US Immigration from Ukraine

I am a citizen who wants to submit GC package for my parents who are currently in the USA. Some of the forms have overlapping requirements and require the same supporting documents, e.g. the main I-130 requires a passport copy and I-131 requires "A copy of an official photo identity document" which is also a passport. Do I need to treat these independently, even if I send them in a single package, and include two translated copies of the same passport? Or is it ok to include just one copy?

Rules were recently changed that foreign adoptions are now allowed in Ukraine once more. My wife and I were considering it, but frankly have no idea where to even start looking. Would we have to reach out directly to orphanages? Should we reach out to an adoption service that will reach out for us? Is there a Ukrainian government website that lists eligible children?

I would also appreciate an overview of the process if anyone can link me. My search-fu on VJ has proven futile.

My daughter in law was scheduled to get her visa in Kiev but as we know the embassy is closed. She was approved for her visa and her documents were sent to Germany. she was able to come on the refugee program, does anyone know the next step we need to take.

Do we have to wait for another letter in the mail? We got the letter a few days ago so I feel like if they mail us another appointment date I'm going to get the mail way after the next planned biometric date and miss our appointment. I feel like we got super lucky we got our last mail just in time to go today.

We have my wife's son and daughter-in-law here on a U for Ukraine travel wuthorizaton. They would like to stay here permanently. I think we need a Form I485 I130 combo. Do we need one for each person? How long does it take?
