Thousands of immigrant children in the United States could soon be left to face immigration court alone as Washington prepares to let a key federal legal aid contract expire on Friday. If no extension is approved, tens of thousands of undocumented and unaccompanied minors risk losing access to lawyers, forcing many to navigate complex court proceedings without legal representation. Advocacy groups warn the decision could dramatically reshape how vulnerable children experience the U.S. immigration system. In Washington, even a single contract can change thousands of young lives.
