Some of America’s biggest tech firms on Monday backed a challenge to President Donald Trump’s restrictions on foreign workers.

Amazon, Apple and Facebook are among the companies arguing that the temporary visa bans will damage US firms.

Trump imposed restrictions on some foreign workers to safeguard jobs for Americans during the virus pandemic.

Many of those affected by the measures are technology workers from India.

Microsoft, Netflix, Twitter and other big technology companies also backed the lawsuit, which was filed last month by major US business associations.

Those industry groups included the National Association of Manufacturers, which represents 14,000 firms, and America’s biggest business association, the US Chamber of Commerce.
