What is a key responsibility of ICE concerning customs?

The key responsibility of ICE concerning customs is enforcing laws related to trade and immigration. This encompasses a variety of tasks, including investigating and enforcing laws related to the import and export of goods, as well as ensuring compliance with immigration regulations. ICE's role plays a significant part in maintaining the integrity of U.S. borders and its trade system.

In the context of customs, ICE works to prevent illegal imports and to prosecute individuals or organizations that violate trade laws, which is essential for protecting national security and economic interests. This responsibility also extends to aspects of immigration enforcement, as the crossing of borders often intertwines trade and the movement of people.

The other options do not align with ICE's primary functions. Regulating state tax policies is under the jurisdiction of state agencies and has no direct connection to ICE. Monitoring local school attendance is typically the responsibility of educational institutions and local authorities. Providing social services to immigrants is not a primary function of ICE, which focuses more on enforcement and regulation than on social services.
