A federal judge in Texas has ruled that the Obama-era DACA program for undocumented immigrants who came to the U.S. as children is illegal. This is the latest ruling in a long-running legal battle over the Deferred Action for Childhood Arrivals program. It blocks the Biden administration from approving new DACA applications or extensions, though permits will remain valid for current recipients. U.S. District Judge Andrew Hanen declared that creating the DACA program was unlawful. He said the Obama administration did not have the authority to create a program through executive action that allows undocumented immigrants who meet certain conditions to remain in the U.S. Advocates say this ruling will affect hundreds of thousands of DACA recipients whose permits are set to expire over the next year and who were hoping to renew them.
