Venture into the underground cave that is the US Citizenship and Immigration Service’s National Records Center.  Millions of paper records have been centralized into a single, state-of-the-art facility, dramatically improving the integrity of USCIS’ recordkeeping and cutting the time spent on file retrieval—a vital component of application processing—from weeks and even months to only a few days.  Also learn about the USCIS – National Benefits Center (NBC). The NBC’s primary mission is to prepare applications for adjudication that require an interview at a USCIS Field Office including conducting background and security checks and reviewing the evidence an applicant submits to support their eligibility for the benefit.
