Employment Contract for Foreign Worker Mexico (Contrato de Trabajo para Extranjero)

An Employment Contract for Foreign Worker Mexico (Contrato de Trabajo para Extranjero) is a formal written employment agreement between a Mexican employer (patrón) and a foreign national employee (trabajador extranjero) who holds valid work authorisation in Mexico. The agreement is governed by the Ley Federal del Trabajo (LFT), which applies in full to all workers performing services in Mexican territory regardless of nationality under LFT Article 2, and by the Ley de Migración (published 25 May 2011) which governs the immigration status, visa categories, and work authorisation requirements applicable to foreign workers.

LFT Article 7 establishes the foreign worker ratio rule (regla de proporción de trabajadores extranjeros): Mexican employers may not employ more than 10% of their workforce as foreign technical workers (técnicos y profesionales extranjeros) and 10% as non-technical (trabajadores no especializados), subject to exceptions for enterprises with fewer than 10 employees or where no suitably qualified Mexican workers exist for a specialised position. Violations of the Article 7 ratio expose the employer to fines by the Secretaría del Trabajo y Previsión Social (STPS) and potential cancellation of the foreign worker's visa authorisation by the Instituto Nacional de Migración (INM).

The Ley de Migración Article 52 establishes the visa and residency categories under which foreign nationals may legally work in Mexico. The principal work-authorisation categories are: Residente Temporal con permiso de trabajo (Temporary Resident with work permit) — valid for up to four years, renewable — for foreign workers sponsored by a Mexican employer; Residente Permanente (Permanent Resident) — who may work without restriction for any employer in Mexico; and Visitante con permiso para realizar actividades remuneradas (Visitor with paid activity permit) — for temporary assignments not exceeding 180 days. The employer must verify the foreign worker's valid immigration document (Tarjeta de Residencia or visa with work authorisation notation) and retain a copy before commencing employment. Employing a foreign national without valid work authorisation exposes the employer to fines of 100 to 10,000 UMAS under Ley de Migración Article 161 and potential cancellation of the employer's INM employer registration (clave de empleador).

All foreign workers employed in Mexico must obtain a Clave Única de Registro de Población (CURP) — the national identity code issued by the RENAPO (Registro Nacional de Población) — which serves as the worker's tax and social security identifier. The employer must register the foreign worker with the Instituto Mexicano del Seguro Social (IMSS) and make social security contributions at the same rates applicable to Mexican workers, regardless of the worker's nationality. The employer must also register the worker with the SAT for income tax withholding (retención de ISR) and issue monthly CFDI payroll receipts (recibos de nómina digitales) as required by the Código Fiscal de la Federación Article 29-A.

The Ley de Migración Article 57 imposes an obligation on employers of foreign workers to notify the INM within 10 business days of changes in the foreign worker's employment conditions (salary, position, work location) or termination of employment. Failure to notify may result in administrative fines and complications in the renewal of the foreign worker's Tarjeta de Residencia. Employment contracts for foreign workers must specify the salary in Mexican pesos (MXN) — foreign currency salary clauses are permissible but the MXN equivalent must be stated — and must comply with all LFT minimum standards including the Salario Mínimo General (SMG) set by the Comisión Nacional de Salarios Mínimos (CONASAMI).

An Employment Contract for Foreign Worker Mexico is required whenever a Mexican employer hires a foreign national to perform services in Mexico under an employment relationship (relación laboral).

International corporate assignments: Multinational companies seconding executives (directivos), technical specialists, or project managers from foreign subsidiaries to their Mexican operations must document the local Mexican employment relationship in compliance with LFT and Ley de Migración. The contract is required both for the INM visa application and for the SAT to determine whether the foreign worker's income is taxable in Mexico under the Ley del Impuesto sobre la Renta (LISR) Articles 1 and 9.

Specialised technical recruitment: When Mexican companies recruit foreign engineers, IT specialists, healthcare professionals, or other technical workers for positions where no qualified Mexican candidates are available, LFT Article 7 permits hiring up to 10% of the technical workforce as foreigners. The employment contract is the primary evidence submitted to the INM to support the Residente Temporal con permiso de trabajo visa application.

Academic and research institutions: Universities (universidades), research centres (centros de investigación), and cultural institutions affiliated with the Consejo Nacional de Humanidades, Ciencias y Tecnologías (CONAHCYT) frequently employ foreign researchers and professors. These institutions must document employment under the LFT and Ley de Migración even when the foreign worker enters under a student or research visa that includes work authorisation.

