The best UK business visa for entrepreneurs is the Innovator Founder Visa. This visa is specifically designed for individuals who want to establish an innovative and scalable business in the UK. To qualify for this visa, you must secure an endorsement from an approved UK endorsing body that assesses the business idea. The visa is granted for three years, with the option to extend, and it also provides a direct pathway to permanent residency in the UK. Unlike the previous Innovator Visa, the Innovator Founder Visa does not require a minimum investment fund, making it more accessible for entrepreneurs with strong business ideas but limited starting capital.
