Employer obligations when hiring foreigners in Mexico: the INM employer certificate, verification visits, reporting duties and sanctions

Last verified: 2026-10-26 · Status: Stable

Any individual or company that hires a foreigner or makes a job offer to one must first obtain an employer registration certificate (constancia de inscripción del empleador) from the National Migration Institute (INM), for a 2026 fee of MXN 391. The certificate replaces proof of legal existence and powers in later filings, must list every branch where foreigners work, must be updated within 30 days of a change of address or legal representative, and the proof of the last tax return must be refreshed each year. INM may visit employers to verify job offers, foreign staff must prove their status when asked, residents must report a new workplace within 90 days, and companies must also respect the 90 percent Mexican workforce rule and register foreign staff with IMSS like any worker.

The rule

1. The employer registration certificate. Individuals and companies that hire foreign staff or issue a job offer to a foreigner must obtain the certificate from INM. A company files the application with its articles of incorporation and amendments, the deed granting powers to its legal representatives (if not in the articles), the representative's official ID, proof of the company's address issued within the previous 30 days, its RFC tax registration certificate and an official record of its latest tax return, and a list of employees and their nationalities. An individual employer files an official ID, recent proof of address, RFC certificate and latest tax return record. The employer must register its tax address and every branch or office where foreigners work, with the data of each branch representative. In later filings as offeror, the employer only shows the updated certificate to prove legal personality and powers.
Cost to do it: Obtain or update the certificate: MXN 391 (USD 20.95) under LFD art. 13 section V (Annex 4 rounded amount). Notary or legal fees for the powers of attorney are market priced and not regulated.
Example: A newly incorporated S.A. de C.V. in Monterrey that wants to bring a foreign controller first obtains its RFC and files its first tax return, then applies for the INM certificate with the deed, powers, representative ID, a utility bill under 30 days old and the employee list. / Certificate fee about USD 21 at 18.6638.Reglamento de la Ley de Migración, DOF 28 September 2012 (Chamber of Deputies consolidated text, last reform DOF 23 May 2014); Ley Federal de Derechos (Chamber of Deputies consolidated text, last reform DOF 7 November 2025); Annex 4 of the Resolución Miscelánea Fiscal para 2026, DOF 28 December 2025, Reglamento art. 166; LFD art. 13 section V, 2012-09-28 official text · verified 2026-10-26

2. Keeping the certificate current. Employers must notify INM within 30 calendar days of any change of address or of legal representative or attorney in fact, attaching the public deeds, and must update every year the record of the latest tax return. A temporary residence based on a job offer, a visitor condition with permission for paid activities, a border worker condition and any work permit for a temporary resident all require a job offer that cites the certificate data.
Cost to do it: Each update: MXN 391 (USD 20.95) (LFD art. 13 section V).
Example: A company that moves its head office from Mexico City to Querétaro in March files the change with INM before the end of the 30 day window, so that job offers filed afterwards match the certificate. / About USD 21 per update at 18.6638.Reglamento de la Ley de Migración, DOF 28 September 2012 (Chamber of Deputies consolidated text, last reform DOF 23 May 2014), Reglamento arts. 131, 134, 138 section II, 165 and 166, 2012-09-28 official text · verified 2026-10-26

3. Verification visits and proof of status. INM carries out verification visits ex officio to confirm data given in migration filings, when a foreigner's authorized stay appears to have expired, or to obtain information needed to apply the law, under a written order that names the officials, place, purpose and scope. In job offer cases INM may visit to confirm the offer and the existence of the employer. Foreigners must prove their regular migration status when INM requires it. Separately, immigration documents do not authorize regulated activities; when another authority finds a foreigner working without a required licence or authorization, it asks INM to open the corresponding migration procedure.
Cost to do it: No fee. The practical cost is keeping each foreign employee's card, permit and job offer on file at the workplace.
Example: During a verification visit at a manufacturing plant, INM officials ask a foreign technician for proof of status; the HR file shows the temporary resident card with work permission and the job offer citing the plant's certificate. / Not applicable.Ley de Migración, DOF 25 May 2011 (Chamber of Deputies consolidated text, last reform DOF 15 January 2026); Reglamento de la Ley de Migración, DOF 28 September 2012 (Chamber of Deputies consolidated text, last reform DOF 23 May 2014), Ley de Migración arts. 92 and 94; Reglamento arts. 115, 140, 165 section II and 168, 2011-05-25 official text · verified 2026-10-26

