With the debate over immigration to the US as fiery as ever, a new analysis suggests that Silicon Valley would be lost without foreign-born technology workers. 

About 71% of tech employees in the Valley are foreign born, compared to around 50% in the San Francisco-Oakland-Hayward region, according to a new report based on 2016 census data.
