Argentina Residency via Unión Convivencial (Conjugal Partnership) for US Citizens

This guide provides an exhaustive, legally accurate breakdown of how United States citizens can obtain legal residency in Argentina based on a Unión Convivencial (Conjugal Partnership / Civil Union) with an Argentine citizen or permanent resident. Under Argentine immigration law (Ley 25.871), family reunification is a fundamental right, and a legally recognized civil union carries the same immigration weight as marriage.

1. Detailed Eligibility Requirements

To qualify for residency under this pathway, the US citizen applicant must meet the following criteria:

• Partner Status: The sponsoring partner must be an Argentine native, a naturalized Argentine citizen, or hold Argentine Permanent Residency.
• Two-Year Cohabitation Rule: Under the Argentine Civil and Commercial Code (Art. 509), a Unión Convivencial requires a minimum of two years of continuous cohabitation to be legally recognized.
• Proof of Union: You must prove this union either by registering it at the local Argentine Civil Registry (Registro Civil), obtaining a Public Deed (Escritura Pública) from an Argentine Escribano (Notary Public) with witnesses, or presenting an apostilled civil union certificate from the United States.
• Clean Criminal Record: The applicant must have no serious criminal convictions in the US (federal level) or Argentina.
• Legal Entry: The US citizen must have entered Argentina legally and possess a valid entry stamp.

2. Pre-Application Lead Times

Before traveling to Argentina or initiating the application, US citizens must gather specific documents that have long lead times:

• FBI Background Check (4-8 weeks): You must obtain an Identity History Summary from the FBI. This document must then be sent to the US Department of State in Washington D.C. for a federal Apostille. Do not open the digital PDF or alter it; Argentina requires the official apostilled version. Note: The background check is only valid for 90 days from the date of issuance.
• US Birth Certificate (2-4 weeks): Must be issued by your state of birth and apostilled by the Secretary of State of that specific state.
• Proof of Cohabitation Gathering (Ongoing): If you plan to prove your 2-year cohabitation in Argentina via a Public Deed, you must gather joint leases, joint bank account statements, or utility bills in both names from the US to present to the Argentine notary or judge.

3. Step-by-Step Application Process

Step 1: Enter Argentina US citizens enter Argentina visa-free for up to 90 days as tourists. Ensure you get an entry stamp or digital entry record.

Step 2: Formalize the Unión Convivencial If not already registered abroad, you and your partner must formalize the union in Argentina. You can do this at the Registro Civil or via an Escribano Público (Notary). You will need two witnesses who are not family members to testify to your two-year cohabitation, alongside documentary evidence (joint leases, etc.).

Step 3: Translate US Documents All US documents (FBI check, Birth Certificate) must be translated into Spanish by an Argentine Certified Public Translator (Traductor Público) and legalized by the Translators' College (Colegio de Traductores).

Step 4: Apply via RaDEX Initiate the residency application online through the Radicación a Distancia de Extranjeros (RaDEX) portal. Upload all translated and apostilled documents, your partner's DNI, and the proof of the Unión Convivencial.

Step 5: Pay Fees and Receive Precaria Pay the Migraciones fees through the portal. Once the system processes your initial submission, you will be issued a Residencia Precaria. This is a temporary certificate that grants you the right to live, work, and travel in and out of Argentina while your application is processed.

Step 6: In-Person Appointment & DNI Migraciones will summon you for an in-person appointment to present the original physical documents and take your biometric data (photo and fingerprints). Your Argentine ID card (DNI - Documento Nacional de Identidad) will be mailed to your home address within 4 to 8 weeks.

4. Post-Arrival Mandates

• Certificado de Domicilio: Before applying for the union or residency, you must obtain a certificate of domicile from the local police station (Comisaría) or Civil Registry to prove where you live in Argentina.
• Obtain a CUIL: Once you have your Precaria or DNI, you must visit ANSES (the social security agency) to get your CUIL (Código Único de Identificación Laboral), which is required for formal employment.
• AFIP Registration: If you plan to work as an independent contractor or freelancer, you must register with AFIP (the tax authority) to get a CUIT and enroll in the Monotributo (simplified tax regime) or General Regime.

