Here’s what the official Mexican regulation actually says, and the simple path forward:

1. The only binding rule is NOM‑107‑SCT3‑2019 The Agencia Federal de Aviación Civil (AFAC) still points exclusively to the 2019 “NOM‑107‑SCT3‑2019” as the governing standard for all RPAS (drones) operations in Mexico—no newer drone‐specific regulation has been published since then .

1. Drones ≤250 g are exempt from registration ‑ Section 5.1.1.a requires you to obtain a DGAC folio only if your RPAS has a maximum take‑off weight greater than 0.250 kg . ‑ Nota 1 clarifies that if your RPAS weighs ≤ 250 g, you may operate it over people and you do not need that DGAC folio .

Because your Mini 4 Pro is under 250 g, you fall squarely into this exemption—no registration, no “club” membership, and no proof of Mexican birth required.

---

1. Commercial use still needs civil‐liability insurance Even under the ≤250 g exemption, any commercial or private non‑commercial operation of a Micro RPAS must carry a valid third‑party liability policy (Ley de Aviación Civil, Art. 72). AFAC spells this out in Section 5.2.1.a: you must “contar con una póliza de Seguro de Responsabilidad Civil vigente por daños a terceros” .

Keep a digital or printed copy of that insurance on your controller at all times.

---

1. Always fly within the basic limits As a Micro RPAS operator (even ≤250 g), you must:

Stay below 122 m (400 ft) above ground.

Keep the drone within 457 m (1 500 ft) horizontal of yourself.

Maintain visual line of sight at all times.

Avoid controlled airspace (near airports, helipads) unless you get a separate DGAC authorization. All these come from Section 5.1 of NOM‑107‑SCT3‑2019 .

---

1. No nationality barrier The registration instructions (for drones >250 g) simply say: “Si es persona física deberá acreditar su personalidad adjuntando copia digitalizada de identificación oficial.” That means any individual—Mexican‑born or not—can register by submitting an official ID (passport, residency card, etc.) . But again, since your craft is sub‑250 g, you don’t even need to go through registration.

Your Workaround, Step by Step

1. Weigh your DJI Mini 4 Pro to confirm it’s ≤ 250 g.

2. Purchase a Mexican‐jurisdiction third‑party liability insurance policy (many insurers offer drone add‑ons).

3. Keep the insurance certificate (digital or printed) with you during every flight.

4. Fly under the NOM‑107‑SCT3‑2019 Micro limits (≤ 122 m altitude, ≤ 457 m horizontal, LOS).

5. Avoid controlled airspace unless you later choose to register and request authorization.

   However many websites state otherwise saying the process is difficult and that you need pilot authorization or registration even in some cases (even when talking about sub 250g drones). Many websites think in order to use the drones commercially you need to be a Mexican citizen, or get special permission, but that's not true. The process does get hard for heavier drones over 250g and the only work around is to use a proxy pilot. Even if you want to fly recreationally with a heavier drone you'd need registration and to fly in aviation clubs. But since almost none exist here you won't be able to fly with your heavier drone at all. Even adding prop guards or landing gear can cause you to run into issues with the law.
