In the post-World War II period, a more diverse Arab immigrant population came to the US. This new wave included both Christians and Muslims from all over the Arab World; many were urban middle class and enjoyed a high level of education.

Many of the students who came to study in American universities with the intention of returning to their home countries remained here because of employment opportunities. Although Arab students and professionals helped to build a strong post-war America, their immigration resulted in a "brain drain" from the Arab World – a loss of the most skilled and educated.
