Review Questions

• How has the concept of national security influenced U.S. immigration policies throughout history?
  • The concept of national security has significantly influenced U.S. immigration policies by prioritizing the need to protect citizens from external threats. Throughout history, periods of conflict or perceived danger have led to stricter immigration controls and policies aimed at vetting newcomers. For example, during World War II, Japanese internment camps were established due to fears about espionage, while post-9/11 reforms resulted in heightened scrutiny of visa applicants from certain countries viewed as high-risk.
• Evaluate the impact of national security considerations on border security measures in the United States.
  • National security considerations have led to increased investments in border security measures in the United States. This includes enhancements in physical barriers, surveillance technologies, and law enforcement resources aimed at deterring illegal immigration and trafficking. The emphasis on border security reflects a broader strategy to safeguard the nation from potential threats and unauthorized entry, which can complicate relations with neighboring countries and affect migrant rights.
• Assess how changes in national security policy can affect civil liberties and public perception of immigration.
  • Changes in national security policy often lead to tensions between enhancing security measures and protecting civil liberties. For instance, after events like 9/11, policies such as increased surveillance and stricter immigration controls were implemented under the premise of protecting national security. This raised concerns about racial profiling and discrimination against certain groups, which can shift public perception toward viewing immigrants with suspicion rather than as contributors to society. The challenge lies in finding a balance that ensures both safety and respect for individual rights.
