Help evacuating my parents from Ukraine

Hello, my name is Khrystyna Simonson. I have been in the US since 2012 and became a US citizen in 2019. Since I came to the US, I have been missing my parents (Yourii Arkhipov and Alla Arkhipova) immensely. After getting my citizenship, I thought it wouldn't take long to bring them here, but the war changed everything.

My parents are in Kryvyi Rih, Ukraine, not far from the war zone. I have been trying to get a visa for my parents for the past two years, and the last step left is for them to have the interview in Frankfurt, Germany. I would like some help with getting them to the Polish border and either plane or train tickets to Frankfurt, as well as hotel accommodations while they get their medical examinations and interview process. I would like to get them a flight to the US as well, if possible. Because of the sudden war, I haven't been able to save enough money to get them out of Ukraine safely. I really appreciate any help you can provide.
