A federal judge has ruled that a controversial work-permit program for foreign students will survive a challenge from a union representing U.S. technology workers that wanted it killed.

A who’s who of Bay Area tech giants including Google, Apple, Facebook, Uber, Tesla, HP, Oracle and Salesforce had joined the fight, seeking to protect the Optional Practical Training program — which is often used as a path to an H-1B visa. In a court filing last year, they argued that the program, which gives foreign students and graduates up to three years to live and work in the U.S., expands job opportunities for American workers by spurring economic activity.
