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.
