US Immigration from Belarus

Does anybody have any idea how much time does it take to receive an IR-1 interview letter from the embassy in Tbilisi, Georgia? Can't find any information anywhere. It's been a little more than 8 months since we got the approval letter from NVC (July 12, 2023).

I am submitting the AOS packet soon, and I am curious if I need two or three G-1450 and where to put them in the packet.

I-130 -> G-1450

I-485 -> G-1450

But what about the biometrics fee? Can it be combined with I-485 G-1450? Or should I submit a third G-1450 specifically for Biometrics?

Also, where do I include the G-1450? On top of everything? Or before each form (G-1450 and then I-130, etc...)

If I do it before each form, should I put it before or after the G-1145?

Background: My naturalized us citizen wife is sponsoring her mother to become a permanent resident. Belarussian Passports have two ID pages, one that is in Russian and Belarussian, and the other which is in English. The English page does not list the middle name. The Russian and Belarussian page lists the patronymic which may or may not be considered a middle name .

For form I-693, we left my wife s mother's middle name blank because it is not on the English page of her Belarussian passport and this was the first document we completed.

It is completed and sealed by the Civil Surgeon so we cannot make changes to it.

Will it cause any issues if we list my wife s mother s middle name on other documents (I-130, I-485, etc), but not the I-693?

Hi we are filing the i-751 in a few weeks and just found out that we should have let USCIS know about our new address within 10 days which we didn't do. I submitted the change of address online just now but what are the potential issues here? How would they know what date we moved anyway?

In the last six months, anyone from Belarus managed to obtain a Schengen visa at the Polish visa center for the purpose of visiting the US consulate?
