President Donald Trump will soon sign an executive order temporarily barring foreigners seeking green cards from coming to the U.S., in an effort to support Americans who lost their jobs as a result of the coronavirus pandemic.

At a Tuesday press conference, Trump said that the upcoming order, which could be signed as soon as tomorrow, will affect those seeking green cards but will not block those entering as tourists, students or foreigners on temporary work visas. The ban could bar both spouses and immediate relatives of U.S. citizens as well as foreign workers coming to the U.S. on employment-based green cards.

Trump said that the order would "help put unemployed Americans first in line for jobs as America reopens."

"It would be wrong and unjust for Americans laid off by the virus to be released with new immigrant labor flown in from abroad," he said. "We must first take care of the American worker."

The pause will remain in effect for 60 days, at which point officials will reexamine economic conditions. Trump also said that the administration will consider potential additional immigration measures moving forward to protect U.S. workers.
