Joe Biden is on his heels amid a migrant surge at Mexico border

Within weeks of Inauguration Day on Jan. 20, the Biden administration had reversed many of the most maligned Trump-era immigration policies, including deporting children seeking asylum who arrived alone at the U.S.-Mexico border and forcing migrants to wait in Mexico as they made their case to stay in the United States.

Somehow, they didn’t see it coming. Within weeks of Inauguration Day on Jan. 20, the Biden administration had reversed many of the most maligned Trump-era immigration policies, including deporting children seeking asylum who arrived alone at the U.S.-Mexico border and forcing migrants to wait in Mexico as they made their case to stay in the United States.While the administration was working on immigration legislation to address long-term problems, it didn’t have an on-the-ground plan to manage a surge of migrants. Career immigration officials had warned there could be a surge after the presidential election and the news that the Trump policies, widely viewed as cruel, were being reversed. Now officials are scrambling to build up capacity to care for some 14,000 migrants now in federal custody — and more likely on the way — and the administration finds itself on its heels in the face of criticism that it should have been better prepared to deal with a predictable predicament.
