The Wall Street Journal reports that:

A new non-partisan study on entrepreneurship gives some credence to the tech industry’s stance that American innovation benefits from robust immigration.

The study from the National Foundation for American Policy, a non-partisan think tank based in Arlington, Va., shows that immigrants started more than half of the current crop of U.S.-based startups valued at $1 billion or more.

These 44 companies, the study says, are collectively valued at $168 billion and create an average of roughly 760 jobs per company in the U.S. The study also estimates that immigrants make up over 70% of key management or product development positions at these companies.
