States must act swiftly to pass their own state ICWA laws to strengthen the implementation of the federal law. ICWA creates a floor of strong protections, but states are free to build on this foundation and further support tribal child welfare systems. And where the Supreme Court has identified limitations on what federal ICWA requires — for example, in the context of searching for placements that satisfy ICWA’s preferences — states can and should require more. States are also well poised to work with tribal nations to craft their own ICWA laws that cater to specific issues that might arise in their jurisdiction.
