H-1B Nebraska Service Center (NSC / LIN) Guide (2026)
The Nebraska Service Center processes a subset of H-1B petitions, historically including cap-exempt cases and certain premium processing filings. LIN receipt numbers identify NSC cases.
Nebraska Service Center Jurisdiction
The Nebraska Service Center (NSC) has been assigned different H-1B caseloads at different times. NSC has historically adjudicated cap-exempt H-1B petitions, O-1 petitions, and certain other employment-based visa categories. USCIS regularly publishes current jurisdiction assignments at uscis.gov — always verify before filing to ensure you are sending to the correct lockbox address.
NSC Receipt Numbers
Nebraska Service Center receipt numbers begin with LIN (Lincoln, Nebraska): LIN25-xxx-xxxxx. If your I-797 receipt notice has a LIN prefix, your case is being adjudicated at NSC. This is relevant for tracking processing times — check uscis.gov for current NSC H-1B processing times separately from CSC/VSC/TSC.
Cap-Exempt H-1B at NSC
Historically, the Nebraska Service Center has processed a significant share of cap-exempt H-1B petitions filed by universities, nonprofit research institutions, and government research agencies. Cap-exempt petitions generally follow the same adjudication standards as cap-subject petitions but can be filed year-round with no lottery registration requirement.
NSC Processing and Premium Processing
Premium processing is available at NSC on the same terms as other service centers: I-907 upgrades standard processing to 15 business days from receipt. NSC standard processing times are posted at uscis.gov/working-in-the-united-states/temporary-workers/h-1b-specialty-occupations and updated monthly.
