Routine service for DS-5504 applications means that your application will be processed in the order it is received, and you can expect to receive your corrected passport within 4-6 weeks. Expedited service means that your application will be processed in 24 hours if you appear in person at a regional passport agency or within 2-3 weeks if you submit your application and supporting documents to a passport center. Expedited service requires an additional fee and proof of travel within 72 hours or a life-or-death emergency.
