If you don't want to read the pre-amble, you can skip straight to the second "Accordingly" to see the details.
"Whenever the President finds that the entry of any aliens or of any class of aliens into the United States would be detrimental to the interests of the United States, he may by proclamation, and for such period as he shall deem necessary, suspend the entry of all aliens or any class of aliens as immigrants or nonimmigrants, or impose on the entry of aliens any restrictions he may deem to be appropriate."
Also interestingly, it seems to only explicitly impose restrictions on entry into the US. But most visa holders are already in the country, and atleast according to this proclamation, they'd be unaffected.
