Startup businesses are the lifeblood of the U.S. economy, introducing new ideas and innovations, and bringing competition that can improve productivity, aid consumers and provide new opportunities for both investors and workers. However, U.S. immigration policy does not look kindly on foreign nationals who seek to create businesses in America. In fact, in a practical sense, it may be easier to stay in the United States illegally and start a business than to start a business and gain legal temporary status and permanent residence (green card) as the owner of that business."
