The purpose of this legislation, known as the "Ensuring Children Receive Support Act," is to ensure that parents who owe significant child support payments are held accountable by revoking their U.S. passports. This aims to encourage compliance with child support obligations, thereby supporting the financial well-being of children. The key provision of this law states that the Secretary of State must revoke the U.S. passport of any individual who has a child support arrearage exceeding $2,500, based on a certification from the Secretary of Health and Human Services.
