Methodology & data

How the information is built.

Every pathway is structured from official sources, dated, and explicit about what is unknown.

Coverage

World Immigrant maps immigration pathways by country and category. Coverage reflects published records, not every route available worldwide.

Official sources first

Material requirements link to government or official program sources. Citations identify the source section used for each field.

Freshness and snapshots

Last checked shows when a source was reviewed. Retained snapshots make cited evidence traceable when official pages change.

Uncertainty stays visible

Unknown means the available evidence does not support a reliable value. Not applicable is kept separate from missing information.

Human-reviewed updates

Automated scans detect source changes, but canonical immigration records change only after human review.

Informational boundary

This database is informational and does not determine eligibility or replace advice from an authorized professional.
