As part of a policy overhaul, Britain has launched a visa scheme for 'exceptionally talented' people, including scientists. UK immigration policies were revised last year to reduce the number of migrant workers allowed in (see Nature 467, 491; 2010); the latest scheme came into effect on 9 August. The science portion will be administered by the Royal Society in London, which can recommend 300 researchers per year whose potential to become leaders in their fields is evidenced by major prizes or fellowships. Applicants need not be sponsored by an employer. Visas are valid for 40 months, after which visiting scientists may apply for a two-year extension, followed by possible settlement.
