President Joe Biden's administration has extended by 18 months the temporary protected status for migrants from El Salvador, Sudan, Ukraine and Venezuela due to "extraordinary and temporary conditions" in those nations.

Homeland Security says about 600,000 Venezuelans and more than 200,000 El Salvadorans living in the U.S. can legally remain another 18 months.

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.
