immigration control

Immigration control refers to the policies and practices governments use to regulate the entry of individuals into their country. Historically, immigration has brought significant social, economic, and cultural benefits, contributing to the development of multicultural societies. However, concerns about national identity, economic competition, and the strain on public services have led to restrictive policies, a stance often termed nativism.12

In the United States, the Supreme Court ruled in 1849 that Congress, not individual states, holds the sole authority to regulate immigration, classifying it as "foreign commerce". Throughout the 21st century, attempts at comprehensive immigration reform have stalled, with policy changes often enacted through presidential executive orders. These have included programs like DACA (Deferred Action for Childhood Arrivals) and stricter measures such as border wall construction and increased deportations. Immigration remains a contentious issue, influencing political discourse and elections.3456
