Reports from travelers and immigration attorneys are raising flags for anyone planning a trip to Mexico: airport officers are increasingly granting tourist permits for far fewer than the standard 180 days, and some say U.S.-Mexico tensions are feeding into that dynamic.
Sonia Diaz, a licensed immigration attorney who practices in San Miguel de Allende, Puerto Vallarta, and Nayarit, recently posted a warning on social media that has been circulating widely among expats and travelers. She described receiving regular messages from visitors who arrive in Mexico only to find their tourist permit stamped with as few as 10 days — a number that cannot be changed once issued.
“Weekly, I receive similar emails,” Diaz wrote.
Officer Discretion Is the Rule, Not the Exception
Under Mexico’s immigration law, specifically Article 43 of the Ley de Migración, the number of days written on a tourist permit — known as the Forma Migratoria Múltiple, or FMM — is entirely at the discretion of the officer on duty. The maximum is 180 days, but there is no floor. Officers may ask about travel plans, return flights, and accommodation, and they factor those answers into the number they stamp.
That process has always existed. What is changing, according to Diaz and travelers reporting similar experiences, is the frequency with which officers are issuing far shorter stays than normal — and the airports where this is happening. This is not limited to any single entry point. Diaz was emphatic: it is happening across all airports, including those with automated passport scanners.
Once the stamp is in your passport, the duration is final. There is no extension process available inside Mexico. If a traveler finds their return flight falls outside the allotted window, they face either paying an overstay fine or leaving Mexico early and re-entering on a new permit — assuming they can get a longer one on the next try.
A Political Climate That Is Reaching Airport Counters
Diaz points to the broader bilateral friction as a contributing factor in how some officers are making decisions. With the Trump administration reviewing all 53 Mexican consulates in the United States for potential closure — a move reported this month by CBS News and the Associated Press — resentment is running in both directions. Mexicans seeking a U.S. tourist visa currently face a roughly two-year wait and a fee of around MX$4,200 (about US$230), with no guarantee of approval.
There is also the question of what happens to travelers who already hold a canje stamp in their passport, indicating they are in the process of obtaining Mexican residency. Diaz noted that some officers are logging those individuals as ordinary tourists rather than recording their correct immigration status — a potentially serious error that could complicate the residency process.
“Immigration staff at airports have a lot of independence,” Diaz wrote. “They also have their personal beliefs and politics.”
What Travelers and Prospective Residents Should Know
For anyone traveling to Mexico as a tourist, immigration attorneys recommend arriving prepared. Have a printed or digital copy of your return ticket, hotel reservation, and a clear explanation of your itinerary ready before you reach the officer’s window. Be direct and polite about how long you intend to stay. Check the number in your passport stamp before leaving the immigration hall — you are entitled to know what was entered, and catching an error while still in the area gives you the best chance of resolving it.
For those in the middle of the residency process — the canje stage, where a consulate-approved visa is being exchanged for a resident card — the stakes are even higher. Diaz and other immigration professionals have repeatedly advised those travelers to make clear at the counter that they are entering under a canje, not as tourists, and to confirm that the officer records their status correctly.
Travelers who find themselves stranded with a very short permit and a return flight weeks away should seek legal counsel immediately. A qualified immigration attorney can sometimes find options depending on the specific circumstances, though there is no guaranteed remedy once the stamp is set.

FMM Quick Facts
- The FMM (Forma Migratoria Múltiple) is a required entry permit, not a visa, for tourists and business visitors from the U.S., Canada, and other no-visa countries
- Maximum authorized stay: 180 days — but the actual number is set by the officer at the counter
- Once stamped, the number of days cannot be extended from inside Mexico
- The 2026 FMM fee is MX$983 (about US$54), usually included in airfare; free for stays of 7 days or fewer
- Always check your passport stamp before leaving the immigration hall
- Travelers in the canje process must tell the officer they are not entering as tourists and confirm their status is recorded correctly
- Those who overstay their permit face a fine before departure and possible re-entry complications
