A federal judge has denied President Donald Trump’s effort to impose a $100,000 fee on new H-1B visa applicants seeking high-skilled jobs in the United States, which would have imposed the massive fee on tens of thousands of foreign workers.

U.S. District Judge Leo Sorokin of Boston, who was appointed by former President Barack Obama, on Monday ruled against Trump’s six-figure fee on the basis that it was an illegal tax Congress had never approved.
