Live Assistance

Those who need more help than automated service can provide, can be transferred to a customer service representative.

Other tasks that can be accomplished are:

  • A change of address for pending applications

  • Request for Emergency Rescheduling of an Appointment
    Please make every effort to appear for your scheduled appointment for fingerprinting, interview, or other processing. Failure to appear can delay the processing of your case and can result in you not receiving the benefit for which you applied. However, if an emergency arises and you absolutely cannot make your appointment, call the NCSC to request for rescheduling. The NCSC will record the information and pass it on to the local office, which will make the final decision whether or not to reschedule your appointment.

  • General Case Status Checks
    At this time the NCSC provides specific information about the status of an individual application by phone IF you electronically filed OR filed at a Service Center AND have a receipt/tracking number. The NCSC can answer many questions about case status for customers who:
    • have a pending application or petition at service center for naturalization, or

    • filed another kind of application at a local USCIS office.
