unhindered immigration and effects on US per capita GDP

Peterson has just graduated from college and is now a junior member of the staff of a U.S. senator. He has been asked to draft a statement detailing the senator's position on the economic growth implications of immigration. His research on the topic has uncovered the following facts. First, more than a fifth of scientists actively involved in research at the US universities are immigrants.