4. Reporting duties of foreign staff and related fines. Temporary and permanent residents must report to INM any change of civil status, nationality, address or place of work within 90 days. Late or missing reports carry a fine of 20 to 100 days of minimum wage, read as UMA since the 2016 deindexation reform. A residence card used for activities other than those its condition allows is cancelled. Anyone who, without being a competent authority, retains a foreigner's identity or migration documents without the holder's authorization faces a fine of 1,000 to 10,000 days, so employers should not hold passports or residence cards.
Cost to do it: Late report fine: 20 to 100 UMA, MXN 2,346.20 to MXN 11,731 (USD 126 to USD 629). Retaining documents: 1,000 to 10,000 UMA, MXN 117,310 to MXN 1,173,100 (USD 6,285 to USD 62,854), at the 2026 UMA of MXN 117.31.
Example: A foreign manager transferred from the Guadalajara branch to the Mexico City head office has 90 days to report the new place of work; HR diarises the deadline and keeps a copy of the filing. / Late report fine about USD 126 to USD 629; document retention fine about USD 6,285 to USD 62,853 at 18.6638.Ley de Migración, DOF 25 May 2011 (Chamber of Deputies consolidated text, last reform DOF 15 January 2026); Reglamento de la Ley de Migración, DOF 28 September 2012 (Chamber of Deputies consolidated text, last reform DOF 23 May 2014), Ley de Migración arts. 63, 147 and 158; Reglamento arts. 163 section IV and 167, 2011-05-25 official text · verified 2026-10-26

5. Mexican workforce share and social security registration. Employers must keep at least 90 percent Mexican workers in each company or establishment, with foreign technical and professional staff limited to 10 percent of the specialty and subject to joint training duties; directors, administrators and general managers are excluded. Foreign workers in a subordinate employment relationship are compulsory insured persons under the Social Security Law like any other worker, whatever the nature of the employer.
Cost to do it: Employer social security contributions on the foreign worker's wages, as for Mexican staff (see the labor social security page).
Example: A 30 employee services company with a foreign general manager may still hire up to 3 other foreign workers, each registered with IMSS from the first day of work. / Not applicable.Ley Federal del Trabajo (consolidated text, last reform DOF 14 May 2026); Ley del Seguro Social (consolidated text, last reform DOF 15 January 2026), LFT art. 7; LSS art. 12 section I, 1970-04-01 official text · verified 2026-10-26

Worked example

A US owned distribution company in Mexico City with 80 employees plans to hire two foreign specialists in 2027.
It obtains the INM certificate (MXN 391, about USD 21) with its deed, powers, RFC certificate and 2025 annual return record, listing its warehouse in Estado de México as a branch where one specialist will work.
Both job offers cite the certificate, so each specialist's residence card fee is halved. When the company changes its legal representative in May 2027, it updates the certificate within 30 days (another MXN 391).
With 80 employees it may employ up to 8 foreign workers outside director and general manager roles, so the two hires fit.

Step by step

1. Obtain the RFC, file at least one tax return and gather the deed, powers and representative ID.
2. Apply for the INM employer certificate, listing every branch where foreign staff will work.
3. Build an HR file per foreign employee: card, work permission wording, job offer, CURP, IMSS registration and any professional licence.
4. Diarise renewal windows (30 days before card expiry) and change reports (90 days for workers, 30 days for the employer).
5. Update the certificate's tax return record every year and before filing new job offers.
6. Never retain employees' passports or residence cards; take copies instead.

Common traps

Filing a job offer before the certificate exists. Job offer visas, paid visitor conditions and work permits all require the certificate data (Reglamento arts. 115, 131 and 165).
Forgetting branches. Every address where foreigners work must be registered with the certificate (Reglamento art. 166).
Holding staff documents. Retaining a foreigner's identity or migration documents without the holder's authorization, without being a competent authority, carries a fine of 1,000 to 10,000 UMA (Ley de Migración art. 147).
Assuming licensing follows the visa. Immigration documents do not authorize regulated professions; the employer must check that licences exist (Reglamento art. 140).
Skipping IMSS for foreign staff. Foreign employees in a subordinate relationship are compulsory insured persons (LSS art. 12).
