USCIS has updated its Policy Manual to enhance vetting for family-based immigrant visa petitions, effective August 1, 2025. This guidance clarifies eligibility, filing, interviews, and decisions. The goal is to ensure genuine family relationships and combat fraud, which undermines lawful immigration pathways. USCIS prioritizes robust screening to protect national security by identifying and processing individuals with harmful intent for removal. This strengthens confidence in the family-based immigration system.
