LR-121 prohibits providing state services to people who are not U.S. citizens and who have unlawfully entered or unlawfully remained in the United States. Under LR-121, every individual seeking a state service, such as applying for any state licenses, state employment, unemployment or disability benefits, or aid for university students, must provide evidence of U.S. citizenship or lawful alien status, and/or have their status verified through federal databases. State agencies must notify the U.S. Department of Homeland Security of noncitizens who have unlawfully entered or remained in the U.S. and who have applied for state services.
The costs associated with verifying U.S. citizenship or lawful alien status will vary by agency and cannot be precisely determined. However, on-going costs may include: hiring and training state personnel to use various federal databases; software, hardware and search charges; and information assessment and management costs.
