WASHINGTON — Thousands of migrant children are backed up in United States detention facilities along the border with Mexico, part of a surge of immigration from Central Americans fleeing poverty and violence that could overwhelm President Biden’s attempt to create a more humane approach to those seeking entry into the country.
The number of migrant children in custody along the border has tripled in the past two weeks to more than 3,250, according to federal immigration agency documents obtained by The New York Times, and many of them are being held in jail-like facilities for longer than the three days allowed by law.
The problem for the administration is both the number of children crossing the border and what to do with them once they are in custody. Under the law, the children are supposed to be moved to shelters run by the Health and Human Services Department, but because of the pandemic the shelters until last week were limiting how many children they could accommodate.
The growing number of unaccompanied children is just one element of an escalating problem at the border. Border agents encountered a migrant at the border about 78,000 times in January — more than double the rate at the same time a year ago and higher than in any January in a decade.
refused to call a “crisis” but could nevertheless become a potent political weapon for his Republican adversaries and upend his efforts to legalize millions of undocumented immigrants.
The president has proposed overhauling the nation’s decades-old immigration system by making it easier for asylum seekers and refugees, expanding legal pathways for foreign workers, increasing opportunities for family-based immigration and vastly reducing threats of mass deportations. His State Department announced on Monday that foreigners rejected after Jan. 20, 2020, under Mr. Trump’s travel ban could try to obtain visas without paying additional fees.
Hundreds of migrant families are also being released into the United States after being apprehended at the border, prompting predictable attacks by conservatives.
Liberal politicians are denouncing the expansion of detention facilities and railing against the continued imposition of Trump-era rules intended to prevent the spread of the coronavirus from immigrants. And advocates for families separated at the border during Mr. Trump’s administration are pressuring the president to move faster to reunite them.
Together, it has put Mr. Biden on the defensive in the early days of his presidency as he attempts to demonstrate a tone very different from his predecessor’s.
The immigration system Mr. Biden envisions will take months, if not years, to be fully implemented, forcing the administration to scramble to find space for children and rely, for now, on a rule that swiftly returns adults and most families to their home countries.
For now, Mr. Biden has broken from his predecessor in not applying the pandemic emergency rule to children, meaning the United States is still responsible for caring for them until they are placed with a sponsor.
