US Immigration from Russia

Hello, i had a interview July 22nd for my Russian fiance, K1 Visa. The interview went well and the agent said its approved. Its been 7 business days and nothing changed on ceac website it says still status ready . We emailed them, they said that the case is in Administrative Processing . Does anyone have experience with Thai US Embassy? We had all documents super ready with my lawyer. They said up to 10 business days to get passport back. Did anyone also go through this? Please help

My mom was initially scheduled her interview on June 18th this year, but we couldn't go, because it's too hot for her there in the summer, she is an elderly and not a well person. I called the embassy in Almaty, and they told me, after the scheduled date passes, I'll be able to open the scheduling page an pick my own date.
I've been trying to do that since June 18th. So far there were only 2 available dates - on July 11 and 18th. Neither of those suit us. We'd prefer September the 27th. They don't schedule it for you over the phone. I also tried to write an email to the office, which scheduled the interview initially, they are saying, they can't help and just refer me back to the scheduling page.

My concern is if there is any deadline after the case has been approved, for obtaining the interview date.
Also, does anyone have a recent experience scheduling the interview for IR-5, like we are trying to do now?
Can you give any tips to succeed?

My wife has her CR1 interview scheduled for July 19th in Thailand. We anticipate success and that she will enter the US and become a LPR a few days later. We want to file an I130 for her 19 yr old son as soon as possible. I've read (I don't remember where) that when her CR1 visa is stamped upon her entry into the US, that she becomes a LPR and can then file an I130 on behalf of her son, even before receiving her green card.

Is that correct?

I've already started the paperwork on USCIS and they are asking for her A#, USCIS Online # or her SS#. She doesn't have any of these. On the next page, the online I130 application asks when she entered the US and where, which we will fill in when she arrives.

Is it acceptable to only provide the date & location of her entry to validate her LPR and allow her to file the I130 form?

Thanks!

My fianc was wanting either a fianc interview or a tourist visa to US and she was saying she can now go to Kiev instead of all the way to Warsaw Poland . Just want to know if this is correct if Kiev embassy is accepting interviewees now or they still have everything closed ? Please advise

Has anyone managed to refuse from covid vaccination due to underlying health conditions (contraindications)? My mom is 72 yo and has autoimmune conditions. Her doctor in her home country does not recommend getting a covid vaccine because of her conditions.

The doctor wrote a letter stating those contraindication, but the office of a civil surgeon we contacted about her medical exam for a GC does not accept her doctor 's letter.
