Charta Visa Travel Authorization Data

Open data on travel authorizations (ESTA, UK ETA, ETIAS, Canada eTA, US B1/B2 visa): which nationality needs which product, the government fee in its own currency, validity, processing, the official government source for every row, the 2026 'Cost of Crossing Borders' report tables, and a monthly time series of U.S. visitor-visa interview wait times as published by the U.S. Department of State.

Charta Visa is an independent private service, not a government website. Government fees are stated separately and paid to the authorities in full.

Published by Charta Visa — see the research hub for the reports built on this data and the developer docs for the live API and MCP server. Licensed CC BY 4.0 (see LICENSE). Machine-readable metadata: croissant.json (Croissant 1.0 / schema.org Dataset), CITATION.cff.

Files

File	Vintage	What it is
`visa-requirements.csv` / `.json`	2026-06-01	386 rows — 195 nationalities × the destinations Charta Visa serves (US, UK, Canada, Schengen/ETIAS). Product, government fee + currency, service availability, processing, validity, and the official government source URL for every row.
`entry-cost-2026.csv`	2026-06-01	The tables behind The Cost of Crossing Borders — 2026: fee history per authorization and the per-nationality authorization burden in USD. Two sections, each with its own header row; `#` lines are comments.
`us-visa-wait-times/<asOf>.json`	monthly	One snapshot per U.S. Department of State vintage of the Global Visa Wait Times table (B1/B2 next-available appointment and average wait, per consular post). Files are never rewritten, so the folder is a time series. Latest: `2026-07-28.json` (241 posts, source last updated 2026-06-18).
`us-visa-wait-times/index.json`	—	Manifest of the snapshots above (asOf, source vintage, post count).

Live copies of the current files are also served from the site: visa-requirements.csv, visa-requirements.json, entry-cost-2026.csv, latest wait times.

Method and honesty notes

Derived, not hand-typed. Every row is generated from the same registry Charta Visa's website renders from (VISA_REGISTRY, the eligibility engine, and the per-product official-source map), by scripts/export-datasets.mjs in the app repository. If the site changes, the data changes with it.
Government fees are the authority's published fee, in the authority's currency. Charta Visa's own service fee is never included in any file.
Wait times are transcribed, never estimated. Non-numeric published values (NA, < 0.5 Month) keep their raw string and get null for the day count. Months are the Department's 30-day increments.
ETIAS is pre-launch (service_available = false): the EU has not opened the portal; rows carry the announced fee and validity for reference.
Files are deterministic (sorted rows, no generation timestamps), so a diff between two releases is a real data change.
