International doctoral students and researchers cannot easily reconcile conflicting enrollment data from different government sources

International doctoral students, university administrators, and immigration researchers struggle to get accurate enrollment numbers because OECD data and SEVIS data (US government tracking system) report conflicting figures with no clear methodology to reconcile them. This creates confusion for visa applications, funding decisions, policy analysis, and institutional planning. Current solutions fail because the data sources use different definitions, collection methods, and reporting timelines without transparent documentation.
