Visa requirements change without warning. A wrong answer from us could mean a rejected application, a missed flight, or a wasted embassy fee. This page explains exactly how we source, verify, and update the data behind every check on VISA CHECKER.
We cross-reference every visa requirement against a minimum of two primary government sources before showing it to users. If our data conflicts with what you find on an official embassy website, please email [email protected] and we will review and correct it within 24 hours.
Our AI system continuously monitors official government immigration portals, embassy websites, and industry databases including IATA Timatic. When a source page changes, the system flags the affected routes for human review.
A large language model reads the raw policy text and extracts structured data: visa type, maximum stay, processing time, fee, required documents, and any conditional rules (e.g. dual nationality, prior refusals). The model is instructed to flag ambiguity rather than guess.
Each extracted data point is checked against at least two independent sources. Where sources conflict, we show the more conservative requirement and note the discrepancy. We never show a 'visa-free' result unless at least two primary sources confirm it.
High-traffic routes (e.g. Nigerian passport to UK, Indian passport to Canada) are reviewed monthly. Lower-traffic routes are reviewed quarterly. Emergency updates are triggered within 48 hours when a government announces a policy change.
Visa policy can change without notice. Processing times and fees are estimates based on recent reports and may vary. We always recommend verifying requirements directly with the relevant embassy or consulate before submitting your application.
