What are the conditions for applying for a marriage visa with Ukrainian women to immigrate abroad?

There is no such thing as a wedding visa immigrant in Ukraine, and the civil war in Ukraine has never stopped. The country is in chaos and the economy is very poor. Now many Ukrainian women want to apply for a marriage visa and immigrate to China. I hope you can also help Ukrainian women escape from Ukraine and get green cards in China. By the way, working in Ukraine, the income is lower than that in China, and the local unemployment rate is too high. Unless you are a veteran and want to be a mercenary in Ukraine.
