On May 14, 2026, the U.S. Attorney’s Office for the Northern District of Illinois (NDIL) announced a new Individual Self-Disclosure Program offering qualifying individuals three potential forms of relief in exchange for voluntary self-disclosure and cooperation: letter immunity, a deferred or non-prosecution agreement, or criminal prosecution with substantial sentencing relief. The Program’s express three-tier structure distinguishes it from many other federal self-disclosure programs, which generally focus on the possibility of a non-prosecution or deferred prosecution agreement. To qualify, individuals must provide a complete and truthful proffer, cooperate fully with law enforcement, testify if required, and disgorge any criminal proceeds, among other requirements. This post summarizes the Program’s key features and highlights how it compares to similar self-disclosure initiatives adopted in other jurisdictions.
