The government has launched the HQ-UK programme with the aim of encouraging US companies to set up international headquarters in the UK.
HQ-UK is a joint initiative between UK Trade and Investment (UKTI), the Department for Business, Innovation and Skills, the Department for Culture, Media and Sport, and Tech City.
The initiative will help US companies expand into the UK by offering concierge services, faster visa applications, and priority border control at UK airports, among other services.
HQ-UK was launched by Baroness Joanna Shields (pictured), former Tech City chief executive and the prime minister's digital advisor, who described the UK as a place for technology companies to scale up.
"Nowhere beats the UK as an international hub for tech companies looking to thrive, innovate and grow," she said.
"As someone who has spent 25 years operating on both sides of the Atlantic, I have no hesitation in saying that the UK is now the best place to build a global business."
The government claims that more companies choose the UK as a base than anywhere else in Europe, and that the country is second only to the US in receiving the most inward foreign direct investment.
Access to talent from four of the world's top six universities, low corporation tax, and a series of technology clusters across the nation, were highlighted as attractive for US companies looking to build headquarters in the UK.
Nick Bray, chief financial officer at security firm Sophos, supported the government's claims that the UK has world-leading technology skills.
"It's a very flexible labour market with great talent to hire, with an equal skillset to what some people would arguably think is some of the best talent in the world," he said.
The government also noted that the UK has specialist visas for companies wanting to bring in skilled workers from beyond Europe. These include the Exceptional Talent Visa, and entrepreneur and investor visas.
David Quantrell, EMEA general manager at US company Box, which has its international headquarters in London, encouraged US companies to follow its example. "I would urge you to look at the UK as a serious proposition," he said.

Driving the growth of Britain's technology industry is also high on the agendas of the Conservatives, Labour and the Liberal Democrats. MPs clashed recently over different approaches to UK start-ups ahead of the General Election.
