The HEART Act of 2026 directs the Department of Health and Human Services to establish an Office of Immigrant Community Mental Health and Resilience to help communities provide mental health services to people experiencing trauma from immigration law enforcement actions. The office will fund mobile mental health response teams, emergency counseling vouchers, and grants to eligible organizations such as health centers, schools, and community groups serving affected communities. The legislation also requires the office to support workforce development for culturally competent mental health providers, conduct public awareness campaigns about health care rights, and submit annual reports to Congress on the public health impacts of immigration enforcement. Critically, the bill includes strict privacy protections prohibiting the office from sharing any collected data or information with the Department of Homeland Security or other immigration enforcement agencies. The bill authorizes funding by redirecting unspecified sums from existing appropriations in prior legislation.
