Which law provided the framework for modern immigration policy after 1965?

The Immigration and Nationality Act of 1965 played a pivotal role in reshaping American immigration policy by abolishing an earlier quota system that heavily favored European immigrants. Instead of using national origin as a basis for immigration quotas, this act prioritized family reunification and skills. It aimed to create a more equitable immigration framework, allowing for a greater influx of immigrants from Asia, Africa, and Latin America, reflecting the United States' growing diversity.

By emphasizing the importance of family ties and professional qualifications, the 1965 act laid the groundwork for the contemporary immigration system, which has continued to evolve around these principles. The changes initiated by this legislation are still evident today, influencing not only who can enter the country but also how immigration contributes to the socioeconomic fabric of American society.

The other laws mentioned did play significant roles in immigration policy but were either responses to specific issues, such as the legal status of refugees and those in the workforce, or focused on enforcement measures without fundamentally altering the broader framework established in 1965.
