Assembly Bill 308 aims to prohibit the use of state and local funds, as well as federal funds passing through the state treasury, for health care services provided to individuals who are unlawfully present in the United States. Specifically, the bill creates a new statute, 20.926, which states that no funds from the state, counties, towns, or any subdivisions or agencies can be authorized for subsidizing, reimbursing, or compensating health care services for these individuals.

However, the bill includes exceptions to this prohibition. It specifies that the restrictions do not apply if federal law requires such payments or if enforcing the prohibition would lead to the loss of federal funds. This means that while the bill seeks to limit funding for health services to unlawfully present individuals, it acknowledges the necessity of compliance with federal mandates and the importance of maintaining federal funding.
