Which of the following is an acceptable source for documented data used in detainee classification?

The final order of removal is a formal document issued by an immigration court. It confirms the legal standing of an individual’s immigration status and provides concrete information about their history, including any legal proceedings that have taken place. As an official record, it holds significant legal weight and reliability, making it an essential source for documented data in detainee classification.

In contrast, unconfirmed information from a detainee lacks verification and may not be trustworthy, thereby being less suitable for classification purposes. Personal opinions of officers, while they may provide insight, are subjective and not based on documented evidence. Witness testimony, although potentially valuable, can be inconsistent and difficult to corroborate, making it less reliable than an official court order. Thus, the final order of removal stands out as a credible and authoritative source for detainee classification.
