Two layers of coverage #
Coverage has a broad layer and a deep layer, and it is worth knowing which one you are looking at:
- The registry is broad: nearly every country carries a baseline set of general visa classes, so any corridor has a starting point.
- The verified document library is deep but narrower: actual human-approved links to official documents exist where curators have done the work, and that set grows corridor by corridor.
A corridor appearing in the registry does not mean every document for it is verified yet. The coverage and transparency page shows live, computed counts of what is actually verified today; the docs deliberately do not duplicate numbers that go stale.
The general class taxonomy #
Where a country does not yet have detailed, country-specific visa classes, it carries eight general purpose-of-travel classes:
| Class | Covers |
|---|---|
| Tourist / Visitor | Tourism and short visits |
| Student | Study at any level |
| Work / Employment | Employment-based travel |
| Business | Business trips, conferences, trade |
| Family reunification | Joining family members |
| Transit | Passing through en route elsewhere |
| Medical treatment | Travel for medical care |
| Other | Anything not covered above |
Countries with detailed curation carry their own official class names on top of this baseline.
Reading a corridor page #
Each corridor page under Visa corridors lists the registered visa classes for that country and, for each, the document links that have been verified. An empty or short document list means curation has not reached that corridor yet, not that no documents are required.
