US Immigration from Ukraine

Hi! I am trying to find out how to schedule the interview in Kyiv for CR1/IR1 visa, but I do not see that option. Could you please advise what visa category should be selected:

My parent received his visa with annotation on it "212 (G) (2) (B) Class A or B (TB) Req Attn of USPHS At POE". He was suspected to have Tb and had to do the sputum culture, which took 8 weeks.

1. What does this mean for us? Do we have to be worried?

2. I don't think he has latent Tb, but just in case he has to receive treatment for latent Tb at USPHS, would that be free of charge?

Any recent input of how long it takes to get a visa issued after 221G administrative processing for the medical exam (or anything else) in Kiev, Ukraine?

Is there any possibility Ukraine will be added to the Visa waiver program?

or that there will be expedited tourist visas for non-resident spouses while our CR-1s slowly progress?

i will try to make the story short. My wife and my stepdaughter had interview in march 2021 and were put on administrative processing. In December she got a call from embassy that background check was received and they can proceed with their visas. My wife and stepdaughter were asked to do new medical exams since the previous ones expired. on january 5th we checked the status of their visas and my stepdaughter visa was issued, but my wife received a letter from embassy stating her visa was refused under section 212 a 9 a and there is waiver available for her. I forgot to mention she was in expedited removal and removed from the USA on September 2018. the thing is my stepdaughter visa is valid until June 22nd 2022 and I'm not sure if we get waiver approved before that date. I will not be able to take care of my daughter without my wife being with her. What are my options?? can my daughters visa be extended ?? can we expedite i-212?? When I check processing time for i-212 form, it doesn't look good. It says , it take 6-8 months to get it approved. By the time that waiver is approved my daughter's visa will expire. I hope someone here can help me and tell me what my options are.
