INM Denials and Appeals: Immigration Defense in Mexico.

In short

If Mexico's National Migration Institute (INM) denies an application, leaves it unanswered, imposes a fine or orders something that looks wrong, there are legal remedies: administrative review (recurso de revisión), a nullity suit before the Federal Administrative Court (TFJA) and amparo. Deadlines are short, so the first priority is not to let days slip by.

Is this for you?

  • The INM notified you of a denial of residency, renewal, change of status or work permit.
  • Your application has gone a long time without an answer and you do not know what to do.
  • You were hit with a fine or an administrative immigration proceeding.
  • A facilitator told you 'there is nothing left to do' and you want a second opinion.

General requirements

The INM decision or official letter
The document that records the denial, fine or order. It is the foundation of everything: the deadlines and the grounds to challenge come from it.
The date you were notified
Deadlines to challenge run from notification. We need to know when and how you were notified, because that determines how much time is left.
Your application file
The application, receipts, documents you submitted and any communication with the INM. From these we identify what went wrong and whether the INM made a mistake.
ID and contact details
Passport, immigration card or proof of your current situation, so filings can be made on your behalf.
Power of attorney or authorization
To act for you before the INM, the TFJA or a federal district court, representation is formalized under each forum's rules.
Evidence to support your case
Additional documents, certificates or proof that were not weighed and that help show you meet the requirements.

Deadlines and routes change depending on the type of INM act and the date of notification. Do not wait for the consultation to look at your decision: the earlier it is reviewed, the more options remain.

Step-by-step process

  1. Step 1: Review the decision and deadlines

    First we identify what the act is, when it was notified and how many days remain. If time is very short, the fastest route takes priority.

  2. Step 2: Choose the defense route

    We weigh administrative review before the same authority, a nullity suit before the TFJA and amparo, depending on the type of act, the risk and what you want to achieve. The same route is not always the best one.

  3. Step 3: Prepare and file the remedy

    We draft and file the brief with the legal arguments, the evidence and, when appropriate, a request for suspension or protective measures.

  4. Step 4: Follow the proceeding

    We handle requests, hearings and deadlines until the authority or court decides.

  5. Step 5: Compliance and next plan

    If the outcome is favorable, we monitor that the INM complies. If not, we review the next stages and alternatives, including a new application built on better preparation.

Estimated timelines

Estimated timelines
Deadline to challenge Short: generally between 15 and 30 business days depending on the route and the act, counted from notification.
Administrative review Usually resolved in weeks to a couple of months, though it depends on the authority.
Nullity suit or amparo These are court proceedings: they can take several months or more than a year, depending on the forum and its caseload.

Common mistakes

  • Letting days pass while thinking about 'trying again' instead of checking whether the denial could be challenged.
  • Refiling the same application without correcting the reason for the denial.
  • Losing the notification or not knowing what date it was made, which is what sets the deadline.
  • Believing the only option is to 'ask again' and that no remedies exist.
  • Relying on an intermediary who cannot sign or litigate a remedy, and missing the deadline.

Questions about this process

What is the difference between administrative review, a nullity suit and amparo?
Administrative review is filed with the same authority so it reexamines its own decision. A nullity suit is filed before the TFJA, a federal court that checks whether the act was lawful. Amparo is filed before a federal court when rights protected by the Constitution are affected. Each has its own requirements and deadlines.
How long do I have to challenge?
Deadlines are short and counted in business days from notification. They vary by route, generally between 15 and 30 business days. That is why it is important to review your case right away.
Can I stay in Mexico while I challenge?
It depends on the act and on whether a suspension or protective measure is obtained. It is not automatic. We review your situation and what can be requested in each case.
Can a facilitator file these remedies?
Appeals, suits and amparo are legal actions that normally require a licensed lawyer with a professional license (cédula profesional). A facilitator can help with paperwork but is not authorized to litigate.
Does challenging mean I will get approved?
No. A remedy seeks a review of the decision and, if there was an error, a correction. The outcome depends on the facts, the documents and the view of the authority or court. What we do is give you a clear read of your chances before you start.
