What we measured, and what we could not.

Methodology and findings from our own corpus of visitor-stay rules — coverage, counting models, evidence quality and the limitations we would rather state than hide.

• Visitor-stay rules for high-mobility passports: coverage, counting models and rolling windows [2026]A methodology and findings report on how long visitors may stay, built only from the routes in our own rulebook that carry a government source for the claim being made. Of the 1,555 passport-to-destination routes we generate a page for, 228 carry no length of stay at all and 35 carry no official government source. This report says what those gaps are, where the counting models actually differ, and how to re-derive every figure in it.
