IAQ
Immigration Alien Queries are an unacceptable invasion of migrant privacy. These can return information on migrants without legal status including civil deportation letters or even warrants for their arrest. This is profoundly unjust and potentially harmful to their future applications for permanent residency status. It is inconceivable that fingerprints and other biometric information could be used to reveal their identity and status to immigrant enforcers, who might then hunt them down and deport them.
