Which of the following is NOT a type of fraudulent document in COSS?

The correct answer highlights that a modified genuine document does not fit the definition of a fraudulent document as understood in the context of COSS (Customs and Border Protection's Office of Standards and Support).

A genuine document refers to an original, valid document that has not been illegitimately altered or forged. In contrast, fraudulently obtained genuine documents involve items that were originally real but acquired through deceitful means, such as using someone else's identity or lies to gain access to the document. Completely counterfeit documents are entirely forged versions of legitimate documents designed to deceive authority figures.

While the other categories represent various forms of fraudulent activity, a modified genuine document, while potentially altered, still retains its original validity, meaning it does not embody the characteristics typically associated with fraudulent documents. This distinction is what makes the choice of a modified genuine document stand out as not fitting the definition of a fraudulent document type according to COSS standards.
