The U.S. government is set to start revoking the passports of parents who owe substantial amounts in child support, targeting those with arrears exceeding $2,500. This initiative is part of a new policy aimed at enforcing child support payments more effectively. Reports indicate that the plan will initially affect thousands of parents who have failed to meet their financial obligations, potentially expanding further in the future. This action has drawn attention amidst discussions on voter ID requirements and other immigration-related policies.
