Yes, the U.S. Department of State will generally deny a passport if you owe 2,500 dollars or more in child support. To clear it you must pay down arrears through your state’s child support agency so they can report you compliant. After the agency certifies you, the State Department can resume processing your passport application. This federal consequence applies regardless of where the child support order was issued. It is separate from court based enforcement like contempt. Contact your local child support office for payoff details and certification steps.
