The document is a complaint filed in United States District Court by 20 U.S. states against the Department of Homeland Security and other federal agencies and officials. The complaint challenges DHS's new parole program that allows up to 360,000 aliens annually from Cuba, Haiti, Nicaragua, and Venezuela to enter the US and receive work authorization for up to two years. The plaintiff states argue the program exceeds DHS's limited parole authority and was established without proper rulemaking procedures. They claim the program will cause them irreparable harm by allowing large numbers of additional aliens to enter their states. The complaint asks the court to declare the program unlawful and enjoin its implementation.
