Trump did not hint at making any drastic immigration moves during his lengthy daily coronavirus news briefing earlier Monday evening. Immigration has largely taken a back seat during the pandemic as the president hopes to salvage a strong economy that had become one of his major campaign points in the lead-up to the November election.

Trump has previously boasted that closing the borders to foreigners traveling from China demonstrated his administration‘s serious and early response to the threat from the coronavirus. International travel has come to a virtual standstill as countries across the globe have imposed travel restrictions to prevent the spread of the disease.

Trump’s tweet did not make clear what specific action he would take: He could simply suspend entries for a period of time, or cancel a specific program altogether for the year.

The Department of Homeland Security is still drafting the executive order, according to three people familiar with the situation. One possibility that has been discussed is an exemption for temporary guest workers, including those who work on farms.

When asked what promoted the decision, a top DHS official responded: “22 million unemployed Americans and counting due to Covid-19.”

Since the pandemic began, the administration had already restricted foreign visitors from China, Europe, Canada and Mexico, and had paused processing for immigrants trying to come into the U.S. on non-worker visas because of office closures. That means the impact would probably address only immigrants coming here to work.
