The Trump administration is using an existing federal enforcement tool to revoke or deny passports for parents who owe significant unpaid child support, aiming to pressure noncustodial parents into settling overdue payments. Officials say the approach has already prompted some parents to make immediate lump-sum payments, including sums exceeding £80,000 (around $100,000), reinforcing the policy's stated goal of prioritising children's welfare.

The mechanism itself is not new: since 1996, the State Department has worked with the Department of Health and Human Services' Office of Child Support Enforcement to run the Passport Denial Program, which blocks new passport applications and renewals for people with substantial child support arrears. The current administration has stepped up enforcement under this programme, framing it as a practical way to compel compliance, though the article does not specify the exact debt threshold or the precise number of parents affected under the renewed push.
