The NBC receives Forms submitted by applicants from the Lockbox. In general, a
lockbox is a post office box used by organizations to accelerate the collection
of receivables. In the case of the NBC, the Lockbox is used to accelerate these
receivables (which are applications and petitions) by electronically capturing
data and images from these Forms and by performing fee receipting and fee
deposit. USCIS employees oversee Lockbox operations and perform case resolution
activities on cases processed at the Lockbox. Cases are reviewed at the Lockbox
for basic information only, including the completion of the following items:

  • Basic biographical information
  • Signature on the Form 
  • Jurisdiction of the submitted Form 
  • Correct fee 
  • Basic Eligibility (including visa availability) of applicant
