The Biden administration is withdrawing the US from agreements with three Central American countries that restrict the ability of people to seek asylum at its southwest border.
The move is part of a broad effort to undo the the immigration policies of former president Donald Trump.
Secretary of State Antony Blinken said on Saturday he had notified El Salvador, Guatemala and Honduras the US had started a formal process of terminating agreements that were part of Trump's effort to restrict asylum.
The agreements, which had been on hold since early in the COVID-19 pandemic, required many seeking asylum at the US-Mexico border to go instead to one of the three Central American countries to pursue claims.
"The Biden administration believes there are more suitable ways to work with our partner governments to manage migration across the region," Blinken said in a statement announcing the immediate suspension of the agreements and their eventual termination.
The secretary of state said the administration intends to work with the Central American nations to reduce some of the insecurity and poverty that cause people to flee in the first place while maintaining the security of the US border.
"To be clear, these actions do not mean the US border is open," he said.
"While we are committed to expanding legal pathways for protection and opportunity here and in the region, the United States is a country with borders and laws that must be enforced."
The Trump administration pushed the Central American nations to accept the agreements as a way to reduce the number of people seeking asylum in the United States.
Critics said it amounted to a US retreat from its obligations under international law to help people fleeing persecution since neither of the three countries could credibly provide refuge.
Since the start of the pandemic, the US has been quickly expelling nearly everyone apprehended at the border or seeking asylum under a public health law to prevent the spread of COVID-19.
President Joe Biden signed a series of executive orders Tuesday that ended Trump immigration policies or put them under review.
He also created a task force to reunite Central American families forcibly separated at the border under a zero-tolerance program in 2018.
