An unlimited fast-track visa scheme to attract the world's top scientists and researchers will open in the UK next month.
Johnson paired the announcement of the Global Talent route program with a pledge of £300m for research into advanced mathematics. The money will help fund researchers and doctoral students whose work in math underpins myriad developments such as safer air travel, smart phone technology and artificial intelligence.
In his announcement, Johnson said he wanted to send a message that Britain was open to the "most talented minds in the world" as the country left the EU.
As we leave the EU I want to send a message that the UK is open to the most talented minds in the world"
"The UK has a proud history of scientific discovery but to lead the field and face the challenges of the future we need to continue to invest in talent and cutting-edge research.
With Brexit day approaching on 31 January, the prime minister added: "As we leave the EU I want to send a message that the UK is open to the most talented minds in the world, and stand ready to support them to turn their ideas into reality."
The Global Talent visa route - to be opened on February 20 - will not be capped and is set to replace the current Tier 1 exceptional talent route.
Applications were previously capped at 2,000 per year but the limit was never reached. For instance, it was used successfully by 550 people in 2018/19.
Philip Barth, head of immigration at Irwin Mitchell said: "The introduction of the global talent visa is a welcome one, though it could be on the face of it little more than a rebranding and slight expansion of the current exceptional talent visa.
"For instance the government has decided to lift the cap on the amount of applicants to the global talent visa; however, this was a limit that was never actually reached under the exceptional talent visa scheme. It's likely the exceptional talent and global talent visas are very similar in nature.
"It is vital that the eligibility criteria for the visa are not too onerous for individuals applying to come to the UK, otherwise the scheme will never get off the ground. If handled correctly, the global talent visa has a great chance of attracting the best candidates from around the world at a time where our economy will need it most."
Applicants will not need a job offer before arriving in the UK under the visa and it will provide an accelerated path to settlement for all scientists and researchers who are endorsed.
