Mexico visitor caps your time in Mexico at 180 days per visit. The statute attaches its consequence at 181 days or more, so 180 is the last safe count. Up to 180 days, but the officer writes the number on the form. Thirty days is now common — count what is written, not the maximum.
Who it applies to
This matters most if you are:
- A visitor on a short-stay visa or visa waiver making several trips a year.
- A long-term traveller stitching stays together and losing track of the cumulative count.
- Anyone booking a return trip who needs to know the last day they may legally stay.
The rule — and why it exists
Mexico visit length. At most 180 days in Mexico per visit — written as <=180 / VISIT.
Why it exists: a short-stay allowance is a promise to leave. The cap, and the way it is counted, is what lets a state admit visitors without treating every visit as immigration.
Counting the days
- Count the days of each stay in Mexico on its own, arrival and departure days included.
- No single stay may exceed 180 days.
- Leaving and re-entering starts a new stay — but frequent or back-to-back visits invite refusal as a de facto resident.

Examples
Example 1 — A stay of 170 days
Stays: Mexico 2026-03-01 → 2026-08-17. Checked on 2026-08-17.
Result: Mexico visit length: 10 of 180 days left (170 used in Mexico).
Example 2 — A stay of 185 days
Stays: Mexico 2026-03-01 → 2026-09-01. Checked on 2026-09-01.
Result: Mexico visit length: over the limit — 185 of 180 days, first exceeded 2026-08-28.
Example 3 — Two visits of 125 days each
Stays: Mexico 2026-01-10 → 2026-05-14; Mexico 2026-06-01 → 2026-10-03. Checked on 2026-10-03.
Result: Mexico visit length: 55 of 180 days left (125 used in Mexico).
Exceptions & edge cases
- National visas and residence permits. Days spent under a long-stay visa of that country are usually not short-stay days.
- Transit. Airside transit generally does not count; a day on which you cross the border does.
- Overstays. Even a single day over can mean a ban or refused entry; the engine reports the first breaching day.
Common misconceptions
- "Under 180 days means I'm safe." False — other tests can apply, and the count is only one input.
- "I can chain visits." Each visit is counted alone, but a pattern of back-to-back visits is treated as residence.
- "Arrival day doesn't count." Any part of a day inside is a day inside.
Frequently asked questions
Is the 180-day count per calendar year or rolling?
Each single stay. Each stay is measured on its own.
Do arrival and departure days count?
Yes — any part of a day counts as a day.
