Writing in response to a request for comment from the Department of Homeland Security on the issue of “Public Charge Ground of Inadmissibility,” Urban Institute experts raise concerns based on prior research that the proposed rule would reduce participation in essential health, nutrition, and other programs among low-income families with children, including many US citizen children. As a result, fewer people would have their critical needs met, causing harm to family and child well-being in both the short and long terms. Further, they suggest that the proposed rule understates its impact on the receipt of benefits in immigrant families with children and on government costs because of the greater uncompensated care burdens, adverse health impacts, and decreased economic potential that would result for US citizen children from their reduced receipt of public benefits.
