President Donald Trump will sign an executive order extending foreign-worker restrictions through the end of the year, the White House announced.

The new order extends restrictions originally enacted in April due to the coronavirus pandemic and expands on the previous directive, which blocked most people from receiving a permanent residency visa — or green card. The new order also prohibits visas for most guest workers who come to the U.S. for temporary or seasonal work, but exempts farm workers, among others.
