US Immigration from Ukraine

I (US citizen) and my husband (Ukrainian citizen, US resident) were married in the states but now live in Ukraine. I'm being asked to provide proof of name change since I took his last name when we married.

The only documents I have are our marriage certificate, old and new passports, IDs, and SSNs. Ive spoken to the county clerk and the social security office in the US but everyone agrees that a "proof of name change" document does not exist in my country. I've explained this to the immigration offices but they insist it must be out there.

I know this question is more related to outgoing immigration but maybe someone had to do something similar? My embassy offered to notarize an affidavit but that was deemed irrelevant as well. Super frustrated, any points in the right direction are appreciated!

Case status !

Interview canceled ! Notice Ordered .

what does this mean ?

My wife has been document-ally qualified since April 29th. The NVC hasn t scheduled an interview at the Embassy yet. How long are people waiting for Kiev? Also I keep reading about other people scheduling their own interview? How is this? I called the NVC and they said that is impossible.

My Fiancee swears she can't even change planes in Europe to come to the U.S. due to Covid restrictions. How is this possible when all flights from Ukraine fly through Amsterdam or Germany, etc.?

My fiancee and her son will be here in 2-3 weeks and I need some decent healthcare until we're married and she goes on mine. I've been unable to find any good affordable options. Anyone know of any?
