U.S. District Judge J. Campbell Barker declared the Biden administration's 'Keeping Families Together' immigration policy illegal, blocking pathways to citizenship for undocumented spouses of Americans. This ruling arose from a lawsuit by Texas and 15 other states alleging executive overreach. The program aimed to let approximately 500,000 undocumented immigrants apply for green cards without leaving the U.S. The Biden administration disagrees with the ruling and is evaluating an appeal as Donald Trump prepares to assume office with stricter immigration policies, heightening uncertainty for affected families.
