If you want to stay even longer, you'll generally need a residence permit or a long-stay visa arranged in advance — overstaying the tourist window is taken seriously even where entry is easy.
One detail that catches travelers out: Mexico expects your passport to remain valid for 6 months beyond your planned stay. Airlines enforce this at check-in, so a passport expiring soon can end a trip before it starts — check yours before booking.
Overstaying in Mexico — even by a few days — can mean fines, being flagged in the immigration system, and trouble on future entries. Some countries also bar re-entry for a period proportional to the overstay. The safe play is simple: count your days from the entry stamp (not your booking dates), set a reminder a week before your limit, and if plans change, deal with immigration before the deadline rather than after.
Sometimes, but not reliably. Immigration officers can refuse entry if your passport shows back-to-back tourist stays that look like de-facto residence. One or two re-entries per year for genuine trips are normally fine.
Yes — Tourist card (FMM). Arrange it before departure; airlines check at the gate.
Working for a foreign employer while visiting is a legal grey zone in most countries. For anything beyond answering emails on vacation, check the digital nomad visa options for Mexico — many destinations now have a dedicated permit for exactly this.
