Hello everyone!
I've been following this thread for a while and decided to post progress for my parents' IR-5 visas:
I've requested case transfers from Moscow to Warsaw on 08/11/2021 (DQ since March 2021). On 09/07/2021 the request was approved and on 09/09/2021 we got new WRW case numbers. On 10/14/2021 we got interview notices for 11/04/2021. Unfortunately, they won't be able to make it since my sister is due to have her first baby around that time and they don't want any additional stress for her or them during that time. I've emailed Warsaw embassy the same day we got the interview notice but they still haven't responded so I called a few days ago and they told me I can only reschedule if they miss their interview. So that is what we're planning on doing.
Hopefully we'll be able to schedule another interview for them sometime in January, giving them plenty of time to get everything else taken care of, including a Schengen visa (theirs expired last year). We're planning on doing Estonian visas.
I'm a bit worried about COVID vaccines but so far I'm asking them to get Sputnik V since it should be approved by WHO very soon (hopefully). If not - they'll need to get J&J while they're in Europe. Anyone else has any ideas on what to do with the vaccine?
