Which query would you use to investigate stolen documents?

The appropriate choice for investigating stolen documents is known as SQSD, which stands for "Stolen Document Query." This query specifically allows officers to search databases for information related to documents that have been reported as stolen.

Understanding the importance of this query is critical in the context of asylum and immigration cases, as verifying the authenticity and provenance of documents is essential to ensure the integrity of the application process. Using the SQSD query helps officials identify if the documents in question have a history of theft, which can affect their credibility and the outcome of the case.

The other options, while they may pertain to different types of queries within the framework of information gathering, do not specifically relate to the investigation of stolen documents. Therefore, only SQSD is designed for that specific purpose, making it the correct choice in this scenario.
