The DS-160 is the Online Nonimmigrant Visa Application form used by the U.S. Department of State for individuals applying for a temporary visa to the United States. This includes tourist visas (B-1/B-2), student visas (F/M), exchange visitor visas (J), petition-based work visas (H, L, O, P, etc.), and K fiancé visas. Each applicant, including children, must complete a separate DS-160 form. The form collects biographical, travel, and security information, which is reviewed by consular officers during the visa interview. Completing the DS-160 is the first essential step for anyone seeking a U.S. nonimmigrant visa.
