Donald Trump has signed an executive order temporarily suspending immigration into the US during the coronavirus pandemic.
The US President said the policy was designed to protect the jobs of American workers as the economy is impacted by the Covid-19 outbreak.
He said he signed off on the order, which will last for 60 days but could be extended, just before his daily coronavirus briefing at the White House on Wednesday night.
"This would ensure that unemployed Americans of all backgrounds will be first in line for jobs as our economy opens," Mr Trump told reporters.
Critics have accused the US leader of using Covid-19 to ram through hardline immigration policies ahead of the country’s election in November.
The hundreds of thousands of temporary work visas issued by the US each year will not be affected by the 60-day pause.
Also exempt are the spouses and young children of American citizens, green card applicants currently already in the US, and those seeking entry to work as doctors.
Nurses and other healthcare professionals are also exempt from the order.
The policy is expected to face legal challenges.
