Start the canje from your laptop at home, before the flight. Generate the NUT, print the Formato Básico, look at the appointment calendar, and know what you are walking into — because the moment you land in Mérida, Mexico a thirty-calendar-day clock starts, the office that serves you is open four hours a day at one address, and the queue is not visible from outside the system.

That is the verdict. Everything that goes wrong in a foreigner’s first month here goes wrong because this trámite was treated as an errand for week three.

Checked on 2 September 2026.

What the canje is, and why it exists

The visa your consulate put in your passport is not residency. It is a single-entry document, valid 180 days, whose only job is to get you into the country. The Lineamientos generales para la expedición de visas (DOF código 5763837) state the obligation plainly: the holder must

“tramitar dentro de los siguientes 30 días naturales contados a partir de su ingreso al territorio nacional, la tarjeta de residencia que acredite su estancia legal.”

Thirty natural days — calendar days, not working days — counted from the day you enter Mexican territory. Not from the day you reach Mérida, not from the day your shipment arrives, not from the day you find an apartment. From the stamp.

The trámite that turns the visa into a card is expedición de documento migratorio por canje. Everyone here calls it the canje.

Where it happens

INM’s Yucatán office, on INM’s own page checked 2 September 2026:

  • Calle 31 No. 94 por 16 y 20, Col. México, C.P. 97125, Mérida, Yucatán
  • Monday to Friday, 09:00 to 15:00
  • (999) 925 6388 and (999) 925 7487

There are also INM offices in Progreso and Valladolid handling trámites migratorios. If you are settling on the coast, that is worth knowing before you drive into the city.

Four hours a day, five days a week, for the foreign population of a state where — on Segob figures reported locally — the overwhelming majority of Yucatán’s temporary foreign residents live in this one city. Plan accordingly.

The sequence

This is the order it goes in. Steps one to three are doable from anywhere in the world with a printer, and doing them from home is the entire argument of this post.

1. Generate the trámite online and get your NUT. INM’s micrositio de trámites migratorios is where a canje is opened. You capture the trámite and the system issues a NUT — Número Único de Trámite — which is the number everything afterwards is filed under.

2. Save the Formato Básico. Saving the trámite produces a PDF, the Formato Básico, with your NUT printed in the top right corner. Print it. Print a spare. This is the document the counter asks for first.

3. Pay the derechos. Generating the NUT also produces the hojas de ayuda — the payment slips you take to a bank window. Pay before the appointment and keep the stamped receipt; a trámite without proof of payment is a trámite that has not started.

The amount is set by the Ley Federal de Derechos and INM publishes its Tarifas de derechos migratorios 2026, effective 1 January 2026. The increase that year was steep: writing on 13 November 2025 about the Ley Federal de Derechos published in the DOF on 7 November 2025, Clark Hill PLC set out the change as a one-year temporal card going from $5,328 to $11,140.74 pesos, four years from $11,984 to $25,057.82, and the permanent card from $6,494 to $13,578.96 — roughly a doubling. INM publishes its own tariff sheet as an image rather than text, so confirm your own figure against INM’s 2026 tariffs before you pay, and treat any budget written in 2025 as half of what you need.

4. Book the appointment. With the NUT you can look at the calendar. This is the step that decides whether the next month is calm or not.

5. Present the folder. Passport, the entry record, the Formato Básico, the payment receipt, photographs to specification, and whatever your own trámite adds. If the papers are in order the acknowledgement is stamped.

6. Biometrics. Fingerprints, signature and the official photograph are taken before the immigration authority — INM’s own canje guidance is explicit that this happens in person.

7. Collect the card. The resident card comes back with your CURP printed on the front, which is the thing the rest of your life in Mexico is waiting on. What the CURP gates is a longer list than most arrivals expect — the bank account, the phone contract, and a good deal of ordinary administration.

Why you do steps one to three from home

Because the only part of this you cannot control is the calendar, and you want to see it before you are standing inside the deadline.

Nobody can tell you the Mérida wait. I have looked for a published appointment wait for this office and there is not one. The address and the hours are public; the calendar is not, and on 2 September 2026 the public micrositio does not expose available dates until you have a NUT in hand. So every page that tells you “INM Mérida books three weeks out” is telling you about somebody’s experience on a day, which may or may not be your day.

That is precisely why you generate the NUT before you fly. It is the only way to convert an unknown into a number while you still have options — while your dates are movable, while you have not signed a lease, while a week either way costs nothing.

And it is why you do not arrive in the second half of a month with plans. The clock is thirty days and the office is open twenty of them at best.

If the appointment lands past day 30

First, understand what the deadline is attached to: the obligation is to start the trámite within thirty days of entry. A NUT generated and derechos paid inside the window is a different position from having done nothing, and the date on the acknowledgement is the fact you will be discussing.

Second, understand that this is the point where the site’s usual “it’s DIY” advice stops. A missed or nearly-missed canje window is not a paperwork tidy-up. The Lineamientos contemplate consequences for a foreigner whose document position is not regularised, including being required to leave the country. If your appointment lands past day 30, this is the case for paying a gestor or an immigration lawyer, that same week, in Mérida, in person. It is the one moment in the whole residency process where the fee is obviously worth it.

Third: do not fix it by leaving and re-entering. A resident visa is single-entry and you have spent it. Leaving does not reset anything; it removes the only status you have.

What to bring to the counter

Beyond the trámite’s own list, three practical things.

A folder, in order, with copies of everything. Passport, entry record, Formato Básico with the NUT visible, stamped payment receipt, photographs, and a copy of each.

A sentence in Spanish that gets the file looked up, rather than a conversation you cannot follow. “Buenos días. Vengo al trámite de canje. Éste es mi NUT y el comprobante de pago.” Hand over the folder with it. It is enough.

Time. The office runs 09:00 to 15:00 and the trámite may involve more than one visit — presentation, then the biometrics call. Do not book anything else for that morning, and do not book anything for the following morning either.

Where this sits in the first month

The canje is first. Not first among equals — first.

The card carries the CURP; the CURP opens the bank account; the bank account ends the foreign-ATM tax on your monthly budget; the card is what a landlord with a póliza jurídica wants to see; and residency is what opens IMSS voluntary affiliation. Do it in any other order and you will run the same loop twice.

The first-week sequence lays the whole order out. This post is the item at the top of it.

Where to check this

  • The 30-day rule: DOF código 5763837, and SRE’s own temporary residence visa page, which states the same obligation.
  • The office, hours and phones: INM’s Yucatán page.
  • The trámite, the NUT and the Formato Básico: INM’s micrositio de trámites migratorios.
  • The fee: INM’s tarifas de derechos migratorios for the current year — and check it at the counter.

Nothing here is immigration advice, and I am describing what applicants are asked for, not what any office is obliged to do on your date. The deadline, though, is not discretionary, and it starts the day you land.
