How did U.S. immigration policy change from the 1950s to the present?

U.S. immigration policy from the 1950s to the present reflects significant shifts in approach, particularly with a focus on regulating the flow of immigrants from various regions. The statement that immigration policy has restricted the number of immigrants from different areas recognizes the historical context of laws and quotas established over the years.

For instance, the Immigration and Nationality Act of 1965 replaced earlier quota systems that favored European immigrants with policies aimed at uniting immigrant families and attracting skilled laborers. However, over subsequent decades, various policies, such as the establishment of numerical caps on visas and specific restrictions based on security concerns or regional stability, have led to limits on immigration from certain countries or regions.

This change indicates a more selective immigration system, which reflects the current political and social considerations surrounding immigration. Such a policy approach acknowledges the balance between welcoming new residents and addressing national security, economic stability, and social integration challenges, resulting in a more restrictive nature regarding immigration flows from various parts of the world.
