Alphabet, Apple, Facebook, Uber and Stripe, along with a consumer packaged goods company and others, are working together on a letter opposing U.S. President Trump’s travel ban, according to sources.

Tech companies are leading the effort but are working to involve other industries, the sources say. The letter will be the first major push from big U.S. businesses to try to support immigration in the wake of a recent travel restriction order by Trump.

The restrictions affect the tech sector in a huge way. If it continues, Apple will have issues with WWDC in a few months.
