Sunday marks the centennial of one of the darkest, most discriminatory immigration turns in American history: the passage of the Immigration Act of 1917. The law banned immigrants from the Asiatic Barred Zone, a region that included Saudi Arabia, most of China, Afghanistan, Pakistan, India, Malaysia, Thailand and Indonesia. Now, 100 years and 16 presidents later, some see that history repeating itself.
