My 7 day tourist visa

Funny how some think that good advice is just to ignore the problem until you exit, and the INM agent will just happily wave you on.

For most people who are honestly / mistakenly overstating the permissible # of days (contrasted with the expats living in Mexico improperly on a tourist card) ... declaring the minor overstay is easily remedied. However, for visitors traveling on expired cards who are in vehicles inspected at certain military or police checkpoints ... or otherwise asked to demonstrate permission to be in Mexico ... the consequences can be serious. By the way ... overstay are now recorded in both Mexican and some home country immigration databases

It would be just as easy to tell someone that if they visit Mexico, the consequences can be serious, because believe you me: THEY CAN BE.

As for not having your papers in order, yes, there is a minuscule chance of mild inconvenience if you draw the short straw out of 1,000,000 and get searched at a roadblock or something with an invalid FMM. Overstays, even extensive ones, are remedied through the appropriate administrative procedures. At the border, in the airport? Sure. At the INM building? Hey, even better.

I've always found this issue was somehow related to folks just being really jealous of others who stay for long periods in Mexico (or who visit at all), and lashing out by trying to scare them or wish some kind of crazy punishment on them for their bureaucratic sins. Fortunately, even the new, slightly stricter Mexican guidelines really don't care... it's not a big deal, no matter who wants it to be.

(and for those who are still unclear on the concept, 1) OP did not arrive in "the airport" and 2) 7 days is the standard free transit visa given to thousands of non-flagged people per day)

Concept, what concept?

The OP clearly stated they entered Mexico by bus.

They didn’t enter at Polanco either, but here you are, in Posts 10 & 11, suggesting the Immigration Office in Polanco, while at the same time admonishing those that suggested the Immigration Office in the airport…because the OP didn’t enter at the airport??? Huh?

The previously mentioned Terminal 1 Airport Immigration Office is reportedly open 24/7. They are a full service and fully capable Immigration Office. Very convenient if the OP happens to be passing through CDMX on their trip south.

In CDMX, I stay in the Centro Historico and find the Metro to the airport INM is as quick and easy as to other offices in the city.

"BTW, I'm writing this from my luxury high-rise condo here in Queretaro just minutes from centro. A place it costs you about $1,000 to get to. Enjoy the snow"

Oh I bet you are even very close to the USA owned big box stores that you love so much. I am jealous.....NOT!

I guess some cannot afford to live in their own country.

Yes. And ...

@8, the OP asked if the # of days could be corrected at the Mexico City airport, or elsewhere in the city. The individual will be at the airport arriving in a domestic flight.

If visiting the INM office at the airport is an available option for the OP (as previously suggested it is) I think that's preferable to trying to accomplish the same task at the most often heavily congested Polanco headquarters building.

If the OP chooses the Polanco INM office, I'll suggest stopping afterwards at the popular Caldos D'Leo Restaurante ... nearby on Ejercito Nacional.

Hey, I'd personally follow the, you know, rules, just to avoid being thrown in jail for 20-30 years, but if anyone else wants to try winging it at the airport or finding an INM office in Tepito, they should knock themselves out.

From the official site:
http://www.inm.gob.mx/gobmx/word/index.php/cdmx/

"En Aeropuertos Internacionales sólo se realizan trámites de revisión de documentación migratoria de pasajeros."

I can translate if you need, ya edgy rulebreakers. ;)

...and by the way, even though the "rules" clearly state that the airport is not the place to handle the affairs of terrestrial visitors, I'm sure that a friendly immigration officer might "bend" them as the folks who are suggesting this are so fond of doing. ;)

At the very least, there's a good chance of not being thrown in a dank cell with only tortillas and onions for the rest of the year.

That office took care of me when I was a terrestrial visitor, twice, though both times it was for easy FMM card issues that were quickly taken care of. Since the OP is arriving there on a domestic flight, with an FMM card issue, it should be a snap. Both times I've been to that office there were no lines.

Exactly. Anecdotal evidence (is there any other kind?) seems to show that the system is willing to ignore the technical rules as long as the visitor doesn't seem to be taking it too far... though obviously it's not always guaranteed.

Yes, there was the infamous case of that unlucky German lady and the story of that one Italian dude who sounded like a real character, but these are uncommon, to say the least, and even people who flagrantly abuse the system seem to manage to find a simple $olution in the end.
