One significant effect of the Immigration and Nationality Act was an increase in Hispanic and Asian immigrants.

To arrive at this answer, you can research the Immigration and Nationality Act of 1965, also known as the Hart-Celler Act. This act abolished the national origins quota system that heavily favored immigrants from Northern European countries. It introduced a new system that prioritized family reunification and skills-based immigration. As a result, restrictions on immigration from Asian and Hispanic countries were lifted, leading to an increase in immigrants from these regions.
