Business Visitor Visa Invitation Letter Mexico (Carta de Invitación de Negocios)

A Business Visitor Visa Invitation Letter Mexico (Carta de Invitación de Negocios) is a formal document issued by a Mexican company, institution, or individual inviting a foreign national to visit Mexico for business purposes, supporting the visitor's visa application at a Mexican embassy or consulate abroad or their entry request at a Mexican port of entry administered by the Instituto Nacional de Migración (INM). The document is used in the context of the Ley de Migración (published in the DOF on 25 May 2011) and its Reglamento (RLMIGR), which establish the legal framework for all migratory categories in Mexico.

Under Ley de Migración Article 40 fracción I, foreign nationals entering Mexico for business activities — including attending meetings, negotiations, training sessions, conferences, trade fairs (ferias comerciales), or fact-finding visits — may enter under the visitante sin permiso para realizar actividades lucrativas category (business visitor without work permit) if their activities do not constitute the direct provision of paid services to a Mexican entity. Foreign nationals who will receive remuneration from a Mexican source for services rendered in Mexican territory require a different migratory category — visitante con permiso para realizar actividades lucrativas — under Ley de Migración Article 40 fracción II.

The carta de invitación de negocios is not a visa in itself — it is a supporting document that substantiates the purpose and legitimacy of the visit for the reviewing consular officer or INM border official. Mexican embassies and consulates abroad review the invitation letter as part of the visa application package to assess whether the applicant's stated business purpose is credible, whether the inviting Mexican entity is legally constituted and active (registered in the Registro Público de Comercio and with active RFC before the SAT), and whether the visitor is likely to return to their country of residence after the visit.

The Secretaría de Relaciones Exteriores (SRE), through its consular network, processes visa applications for foreign nationals requiring a visa to enter Mexico — nationals of countries that do not have visa exemption agreements with Mexico must obtain a Mexican visa before travel. The Acuerdo por el que se establece la lista de países cuyos nacionales requieren visa para ingresar a México (updated periodically by SRE) determines which nationalities require a Mexican visa. The INM, operating under the Secretaría de Gobernación (SEGOB), controls the actual entry and controls the 180-day maximum stay for visitantes under Ley de Migración Article 52.

For business visitors from countries with diplomatic or commercial ties with Mexico, the carta de invitación de negocios from a legitimate Mexican host company significantly strengthens the visa application. The inviting company's RFC registration with the SAT, its Registro Público de Comercio entry, and its track record of previous valid business invitations all support the credibility of the invitation. Mexican companies should maintain a register of business invitations issued to foreign visitors as part of their compliance obligations under the Ley Federal para la Prevención e Identificación de Operaciones con Recursos de Procedencia Ilícita (LFPIORPI — anti-money laundering law).

A Business Visitor Visa Invitation Letter Mexico is needed whenever a Mexican company or individual invites a foreign national to visit Mexico for business purposes and the visitor requires documentary support for their visa application or INM entry process.

The letter is required when a foreign client, supplier, partner, investor, or counterparty from a country that requires a Mexican visa needs to attend meetings, contract negotiations, site inspections, due diligence visits, or product demonstrations at the Mexican host company's facilities. The inviting company must provide the carta de invitación to substantiate the business purpose before the SRE consular officer.

The document is needed when a foreign national from a visa-exempt country — who does not need a visa before travel — is asked by an INM border official at a Mexican port of entry to demonstrate the nature and legitimacy of their business visit. Although visa-exempt nationals may enter without prior visa processing, INM border agents retain discretion to request supporting documentation under Ley de Migración Article 88, and a carta de invitación significantly reduces risk of entry denial.

The letter is required when a multinational corporation sends an employee from a foreign affiliate to visit the Mexican subsidiary for training, knowledge transfer, project review, or corporate governance activities — even intra-group visits require proper immigration documentation to avoid reclassification as undocumented work under Ley de Migración Article 159 (migratory violations by employers).

