A UK Business Visa, typically issued under the Standard Visitor Visa category, allows individuals to visit the UK for short-term business activities. These activities can include attending meetings, conferences, training sessions, or negotiating contracts. The visa permits stays of up to 6 months and does not allow for paid work or long-term employment. For those intending to establish or run a business in the UK, other visa types like the Innovator Founder Visa may be more appropriate.
