I have so many ladies asking me for information about how to come to the USA I decided to write my first Blog.
The first thing I can say is contact the US Embassy, either in Ukraine or any other country you are in if you left Ukraine.
Second the people here in the USA are very sympathetic to anyone from Ukraine and will treat you well.
Now I will list some places where you can look up information about getting assistance here.
Go to Benefits.gov
Refugee and Entrant Assistance
next try,
Office of Refugee Resettlement
then try,
U.S. Department of Health and Human Services

I hope that this will help you with your questions about coming to the USA.
