The United States was founded by immigrants, but new data suggests that immigrants are still fueling America's start-ups.
The United States, a country of immigrants, has an economy that has long been fueled by an influx of talent from abroad. Increasingly, immigrants are driving innovation research and starting their own companies. But current immigration policies make it tough for them to stay. The annual demand for visas greatly outweighs the supply, sending would-be entrepreneurs--and their big ideas--back to their home countries.
