B‑1 Business Visitor
The B‑1 visa is intended for business trips to the U.S. to conduct business on behalf of a foreign employer. The B‑1 visitor may not be employed to work for a U.S. employer. Permitted B‑1 activities include business meetings, conferences or seminars, contract negotiations, consultations, litigation, sales calls, plant tours, market research, contract or warranty follow‑up, and formal classroom training (but not on‑the‑job training). Tourists are eligible to seek B-2 visitor visas.
