A coalition of unions, employers and religious groups filed a lawsuit on Friday seeking to block US President Donald Trump’s bid to impose, open new tab a $100,000 fee on new H-1B visas for highly-skilled foreign workers.

The lawsuit filed in federal court in San Francisco is the first to challenge a proclamation Trump issued two weeks ago announcing the fee as the Republican president moves to further restrict immigration to the United States.

Plaintiffs include the United Auto Workers union, the American Association of University Professors, a nurse recruitment agency and several religious organisations.

They argued that Trump’s power to restrict the entry of certain foreign nationals does not allow him to override the law that created the H-1B visa programme.
