This bill mandates the Congressional Budget Office (CBO), in collaboration with the Council of Economic Advisers, to conduct and publicly release a study on the long-term economic impact of immigration policies implemented from January 20, 2025. The study, to be completed within 180 days of enactment or by the end of the 119th Congress, will specifically assess the 20 to 40-year economic effects across various sectors. It will examine impacts on industries like public sector, service, farm, and healthcare workers, as well as innovation and retention in STEM fields. The analysis will also cover effects on public safety due to pervasive fear, immigration flows, and overall demographic changes. Furthermore, the CBO study is directed to evaluate the policies' effects on productivity, technological innovation, remittances, consumer spending, investment, and overall GDP contribution. A critical component is assessing the impact on small businesses and the net fiscal impact of mass deportation on Federal, State, and local tax revenues. To ensure comprehensive data collection, the Department of Homeland Security, Bureau of Labor Statistics, and Internal Revenue Service are required to share necessary data with the CBO Director upon request.
