Visa rules change unpredictably. Most consumer-facing planners parrot a single source, when it's wrong, every traveller it touches gets wrong information. JetlyGo cross-checks every rule against multiple independent public datasets, surfaces the confidence level on every answer, and re-verifies weekly. Here's exactly how.
Every rule in our database cites a source URL. We currently combine four independent inputs and use a cross-source agreement signal to decide what to show end users.
Community-maintained dataset of every passport × every destination pair, updated quarterly. Provides our base coverage of 199 passports across 199 destinations (~39,000 rules). Used to initially seed every rule at low confidence, only promoted to visible when a second source agrees.
“Visa requirements for [nationality] citizens” pages are continuously maintained by volunteer editors and cite primary government sources (Timatic, embassy publications, IATA). We parse the structured tables and use them to confirm or contest our other sources. When Wikipedia and the Passport Index agree, the rule becomes visible. When they disagree, we mark it disputed.

UK gov.uk publishes travel advice for 226 destinations with a machine-readable last-updated timestamp. We use these timestamps as a freshness signal: when their advice for a country updates, our corresponding rules get flagged for re-verification, even if our other sources haven't noticed yet.

For the most frequently-checked nationalities (initially Indian passport holders, expanding over time), we manually review each rule against the destination's official immigration website or embassy publication. Curated rules sit at medium confidence by default; the owner promotes individual rules to high confidence via the internal review tool after personally verifying.

Every rule carries a confidence tag. Only rules at high, medium, or disputed confidence are shown to end users, or low rules where two independent sources agree. Anything weaker stays hidden until a human reviews it.
A Cloudflare cron job runs every Monday at 03:00 UTC. It refetches the official source URL for a rotating slice of rules, hashes the visible content, and compares to the snapshot from last week. Any page that changed flags its rule for human re-verification within 24 hours. UK gov.uk travel-advice update timestamps are checked the same way.
We never silently pick a winner. If our Passport Index dataset says a destination is visa-free for an Indian passport but the Wikipedia article says embassy-visa-required, the rule is marked disputed, both versions are surfaced, and the user sees a “sources disagree, verify with the embassy” warning.
Always verify with the destination's embassy or official immigration website before booking travel. Visa policies can change overnight, even our weekly re-check can miss same-day announcements. JetlyGo's visa data is provided for planning convenience, not legal advice. We are not an immigration adviser, embassy, or government agency.
If you spot a rule you believe is incorrect, please email hello@jetlygo.com with the source URL, we typically update within 24 hours.
