USCIS

U.S. Citizenship and Immigration Services provides official information about the immigration benefits and services it administers. Its website includes forms, filing instructions, case tools, application guidance, and access to supported online accounts.

Users should identify the exact form or case type before beginning a process. Eligibility, fees, evidence, and filing methods depend on current official instructions. USCIS is distinct from the Department of State's visa and passport functions and from other agencies involved in immigration enforcement or border operations.
