Where did immigrants to the US come from in 1965?

In 1965, the Immigration and Nationality Act significantly changed U.S. immigration policy, leading to an increase in immigrants from Asia, Latin America, and Africa. Prior to this, the majority of immigrants had come from Europe. The new law eliminated quotas based on national origin, resulting in a more diverse influx of immigrants from countries such as Mexico, the Philippines, India, and Vietnam. This marked the beginning of a shift in the demographic makeup of the U.S. immigrant population.
