H4 Travel to US - Corona travel ban from Europe

Hello, My wife is in Europe, has h4 stamped, can she travel to US now. US has issued travel ban from Europe. Any idea?

Unfortunately, I do not think she can come in now from Europe, even if she has visa. This is due to the travel ban for Europe area. Double check with US embassy in that country, before you plan anyhting.
