Ten-Print Scanning. U.S. Embassy Seoul began collecting ten fingerprints from all immigrant and non-immigrant visa applicants on October 22, 2007. This transition to ten-print collection is a worldwide initiative and a crucial step toward maintaining the State Department’s policy of “secure borders and open doors.”.he U.S. Embassy will continue to process visa applicants courteously and efficiently while updating our security procedures. The Embassy encourages people who plan to travel in 2008 to apply for visas early, well before the summer rush which usually occurs between May and August.
