Immigrant deep tech founders have significantly contributed to the trillion-dollar U.S. economy. Yet, U.S. immigration policies for foreign-born founders remain challenging to navigate. The U.S. may lose to the global competition for deep tech talent in countries like Australia, Canada, Germany, and U.K. where access to entrepreneurship visas are easier to obtain. If the U.S. wants to continue leading the world in deep tech innovation, it can expand immigration policies for foreign-born entrepreneurs to make building startups here more attractive — not only to promote innovation but to support the U.S. economy.
