For the past several years, the NSC has been the primary office within USCIS for processing Form I-90, Application for Permanent Residence Card. However, effective August 15, 2012, the Lockbox began sending all I-90s to the National Benefits Center (NBC) for processing. Any I- 90 filed prior to August 15th will continue processing at the Nebraska Service Center. NBC will receive all I-90s filed on or after August 15. The transfer of this form to the NBC will free up resources for NSC to review requests for Deferred Action.
