DOS announced in a December 30, 2004 Federal Register notice that the Biometric Visa Program became permanent on October 24, 2004. See 69 FR 78515 (December 30, 2004). The program had begun as a pilot on September 22, 2003. DOS now only issues visas that are machine-readable, tamper-resistant, and use biometric identifiers. The biometric identifiers include digital fingerprints of the left and right index finger and a digital photograph of the visa holder. Biometrics in visas were required by the Enhanced Border Security and Visa Entry Reform Act of 2002.