Maquiladora and manufacturing sector: Foreign workers employed in maquiladora operations under the IMMEX programme (Industria Manufacturera, Maquiladora y de Servicios de Exportación) must have formalised employment contracts compliant with both LFT and the specific immigration provisions applicable to the industrial sector under the Ley de Migración. The STPS and INM conduct joint audits (visitas de inspección conjunta) in IMMEX facilities to verify that foreign technical supervisors and engineers are properly documented.

Hospitality, tourism, and entertainment sector: Hotels (cadenas hoteleras), resorts, cruise operators, and entertainment companies frequently employ foreign chefs, performers, sports instructors, and management personnel. Under LFT Article 7 exceptions for specialised roles, the employment contract must document why no qualified Mexican candidate was available and must accompany the INM employer authorisation request. STPS labour inspectors routinely verify LFT Article 7 compliance in hotels and hospitality chains.

IMSS and INM compliance audits: The IMSS and the INM conduct periodic workplace audits (visitas de verificación) in which they verify that all foreign workers are properly registered under IMSS and hold valid work authorisation. A written employment contract is the first document requested in these audits and is required to confirm the validity of the foreign worker's immigration status, salary, and job classification.

A valid Employment Contract for Foreign Worker Mexico under the Ley Federal del Trabajo and Ley de Migración must include the following essential elements.

Identification of Parties: Full legal name, RFC, and domicile of the employer (patrón), and full legal name, passport number, nationality, CURP, and immigration document details (Tarjeta de Residencia number, visa type, INM authorisation reference) of the foreign worker. The employer's INM employer registration number (clave de empleador ante el INM) should be referenced.

Immigration Status Verification: Statement of the foreign worker's immigration authorisation category under Ley de Migración Article 52 — Residente Temporal con permiso de trabajo, Residente Permanente, or Visitante con permiso para actividades remuneradas — with the document number, issue date, and expiry date. The employer's obligation to retain copies of the valid immigration document and to notify the INM of employment changes within 10 business days under Article 57 Ley de Migración.

Position and Duties: Job title (puesto), department (área), work location (lugar de trabajo), and detailed description of duties and responsibilities in the Mexican operation. Reference to LFT Article 7 compliance — confirming that the foreign worker's position falls within the permitted 10% technical worker ratio or within an applicable exception.

Salary and Benefits: Monthly or weekly salary expressed in Mexican pesos (MXN) — minimum equal to the Salario Mínimo General established by CONASAMI. Mandatory LFT benefits: aguinaldo (Christmas bonus — minimum 15 days salary under LFT Article 87), vacaciones (vacation days — minimum 12 days for the first year under LFT Article 76 as amended in 2023), prima vacacional (vacation premium — 25% of vacation salary under Article 80), and participation in Reparto de Utilidades (PTU profit sharing) where applicable under LFT Article 117.

Working Hours and Schedule: Hours per week (maximum 48 hours for day shift — LFT Article 61; 42 hours for night shift; 45 hours for mixed shift) and weekly rest day under LFT Article 69. Overtime compensation at 200% of regular hourly rate for the first 9 hours per week and 300% thereafter under LFT Article 68.

IMSS and Tax Obligations: Employer's obligation to register the foreign worker with IMSS and make social security contributions (cuotas patronales) covering Seguro de Enfermedades y Maternidad, Seguro de Invalidez y Vida, Seguro de Retiro (AFORE), Seguro de Riesgos de Trabajo, and INFONAVIT contributions, all at the same rates applicable to Mexican workers. SAT withholding obligations for ISR on employment income under LISR Articles 94–99, including the obligation to issue monthly CFDI nómina receipts via a PAC (Proveedor Autorizado de Certificación) registered with the SAT.

Confidentiality and Intellectual Property: If the foreign worker will have access to the employer's confidential information, trade secrets (secretos industriales) protected under the Ley Federal de Protección a la Propiedad Industrial (LFPPI) Articles 163–169, or proprietary software, the employment contract should include a confidentiality and IP assignment clause. Under LFT Article 163, inventions made by an employee using the employer's resources and facilities belong to the employer, with the worker entitled to additional compensation if the invention has exceptional commercial value beyond the worker's normal duties.

Termination and Severance: The applicable termination provisions under LFT Articles 46–52 — the grounds for justified dismissal (rescisión justificada) that do not give rise to severance, and the employer's obligation to pay the full constitutional indemnification (indemnización constitucional) of three months salary plus 20 days per year of service for unjustified dismissal. For foreign workers on fixed-term contracts tied to specific projects (obras determinadas), the contract should specify whether expiry constitutes justified termination or triggers proportional severance obligations under LFT Article 53. The INM must be notified of the termination within 10 business days under Ley de Migración Article 57 regardless of the grounds for termination.
