Vintage Watch Close-up 148227778, National Benefits Center NBC Processing Times: USCISUSCIS National Benefits Center serves a unique role within USCIS as part of the Field Operations Directorate. NBC opened in 2001 in Lee’s Summit, Missouri; its original name was the Missouri Service Center. This is why NBC receipt notices begin with the letters “MSC.” Below are updated NBC processing times as of November 30, 2017, posted February 01, 2018.

NBC’s primary mission is to prepare immigration applications for adjudications that require an interview at a USCIS Field Office. Preparing such an application requires considerable time and effort, including background and security checks and reviewing evidence to support eligibility.

NBC Workload and Processing

Note that missing evidence will not delay the processing of an N-400 application at NBC. But if the missing evidence is not provided at the time of interview in the applicable USCIS Field Office, USCIS may delay adjudication or even deny the application.

Each USCIS Field Office, not NBC, determines Form I-485 and Form N-400 processing times since NBC does not conduct final adjudication. Please check our website at for processing times of such applications at your local USCIS Field Office.

If you need to contact the NBC regarding your case, please call our National Customer Service Center (NCSC) at 1-800-375-5283. The representative taking your call will send an electronic message to NBC that they will  answer within 15 days. NBC answers expedite requests for certain applications within 5 days.

Contacting NBC

You can submit an inquiry about your Form I-765 if your case has been pending more than 75 days.
