The Department of Homeland Security says more than 200,000 Salvadorans who have lived more than two decades in the United States can remain in the country another 18 months, marking one of the Biden administration’s final acts on immigration policy.

The extension helps safeguard one of the nation’s largest immigrant groups from the incoming Trump administration, which has made mass deportations a top priority.

President Joe Biden’s administration extended temporary protected status for 600,000 Venezuelans and more than 200,000 Salvadorans in the US just 10 days before Donald Trump takes office vowing mass deportation of immigrants.
