Which of the following is NOT a function of USCIS in relation to immigration?

The correct answer is based on the specific functions of the United States Citizenship and Immigration Services (USCIS). USCIS primarily focuses on administering immigration and naturalization processes, which includes functions such as providing assistance for naturalization, offering educational resources regarding citizenship (which falls under providing citizenship education), and overseeing immigration benefits, such as work permits and visas.

USCIS is not primarily engaged in immigration enforcement; that role falls to other government entities such as the Department of Homeland Security (DHS) and Immigration and Customs Enforcement (ICE). Thus, while USCIS plays a vital role in helping individuals navigate the immigration system and ensuring proper processing of applications and petitions, it does not actively enforce immigration laws or conduct raids and detentions, which are associated with immigration enforcement activities. This distinction clarifies why the option related to immigration enforcement is not a function of USCIS.
