Last summer we sent my wife’s parents to Budapest to interview for their B2 visas. It wasn’t fun. They got Covid there, and were
very sick. Anyways, they were approved in Budapest, even though the translator said most of her Russian clients are denied. But Budapest might be an option if they’re still allowing non-residents for interviews. Of course a valid Schengen visa is required, and they did have that prior. They own a house in Greece we visit, so they keep their visa current. Greece loves Russians.
also, Azerbaijan or Armenia can get you to Istanbul. From there, you have direct flights to the USA. My biggest question for you, is…where was your child born? I’m assuming Russia. So you will have a lot of work to get her US citizenship. My wife and I are currently doing the opposite, and getting our daughter her Russian citizenship, so she can receive her benefits in Russia, since they’ll provide you with free food and money and doctors etc. way better than the USA in my opinion!
forget the Poland embassy as they are handling everything now and are notoriously anti Russian, and denying most people there. I would suggest even looking for US embassies that process non residents like Israel was doing, or Thailand. I’d go to Asia before Poland. But that’s just me. Like others have suggested, you need to email many embassies to determine if they’ll accept you.
don’t lose faith and don’t feel trapped in Russia. I hope you figured it out already.
