WASHINGTON — The Biden administration warned on Tuesday that the United States expected to make more apprehensions along the southwestern border this year than at any time in the past two decades, underscoring the urgency for the White House to develop solutions for the chronic problems with immigration from Central America.
The grim prediction by Alejandro N. Mayorkas, the secretary of homeland security, came as President Biden was being assailed for his handling of a surge at the border involving thousands of unaccompanied children and teenagers from the region — with attacks coming from the right for not being tough enough and from the left for not being humane enough.
The president has pleaded for time and patience, blaming his predecessor for dismantling the immigration system in his zeal to keep foreigners out. But even Mr. Biden’s top advisers acknowledge that after unwinding the harsh policies of President Donald J. Trump’s, there is no easy or quick fix for a problem that has been a recurring crisis.
“We have no illusions about how hard it is, and we know it will take time,” Mr. Mayorkas said in a statement on Tuesday as the House prepared to vote this week on several immigration measures and the administration rushed to provide more housing for the young migrants arriving at the border. But, he added, “We will get it done.”
restart the Obama-era Central American Minors program, which was intended to allow some children to apply in their home region for permission to live in the United States with a parent or other relative. When Mr. Trump ended the program, about 3,000 Central American children had been approved for travel to the United States.
It will take time to ramp up the program, which has strict vetting requirements, in order to verify the relationships of the children and their relatives.
Now, the administration is eager to examine even broader efforts to consider asylum applications remotely.
The administration is already testing a system where migrants, who were told by the Trump administration to wait along the border in squalid camps in Mexico, can use an app on their cellphones to apply for asylum and track their cases. That kind of system might be expanded more broadly, officials said.
“This is the road map going forward for a system that is safe, orderly and fair,” Mr. Mayorkas said.
Many of the changes Mr. Biden wants are included in comprehensive immigration legislation he sent to Congress on his first day in office. But that bill is a long way from becoming law, especially with Mr. Trump and other Republicans again using immigration to stoke their partisan base.
