Latitude

Sojourn tallies where you've been. Latitude looks the other way - what a longer stay would trigger, and what you'd need to check before you rely on it.

Latitude is a flag engine, not a permission engine. It never tells you you're cleared to stay. It shows what crossing a line would trigger - and what you'd need to verify yourself before relying on it.

New to how these rules work? The plain-language guides explain them, no tool required: how the Schengen 90/180 rule works, US state residency when you don't have a home, and what actually triggers California residency.

A flag isn't a decision

Latitude can tell you what a longer stay would trigger. Whether it's worth triggering is the part I write about - every week or so.

Not legal, immigration, or tax advice. Latitude is a personal planning aid that flags thresholds and points you at official sources - it is not authorization to stay and not a substitute for a professional. Residency and entry rules depend on far more than day counts (domicile, ties, the number actually written on your permit), assume a US passport, and change by government announcement. Every flag shows when its rule was last checked; confirm anything that matters with the official source linked on it before you rely on it. Your stays stay in this browser - nothing is sent anywhere.
