This is stated in the widespread statement by the US Secretary of State Anthony Blinken.

“Today, the United States took action in accordance with Presidential Proclamation 8015, imposing visa restrictions on 43 persons in Belarus responsible for undermining Belarusian democracy,” Blinken said in a written statement.

As emphasized, these individuals are "generally prohibited from entering the United States."

Earlier, the spokesman for the US State Department Ned Price said that Washington supports a peaceful political dialogue in Belarus.
