Bringing Foreign Staff to Argentina: Sponsorship, Residence and the 2025 Reform

Sending an executive to run the Argentine operation, or bringing in a specialist the local market cannot supply, involves a step foreign companies rarely anticipate: the employer has to register first.

In Argentina the immigration process for a contracted worker does not begin with the worker. It begins with the company, and a company that is not registered cannot sponsor anyone.

The framework

Immigration is governed by the Migration Act and its implementing decree, both substantially amended by Emergency Decree 366/2025, published on 29 May 2025. Foreign nationals are admitted as permanent, temporary or transitory residents, and the national migration authority determines whether a change of category is available.

For a company bringing in staff, the relevant route is temporary residence as a contracted worker.

The employer’s registration comes first

Any individual or legal entity in Argentina that requests the admission or residence of a foreign national under the relevant categories must be registered in the national registry of sponsors of foreign nationals, maintained by the migration authority. Without a current registration, neither the migration authority nor Argentine consulates abroad will process the application.

Registration is a substantive control, not a form. Sponsors are required to post security, which may be real or by sworn undertaking, within a range set by reference to statutory minimum wages. In practice the authority inspects the company’s commercial premises before granting registration, to verify that the business exists and that there is a genuine vacancy requiring foreign labour.

Sponsors carry continuing obligations. Non-compliance, non-existence of the sponsoring company, false documentation, or a hire that never materialises can result in fines and in temporary or permanent cancellation of the registration — which removes the company’s ability to bring anyone in at all.

The same registration is what allows a company to issue formal invitation letters for foreign nationals travelling to Argentina for business meetings, congresses or technical activities.

What the application requires

Beyond the sponsor’s registration, an application for temporary residence as a contracted worker typically requires a pre-contract of employment, the employer’s tax registration, and evidence of the employee’s registration with the tax authority. Documentation from abroad — qualifications, criminal record certificates, civil status documents — must be legalised or apostilled and translated.

Applications are filed through the migration authority’s online platform. Once filed, the authority issues a provisional residence certificate, valid for 90 days and renewable, which authorises the holder to reside, work, study, access healthcare and leave and re-enter the country while the application is decided. It does not guarantee a favourable outcome.

Temporary residence runs for a defined period and is renewable. Timelines vary considerably by category and should be planned in months, not weeks.

Two routes that are faster

Mercosur nationals — including citizens of the bloc’s member and associated states — access a simplified temporary residence route based on nationality rather than on a job offer. Where a role can be filled from the region, this is materially faster and avoids the sponsorship track entirely.

Business visits. Meetings, negotiations and technical activities are handled through the transitory category rather than through work authorisation. The boundary matters: transitory admission does not authorise employment, and using business entry to have someone actually work in Argentina is a common and avoidable error.

What Decree 366/2025 tightened ⚠️

The 2025 reform moved in a restrictive direction, and three changes affect corporate assignees directly.

Absence cancels residence. Temporary residents may not be absent from Argentina for six months or more, and permanent residents for one year or more, without risking cancellation. For a regional executive based in Buenos Aires but travelling constantly, or for an assignee who returns home for an extended period, this is a real trap. Limited exceptions exist.

Healthcare requires insurance. Outside emergencies, foreign nationals who are not permanent residents must present health insurance or pay in advance at national public health facilities. Assignment packages that assumed access to the public system need revisiting.

Entry and stay impediments were broadened, with stricter treatment of criminal records both at entry and as grounds for cancelling residence already granted.

The decree also created a government agency for citizenship-by-investment programmes, which is worth monitoring but is not an operational route today.

Other risks ⚠️

Starting work before authorisation. Employing someone without the right migration status exposes the company to sanctions and undermines the employment registration itself.

Assuming remote employment avoids the question. Someone working in Argentina is working in Argentina, whoever pays them and from where.

Planning to the visa and forgetting the employment. A foreign worker in Argentina is an Argentine employee, with the collective agreement, severance and social security consequences that follow.

Letting the sponsor registration lapse, then discovering it when an urgent hire is already agreed.

What to do 📌

• Register as a sponsor before you need to, and keep the registration and the underlying corporate data current.
• Test the Mercosur route first for any role that can be filled regionally.
• Start document legalisation early. Apostilles and translations, not the application itself, are what usually cause delay.
• Track absences for every assignee against the cancellation thresholds.
• Include health insurance in every assignment package.
• Classify business travel honestly and keep it out of the working category.
• Run the employment and immigration workstreams together — the pre-contract, the payroll registration and the residence application are one process.

The strategic view

Argentina remains open to foreign professionals, and the regional route makes staffing from within Mercosur genuinely straightforward. But the system places the burden on the employer at the outset, and the 2025 reform tightened the conditions attaching to residence once granted.

The companies that manage this well treat sponsor registration as infrastructure — set up before the first assignment, maintained regardless of current need — rather than as a step in a hiring process. The ones that treat it as a step discover the inspection, the security requirement and the timeline at the moment they have already promised someone a start date.
