Which type of biometric information is specifically required on the FD-936 form?

The FD-936 form is specifically designed for the collection of biometric data in relation to immigration enforcement processes. Among the types of biometric information that can be gathered, fingerprinting is a vital component due to its uniqueness and reliability in identifying individuals. Fingerprints are collected to ensure accurate identification of individuals involved in immigration cases, which is crucial for maintaining security and integrity in immigration enforcement.

While facial recognition data, signature verification, and voice recordings can also serve as forms of biometric identifiers, the FD-936 form explicitly requires fingerprints to be submitted. This requirement is rooted in established practices and standards for biometric data collection in law enforcement and immigration contexts. The use of fingerprints allows for effective background checks and identification searches, which are essential for processing applications or cases related to immigration enforcement.
