The U. S. Citizenship and Immigration Services (USCIS) has issued instructions on making inquiries on pending cases with the USCIS' four Service Centers. The step-by-step instructions are as follows:
Step 1: Contact the National Customer Service Center (NCSC) at 1-800-375-5283. The NCSC can assist customers, community-based organizations and liaison groups with case related inquiries. Before calling the NCSC please have available your receipt number, alien registration number, type of application filed and date filed. During your call we recommend that you take note of the following information:
-The name and/or id number of the NCSC representative
-The date and time of the call
-Any service request referral number, if a service referral on a pending case is taken
Step 2: If more than 30 days have passed since contacting the NCSC and the issue has not been resolved or explained, the petitioner or applicant can email the proper USCIS Service Center to check the status of the case.
- California Service Center: csc-ncsc-followup@dhs.gov
- Vermont Service Center: vsc.ncscfollowup@dhs.gov
- Nebraska Service Center: ncscfollowup.nsc@dhs.gov
- Texas Service Center: tsc.ncscfollowup@dhs.gov
Emails should be sent to the Service Center where the case is pending. The receipt notice will indicate EAC for the Vermont Service Center, SRC for the Texas Service Center, LIN for the Nebraska Service Center, and WAC for the California Service Center.
When contacting the Service Centers by email, it is required to provide the information outlined in Step 1. If the NCSC did not issue a service request after the phone call, indicate the reason the NCSC representative did not issue the request.
Step 3: In the event there is no response within 21 days of contacting the appropriate Service Center, the petitionerr or applicant may email the USCIS Headquarters Office of Service Center Operations by email at: SCOPSSCATA@dhs.gov. According the USCIS' information, a response should be received from this email address in ten days.
