There is a new scheme for Tier 1 Exceptional Talent which will be introduced in April 2011.
This route is designed for internationally regarded migrants in Arts, Science and Humanities to work and eventually settle in the UK. There will be a limit of 1,000 visas available per year.
This category does not require an offer of employment from a UK sponsor. However, the person will need to provide official approval of an accredited body. The list of approved organisations will be released by the UK Border Agency in the near future.
Applicants granted Tier 1 (Exceptional talent) will be granted a period of 3 years 4 months. Extensions will be granted for a further 2 years. Settlement can be applied for after 5 years.
