There are two pressing issues in today’s debate about immigration in the United States: the sheer number of legal immigrants who are entering the country, and the impact of illegal immigration from countries such as Mexico. The goal of legal immigration has always been to continue with the American tradition of welcoming those who are oppressed and otherwise marginalized in their societies. In the recent century, a second goal was added which was to attract skilled and educated immigrants to come to the United States and to contribute to its efforts to become a world leader in industry, research, and the arts. This goal was realized as the United States has indeed become a world leader in the 20th century, with world class institutions of higher learning that attract researchers and educators from all over the world. In fact, the second world war is known to have resulted in major movements of educators who were fleeing the devastation of the war from European institutions to American universities.
