What is the difference between an Applicant Service Center (ASC) and a call center?
An ASC is a facility contracted by the U.S. government to collect biometric data from visa applicants prior to submission to the consular section. The call centers provide other visa-related services, including making visa appointments, answering visa-related questions, collecting other applicant information, and assisting applicants in choosing a DHL location where the passport and visa can be picked up.
