Which of the following expands the acronym COA?

The acronym COA stands for "Class of Admission." This term is commonly used in immigration contexts, particularly when referring to the specific category under which an individual is admitted to the United States. It plays a crucial role in understanding an individual’s immigration status and eligibility for various benefits, such as asylum. Each class of admission has specific criteria and entitlements associated with it.

In the context of immigration, particularly asylum processing, understanding the class of admission helps officers assess the specifics of an applicant's situation, including their rights and responsibilities while in the United States. This knowledge is fundamental to making informed decisions in asylum cases. Other options, while they contain valid terms, do not relate to the context of immigration or asylum processing as directly as "Class of Admission."
