Innovator Visa, UK
The Innovator visa allows residence in the UK for up to three years, and is targeted at experienced business owners looking to start a novel business in the UK. The primary requirements of the Innovator Visa are that you are approved by an official approving body, which are mostly incubators and research organizations. You must also be able to prove your ability to sustain yourself during your stay (an oddly low minimum of £945 maintained for three months prior to your arrival). For new businesses, you must also have access to $£50,000+ in investement funding. This visa type may be extended perpetually in three-year increments.
