Overstaying a Tourist Visa in Argentina on a UK Passport: Fines and Fixes

If your 90-day tourist stay has expired, the ordinary route out of Argentina is a habilitación de salida, an exit authorisation. For a British passport it costs 40 UMSM, or ARS 40,000 on Migraciones' fee table (checked 11 October 2026). Pay it before departure and leave voluntarily, and there is no automatic ban on returning.

If you are still within your permitted stay, the cheaper option is a single extension of up to 90 days. The prórroga de permanencia costs 20 UMSM (ARS 20,000), with the usual application window in the final 10 days of your stay. The distinction matters: an unpaid overstay can also lead to an order to regularise, and ignoring that order can end in expulsion and a re-entry ban of at least five years.

Find the date your stay ends

British passport holders enter Argentina visa-free as tourists for 90 days. Use the authorised expiry recorded by Migraciones rather than treating 90 days as three calendar months or guessing whether the entry day counts. Passports are no longer routinely stamped, but Migraciones holds the entry date in its system.

If you have made several trips and need the dates, Migraciones issues a certificado de movimientos migratorios, a record of entries and exits. It costs 10 UMSM (ARS 10,000) for each calendar year covered. The record is especially useful before choosing between an extension and an exit authorisation.

An extension while you can still stay

Migraciones ordinarily accepts an extension request during the 10 days before the permitted stay ends. A passport valid through the new period matters, and the extension is available once, for up to another 90 days. One approved extension can add up to another 90 days; use the expiry recorded on the permission.

The application is made at the DNM (Dirección Nacional de Migraciones) headquarters, Av. Antártida Argentina 1355, Retiro, Buenos Aires, edificio 3, 08:00 to 13:00, or at a regional delegación. Bring the passport and fee; an Argentine address and an onward ticket help answer questions about the planned stay and how it is funded. Migraciones' tourist page mentions a 50% surcharge for someone who presents voluntarily within 30 days after the deadline, but the same page requires current transitory residence and says an expired stay cannot be extended. Do not read that surcharge wording as permission to overstay: ask Migraciones before the actual expiry, or arrange exit authorisation if it has passed.

What it costs to leave after an overstay

Fees are set in UMSM (Unidad de Medida de Servicios Migratorios). Under Decreto 584/2024, 1 UMSM is ARS 1,000; British nationals pay the non-MERCOSUR rate, twice the MERCOSUR rate. Convert the peso charges using the actual provider rate and fees when you pay.

The exit authorisation covers one departure with a 10-day validity period. The tourist page counts from the day after issue, while the exit page refers to payment; follow the expiry on the issued document and ask Migraciones before relying on a borderline departure date. If that period passes before you leave, another authorisation costs the same amount. At Ezeiza, allow at least an hour before check-in closes to start the process rather than arriving at the counter at the last minute.

Migraciones opens the case and issues a Boleta BURe for payment at Banco de la Nación Argentina, Provincia Pagos or the payment desks in the headquarters buildings. Return to the counter for the Formulario de Habilitación de Salida, which you show with your travel documents at the border. The headquarters handles this in Edificio 6, counters M, Monday to Friday 08:00 to 16:00; regional offices also handle it. Ezeiza operates 24 hours and Aeroparque 07:00 to 22:00. Land border crossings no longer collect the fee: leaving with it unpaid creates a debt that blocks re-entry until paid, including by card from abroad on the Migraciones site.

When the overstay becomes an immigration case

An overstay paid for on voluntary departure differs from an expulsion. Under article 61 of Ley 25.871, Migraciones can order someone it finds overstaying to regularise by a deadline, through a qualifying residence application or departure. Staying on despite the order risks expulsion; article 63 attaches a re-entry ban of at least five years. Do not infer Argentine consequences from UK overstay rules: use the Argentine notice and current law for the actual case.

A tourist entry also does not permit work for an Argentine employer. Someone planning to live in Argentina rather than visit needs a residence route that fits their circumstances; remote work for UK clients belongs on the digital nomad route. This becomes more important after successive short trips abroad.

Why a border run is a fragile plan

A new tourist admission may authorise up to 90 days; no number of entries guarantees admission. From Buenos Aires, a common trip is the ferry to Colonia del Sacramento in Uruguay: Buquebus departs from Av. Antártida Argentina 821 in Puerto Madero, while Colonia Express leaves from Av. Pedro de Mendoza in La Boca. Check the operator's timetable and border procedure, and Uruguay's current entry requirements, separately from the Argentine stay.

Check the operator's actual sailing, return fare and cancellation conditions before booking; a ferry ticket does not guarantee Argentine re-entry. Other crossings include the Cristo Redentor pass into Chile from Mendoza, which can close in winter snow, and Foz do Iguaçu in Brazil from Puerto Iguazú. Repeated short departures may lead to questions about the purpose of the stay; no fixed number of trips assures admission. An officer can refuse entry to someone plainly living in Argentina as a tourist.

How a longer stay changes the calculation

Consider a British couple aged 58 and 61 who arrive at Ezeiza on 1 July 2026 to try a year in Buenos Aires. She receives about £1,500 a month from a let flat in Leeds; he draws a £1,100 monthly workplace pension. They take a furnished flat on a six-month contract and follow the authorised tourist expiry recorded by Migraciones.

In this hypothetical example, applying for extensions during the final 10 valid days at Retiro costs them 2 × 20 UMSM, or ARS 40,000 together, and extends their stay to the new recorded expiry. Their ACRO police certificates, ordered before departure, are apostilled by the FCDO and translated in Buenos Aires; they add Argentine criminal record certificates. During October they file through RaDEX, Migraciones' online system: she applies as a rentista, he as a pensionado. Each applicant compares their own monthly income, using the conversion basis Migraciones accepts for their application, with five times the minimum wage (ARS 1,956,000 a month in October 2026). The two temporary residence filings cost 2 × ARS 100,000, or ARS 200,000.

If Migraciones accepts both filings, each receives a residencia precaria, a provisional residence certificate valid for up to 90 days at a time, that keeps them legal beyond their tourist expiry while Migraciones decides; the published Migraciones procedure gives no fixed decision time. Missing the recorded expiry would have left them without a tourist extension and facing a 40 UMSM exit fee each. Check the actual insurer's single-trip duration, residence and work exclusions before a long stay; annual cover does not necessarily cover the whole planned trip.

Dual British-Argentine nationals enter and leave on Argentine documents. A person already holding a precaria or residence follows the dates on that document instead of the tourist clock. For a visitor still deciding how long to remain, the relevant choice is between an extension before the stay runs out and a qualifying residence application for life beyond it.
