Important: Physical Size ≠ Universal Document Requirement
A physical dimension template (such as 50.8 × 50.8 mm) determines the outer crop boundary. However, exact facial composition (chin-to-crown height), background shade rules (white vs light grey), eyeglass policies, and upload file size ceilings belong strictly to the issuing government authority. Always check the authoritative document specification below for your specific application.
