Bio

Sandra leads Snap2Pass's editorial on document photo compliance. She has reviewed thousands of accepted and rejected applications across the US State Department, UK HM Passport Office, Passport Seva, COVA, ImmiAccount, and Schengen consulates. Her work focuses on the small specification details — file size bands, head-to-frame ratios, and country-specific rejection patterns — that most generic photo guides miss.
