USCIS — U.S. Citizenship and Immigration Services
USCIS is the DHS agency that adjudicates almost every immigration benefit inside the United States — including H-1B, O-1, L-1, and EB-series petitions; adjustment of status to permanent residence; naturalisation; and humanitarian applications. It was created on 1 March 2003 when the former INS was split between USCIS (benefits) and ICE/CBP (enforcement).

Scope
- Receives and decides Form I-129 (nonimmigrant worker), I-140 (immigrant worker), I-485 (adjustment of status), I-539 (extend/change status), and the naturalisation Form N-400.
- Runs the H-1B lottery each March and manages the annual cap of 85,000 new H-1B visas (65,000 general + 20,000 US-master's).
- Operates the eCIS electronic processing system, five Service Centers, and a network of Field Offices that conduct in-person interviews and ceremonies.
- Funds itself almost entirely from applicant filing fees — so fee schedules (last updated 1 April 2024) drive the agency's operational budget and processing-time performance.
Procedural quirks
- Processing times are published per-form, per-service-center and vary wildly — from 15 business days under Premium Processing for I-129 to several years for family-based I-130s at some service centers.
- Consular visa issuance (at US embassies) is separately handled by the State Department; USCIS adjudicates the petition and the consulate then issues the visa. Both steps can fail independently.
- Policy memoranda from USCIS leadership can change adjudication standards overnight; watch the "Policy Alerts" page and AFM/USCIS Policy Manual updates for live changes.
