MIAMI — About 600,000 Venezuelans and more than 230,000 Salvadorans already living in the United States can legally remain another 18 months, the Department of Homeland Security said Friday, barely a week before President-elect Donald Trump takes office with promises of hard-line immigration policies.

Biden’s administration has strongly supported Temporary Protected Status, which he has broadly expanded to cover about 1 million people. TPS faces an uncertain future under Trump, who tried to sharply curtail its use during his first term as president. Federal regulations would allow the extensions to be terminated early, although that’s never been done before.

Homeland Security also extended TPS for more than 103,000 Ukrainians and 1,900 Sudanese that are already living in the U.S.

The TPS designation gives people legal authority to be in the country but it doesn’t provide them a long-term path to citizenship. They are reliant on the government renewing their status when it expires.
