Biometrics appointment is a process in which fingerprint and a photograph of a person is used during the interview with USCIS. When the interview with United States Citizenship and Immigration Services (USCIS) is scheduled, to complete the biometrics appointment process, the applicant is required to provide biometric information, typically fingerprint impression, photograph, and any other information if required.
After the biometrics appointment process is complete, the collected biometric information of the applicant is sent to FBI and other legal departments. The information is then stored in the national database for tracking purposes. Mostly, biometrics appointment is scheduled and held for the processing of the Green Card for United States.
