US Immigration from Belarus

My wife's 2 year green card expired last February and we received a 4 year extension letter. The I-751 was filed in November 2023. But not knowing when she will get her case processed and approved, I'm thinking we should file the N-400 now while waiting. We have been married for over 3 years and she never left the country and stayed in the same state since she came. Anyone has experience with this can share?

Hello, everyone! We live in GA, I'm a US citizen, my feance is already officially my spouse and she's going to apply documents for AOS(Adjustment of Status), she needs to pass a medical exam at USCIS approved doctor, I wonder if there are any program that provides free/low price insurance for her that could cover the costs of the exam and maybe some other health care needs?
Also I'd appreciate recommendations of dental insurance that could cover fully or partly a tooth extraction, implant and a crown.
Thank you for your attention and any information!

USCIS made an error on my daughter s green card. They put her birth date instead of the date when her residency started. She will be filing I-90 to get her card replaced. The USCIS website says there is no fee if it s due to their mistake, which is the case. The question is whether she can file online. The instructions on their website say the form cannot be filed online if the applicant requests a fee waiver. I m confused is this the case?

Also, if she files online, how and when does she send them her green card?

I have a question about the K1 Visa 2 year rule for meeting the fiance in theoir country. If the 2 meet; how long later do they have to submit the Visa application? Is the 2 years counted as the date the application is submitted, or the date it arrives at the embassy?

Thanks,

Does anyone know of what difference it makes if your potential fiance' has a child? If so, does the child go to the interview too? Any other difficulties? Do I file a petition just with the fiance' visa and just add the child's name and information?

Thanks,

Chris
