Foreigners trying to move to the United States can seek to become “lawful permanent residents” — otherwise known as receiving a green card — which allows them to live in the country and eventually seek citizenship.
Mr. Trump’s proclamation did not block American citizens from trying to bring their spouses or children to the United States. But it did bar other foreigners, including the relatives of green card holders and those seeking green cards based on a job offer.
An analysis by the Migration Policy Institute at the time estimated that the policy could affect as many as 660,000 people.
Mr. Biden has vowed to return the United States’ immigration policies to what they were before Mr. Trump became president. He has increased the number of refugees that can be resettled in the country, and he has taken steps to process claims of asylum seekers waiting in squalid camps at the Mexico border.
But Mr. Biden has also proposed a more far-reaching overhaul of the nation’s immigration laws, fulfilling a campaign promise he made to send legislation to Congress on the first day of his presidency.
In his legislation, the president would provide an eight-year path to citizenship for most of the 11 million undocumented immigrants living in the United States. The legislation has been proposed in the House and Senate by Mr. Biden’s Democratic allies, but it is unclear whether it can earn enough Republican support to pass the Senate.