The carta de invitación de negocios is also needed when a foreign academic, researcher, or professional attends a conference, trade fair (like Expo ANTAD in Guadalajara or Expo ManufacturaTec in Monterrey), or technical symposium hosted by a Mexican organisation — the inviting organisation should issue the letter and confirm the professional or non-lucrative nature of the activity.

Under Ley de Migración Article 40 and the RLMIGR Articles 62–70, the maximum permitted stay for a visitante sin permiso para realizar actividades lucrativas is 180 days, non-extendable within the same migratory year — the carta de invitación should specify the expected duration of the visit and confirm it falls within the legally permitted period.

The carta de invitacion de negocios is also required when a Mexican company sponsors a foreign supplier's factory audit visit — particularly in manufacturing sectors under the IMMEX (Industria Manufacturera, Maquiladora y de Servicios de Exportacion) programme, where foreign principal companies send compliance auditors to verify Mexican contract manufacturers' quality and labour standards. The INM-registered IMMEX company's invitation letter confirms the audit's legitimate business purpose and the auditor's non-lucrative visitante status under Ley de Migracion Article 40 fraccion I.

A valid Business Visitor Visa Invitation Letter Mexico under Ley de Migración Article 40 must contain the following essential elements to satisfy INM and consular requirements:

Inviting Entity Identification: Full legal name (razón social) of the Mexican company or individual issuing the invitation; RFC (Registro Federal de Contribuyentes) as registered with SAT; full registered address; telephone and email contact; and the name and title of the authorised signatory. The inviting company's active RFC status can be verified through the SAT portal — consular officers routinely perform this verification.

Invited Person Identification: Full name as it appears in the foreign national's passport; passport number, issuing country, and expiry date; nationality; date of birth; occupation and employer (if applicable); country of residence; and email contact. The invitation must match the passport details exactly to avoid processing delays.

Purpose and Nature of Visit: A clear, specific description of the business activities to be conducted — for example, negotiating a supply agreement, attending the quarterly board meeting, inspecting manufacturing facilities, participating in a technical training programme, or closing a commercial transaction. The letter should confirm that the visit is for business consultation, negotiation, or observation purposes only, and does not involve the direct performance of paid services in Mexican territory.

Dates of Visit: Proposed arrival and departure dates, or the expected duration of the visit (e.g., five business days, two weeks). The total planned stay must not exceed 180 days under Ley de Migración Article 52. For visa applications, the proposed travel dates should be consistent with the visa validity period requested.

Financial Responsibility Declaration: A statement confirming who will bear the costs of the visit — whether the inviting Mexican entity covers accommodation, transportation, and per diem expenses, or whether the visitor self-funds the visit. This declaration is reviewed by consular officers to assess the visitor's intent to depart Mexico after the visit.

No Employment Relationship Confirmation: An explicit statement that the foreign visitor will not receive remuneration from a Mexican source for services rendered in Mexico, will not be in a subordinate employment relationship (relación laboral) with a Mexican entity, and will not perform activities requiring a work permit under Ley de Migración Article 40 fracción II or the Ley Federal del Trabajo.

Inviting Company Credibility Markers: Reference to the company's years of operation in Mexico, its RFC registration date, its Registro Público de Comercio folio, and any relevant certifications (e.g., IMMEX maquiladora programme registration, PROSEC authorisation, OEA certification) — these elements strengthen the letter's credibility with consular officials and INM.

Signature and Company Seal: Handwritten signature of the authorised representative (representante legal) of the inviting entity, company seal (sello empresarial) if available, and the date and place of issuance. For small businesses, a notarised letter (carta notariada) significantly increases acceptance rates at consulates.

Compliance with LFPIORPI: Mexican companies that regularly issue business invitation letters should maintain a register of invitations as part of their anti-money-laundering compliance obligations under the Ley Federal para la Prevencion e Identificacion de Operaciones con Recursos de Procedencia Ilicita (LFPIORPI). Invitations to high-risk jurisdictions or for large-value commercial transactions may require enhanced due diligence documentation under LFPIORPI Article 17.
