If you’re planning a trip to Mexico, you might have heard that tourists can get up to 180 days in the country. While that’s true, what you actually get depends on the immigration officer processing your entry—and it’s not always the maximum stay. Based on my experience and my boyfriend’s, here’s what you should know before arriving in Mexico to avoid any issues at immigration.

Entering Mexico Without a Return Ticket? Read This First

I flew into Mérida with my U.S. passport and didn’t have a return flight booked. That turned out to be a mistake because the immigration officer only gave me 50 days. Unlike some other countries, Mexico does not allow you to extend your stay once you’re in the country. That means if you want more time, you’d have to exit and re-enter—which is an extra hassle and expense.

To avoid this, I highly recommend booking a return ticket before you arrive. If you’re not sure when you’ll actually leave, there’s a simple solution: book a refundable flight. Airlines like American Airlines and Avianca allow you to purchase tickets that you can cancel for a refund. Just be careful—Avianca only allows refunds on their flexible tickets, not basic fares. And remember to cancel within the 24-hour window!

How Immigration Officers Decide Your Stay Duration

My boyfriend, who flew into Cancún from Bogotá with his Colombian passport, had a different experience. Since I had already entered Mexico, we made sure he had a return flight booked before his arrival. The immigration officer asked him tons of questions—where he was staying, how long, and proof of funds. In the end, he got 65 days, exactly the number of days until his return flight.

Want 180 Days? Here’s the Trick

Unlike some countries that automatically give tourists 90 or 180 days, Mexico bases your stay on your return ticket. If you want the full 180 days, book a flight that’s exactly 180 days out. This doesn’t guarantee you’ll get it, but it increases your chances. If you book a return flight for three months later, don’t be surprised if they only give you 90 days.

Other Things to Keep in Mind

• Proof of Accommodation & Funds – Some officers might ask for proof of where you’ll be staying (hotel booking or an address) and evidence that you can support yourself financially during your trip.
• Entry Form (FMM) & Digital Check-In – Some airports are now paperless, but you might still get a Forma Migratoria Múltiple (FMM) upon arrival. Always keep a copy, as you might need it when leaving.
• Airport Matters – Some airports, like Cancún, are known for stricter questioning. Be prepared for additional scrutiny if entering through major tourist hubs.

Final Thoughts

Mexico is a fantastic place to visit, but its tourist entry rules have become stricter in recent years. Don’t assume you’ll get 180 days automatically—immigration officers make decisions based on your flight details and other factors. Booking a return ticket (even a refundable one) is the best way to ensure you get the time you need.
