In 1960, Pew notes, 84 percent of U.S. immigrants were born in Europe or Canada; 6 percent were from Mexico, 3.8 percent were from South and East Asia, 3.5 percent were from Latin America and 2.7 percent were from other parts of the world. In 2017, European and Canadian immigrants totaled 13.2 percent, while Mexicans totaled 25.3 percent, other Latin Americans totaled 25.1 percent, Asians totaled 27.4 percent and other populations totaled 9 percent.
The 1965 act has to be understood as a result of the civil rights movement, and the general effort to eliminate race discrimination from U.S. law, says Gabriel “Jack” Chin, immigration law professor at University of California, Davis and co-editor of The 1965 Immigration and Nationality Act: Legislating a New America.

That kind of argument was novel, but consistent with the anti-racism of the Voting Rights Act of 1965 and the Civil Rights Act of 1964.”
The act, Edward Kennedy argued during the Senate floor debate, went to the “very central ideals of our country.”
“Our streets may not be paved with gold, but they are paved with the promise that men and women who live here—even strangers and new newcomers—can rise as fast, as far as their skills will allow, no matter what their color is, no matter what the place of their birth,” he said.
