What steps should I take if the State Department has denied my passport because of past-due support?
You must contact your child support agency to make satisfactory arrangements to pay your past-due support. If more than one state reported your name to the Passport Denial Program, you must reach an agreement with all states involved before your passport hold is released.
Once you have paid your past-due support in full or reached a satisfactory payment agreement, the state(s) will request that OCSE remove your name from the Passport Denial Program. After the State Department has processed the withdrawal request from OCSE and cleared its system, you may contact the National Passport Information Center at 1-877-487-2778 or make an appointment at a regional passport agency to complete the process.
Check with your child support agency for more information.
