b. Timeliness of Interview: The interview with you is the most significant part of the visa issuing process to ensure the full and correct application of the law. Section 237 of Public Law 106-113 and subsequent legislation require that the Department establish a policy under which immediate relative (and fianc (e)) visas be processed within 30 days of receipt of the necessary information from the applicant and the Department of Homeland Security (DHS); all other family-based IVs must be processed within 60 days.
