot of other stuff going on that has made me rethink what this marriage was intended for, which was to start a family since I had waited til my mid 40s to finally get married. And there are other issues going on that lead me to believe that she is changing her mind on a lot of things in our marriage.

I can still remove an I-864 as long as there has not been an interview or 10 year green card issued? I'm just weighing my options and thoughts before I act as this is a huge decision.

I needed to make sure laws didnt change as I saw something regarding new changes for immigrants passed this past April. So the wife still has to be a USC and I as her husband, a US citizen, cannot apply for them as well? Is the new change that she as an LPR can now file for him instead of waiting to become a US Citizen?

We sent in stocks and bank statements as part of sponsor's I-864 back May to NVC. So the additional asset portion of the I-864 form matches May's financial statements.

Hello, July 2020 flier here. My wife just completed her biometrics last month. I checked her cases statuses for her EAD and AP today, and it finally says both were approved and that notices were sent out. Does anyone how long it will take for her actual EAD card to be processed and mailed out from the date of approval (9/14/21)?

I Filed first week of February 2021 biometrics in August 26. Yet nothing . No update online. I guess the processing just started. What to expect Next? How long do I have to weight again?
