The measure, known as parole in place, is part of a broader executive power dating from the early nineteen-fifties, which every President since then has exercised to grant special protection to particular categories of people. Biden has made liberal use of his parole authority, allowing more than a million people to enter the country in the past three years, about a quarter of whom have been displaced Ukrainians and Afghans. Republicans have attacked Biden for using this power too broadly, and there’s no question that the Administration has been creative. Last year, to reduce unauthorized crossings at the southern border, the Department of Homeland Security developed a parole program that has admitted more than four hundred thousand Venezuelans, Haitians, Nicaraguans, and Cubans who had financial sponsors in the United States. Conservative state attorneys general filed a lawsuit to block the program, but in March it was dismissed in a federal district court. There will almost certainly be legal challenges to Biden’s latest policy, too.
