visa?destination=JPN&passport=USA

Look up the visa requirement for a traveler with a given passport visiting a destination country.

Look up the visa requirement for a traveler with a given passport visiting a destination country. Pass passport and destination as ISO-3166 alpha-3, alpha-2, or country name (e.g. passport=USA destination=Japan). Returns the requirement category — 'visa free' (with visaFreeDays, the allowed days), 'visa on arrival', 'e-visa', 'eta' (electronic travel authorization), 'visa required' (must arrange in advance), or 'no admission' — plus a plain-language description and the resolved passport/destination names. Data from the community-maintained Passport Index dataset (MIT). Informational only — not official immigration advice; verify with the destination's embassy before travel.
