What governmental body typically oversees immigration policies?

The Department of Homeland Security (DHS) typically oversees immigration policies in the United States, which aligns with the option selected. The DHS was established in response to the events of September 11, 2001, and its responsibilities include securing the country's borders, refocusing immigration policies, and managing immigration enforcement. This governmental body encompasses agencies such as U.S. Citizenship and Immigration Services (USCIS) and Immigration and Customs Enforcement (ICE), which are directly involved in overseeing immigration matters, proposing immigration reforms, and enforcing immigration laws.

Understanding the role of DHS is essential, as it reflects the comprehensive approach the U.S. government takes towards managing immigration and ensuring national security. While other options may deal with matters related to foreign relations or immigration in other contexts or countries, they do not encapsulate the specific oversight tasked to DHS regarding immigration policy in the United States.
