US Immigration from Tajikistan

I got this Email today

We previously notified you of the date and time of your immigrant visa interview at the U.S.Embassy/Consulate General in MOSCOW, RUS.

Due to unforeseen circumstances, we have to cancel this interview. We will schedule a new interview appointment as soon as possible and notify you of the date and time. There is no need for you to take action at this time.

If you have any questions, please contact us by following the instructions at https://nvc.state.gov/inquiry.

However They NEVER NOTIFIED US of an Interview!

June 1st Our Lawyer sent emails to expedite our cases. No response. July 1st Due to the situation in Moscow, (as of Aug 1st 2021, NO VISA SERVICES,) our lawyer asked to transfer to Almaty, Kazakhstan. because Almaty is supposed to handle Immigration visas for citizens of Tajikistan. How long dose one wait until calling NVC and asking about the statuses of out cases? or will they move us to the bottom of the stack? We all are frustrated with all the waiting! we just want to be together!

Okay dated May 14th This was on the Embassy's web site.

Event: Temporary Resumption of Consular Services The Russian government has informed U.S. Embassy Moscow of its intent to postpone the prohibition of U.S. Mission Russia s employment of foreign nationals. Consequently, through July 16, U.S. Embassy Moscow will temporarily resume routine U.S. citizen services, including passport services, Consular Reports of Birth Abroad, and limited notarial services. Please visit our website for instructions on scheduling an appointment. We will also provide immigrant visa processing for priority and urgent cases.

has anyone heard or seen anyone getting interviews/Visas since this was posted?

With the recent roller coaster due to the political strife between Russia and the US. there is this

https://ru.usembassy.gov/message-to-u-s-citizens-u-s-mission-russia-2/

it states they will provide Immigrant visas for Priority and urgent cases. What would take to qualify as Priority or Urgent?
