Which agency is abbreviated as CUSA?

The abbreviation CUSA stands for Citizenship USA. This agency is involved in issues related to citizenship and immigration processes within the United States. Its focus aligns with the functions of various agencies that manage the citizenship application process, promote civic engagement, and ensure that individuals understand their rights and responsibilities as citizens.

The other choices, while they may sound plausible, do not accurately represent any known agency or common abbreviation used in the context of immigration or citizenship in the U.S. For instance, Counter Unlawful Surveillance Agency and Crisis Unit Support Agency do not exist as recognized entities within federal government operations regarding citizenship or asylum, and Central Unified Security Agency is not a known agency. Hence, Citizenship USA is indeed the correct identification for the acronym CUSA.