5. Required Documentation

• Valid US Passport: Copies of all pages, including the entry stamp.
• FBI Criminal Record: Apostilled by the US Dept. of State.
• Argentine Criminal Record: (Certificado de Antecedentes Penales) - Usually requested automatically within the RaDEX system, but can be obtained via the RNR (Registro Nacional de Reincidencia).
• US Birth Certificate: Apostilled by the issuing state.
• Partner's DNI: Copy of the Argentine partner's Documento Nacional de Identidad.
• Acta de Unión Convivencial: The official public deed or Civil Registry certificate proving the conjugal partnership.
• Certificado de Domicilio: Proof of address in Argentina.
• Official Translations: For all English documents, legalized by the Colegio de Traductores.

6. Legal Nuances, Compliance Rules, and Tax Implications

• Permanent vs. Temporary: If your partner is an Argentine citizen, you are immediately eligible for Permanent Residency. If your partner is a Permanent Resident, you will also receive Permanent Residency.
• Worldwide Taxation: Argentina taxes its tax residents on their worldwide income. You become a tax resident by living in Argentina for more than 119 days in a 12-month period (under specific AFIP interpretations) or generally 183 days, or if your center of vital interests is in Argentina. There is no wealth tax exemption for family visas. US citizens must continue to file US taxes, though the Foreign Earned Income Exclusion (FEIE) and Foreign Tax Credits (FTC) can prevent double taxation.
• Dissolution of Union: If the Unión Convivencial is legally dissolved shortly after obtaining residency, Migraciones has the authority to revoke the residency if they determine the union was fraudulent (a union of convenience).

7. Renewal Conditions & Path to Citizenship

• Renewal: If granted Permanent Residency, it does not expire, but the physical DNI card must be renewed every 15 years.
• Path to Citizenship: Argentina has one of the fastest paths to citizenship in the world. Standard residents can apply for citizenship after 2 years of continuous documented residency. Note: Unlike marriage to an Argentine citizen (which waives the 2-year waiting period for citizenship), a Unión Convivencial does not waive the 2-year wait. You must wait the standard 2 years of residency before filing for naturalization in a federal court.

8. Common Pitfalls and Edge Cases

• Insufficient Proof of Cohabitation: The most common reason for rejection at the Civil Registry or Notary stage is a lack of hard evidence proving 2 years of cohabitation. Start putting both names on leases and bills well before moving.
• Expired FBI Checks: The FBI check is only valid for 90 days. Because the US federal apostille process can take up to 8 weeks, applicants often arrive in Argentina with a document that is about to expire. Time this perfectly.
• State vs. Federal Apostilles: A common mistake is getting a State-level apostille on an FBI background check. FBI checks are federal documents and MUST be apostilled by the US Department of State in Washington D.C.
• Tourist Visa Expiration: If your 90-day tourist stay expires before you file in RaDEX, you will have to pay a fine (Habilitación de Salida / Multa) to regularize your status, though being irregular does not disqualify you from applying for family reunification.

Pre-Application Lead Times

• FBI Background Check & Apostille: Obtaining the FBI background check takes 1-2 weeks via an approved channeler. However, the mandatory federal Apostille from the US Department of State can take an additional 4-8 weeks.
• Proof of Cohabitation: Gathering robust evidence of at least two years of continuous cohabitation (joint leases, utility bills, shared bank accounts) should be done prior to arrival.
• Document Translation: All foreign documents must be translated by an Argentine Sworn Translator (Traductor Público) and legalized by the Translators' Association, which adds 1-2 weeks once in Argentina.

Post-Arrival Mandates

• Registering the Union: Upon entering Argentina as a tourist, you must formally register the Unión Convivencial at the local Civil Registry (Registro Civil) or via a Public Deed (Escritura Pública) with an Argentine Notary (Escribano).
• Local Police Check & Domicile: Obtain an Argentine criminal record certificate from the Registro Nacional de Reincidencia (takes 1-5 days) and a Certificate of Domicile from the local police station.
• RaDEX Application: Submit all documents through the online RaDEX system. You will receive a 'Precaria' (provisional residency and work permit) while the application is processed.
• DNI & CUIL: Once approved, your physical ID card (DNI) will be mailed to your registered address within 1-3 months. With the DNI, you can register with ANSES to obtain your CUIL (labor/tax identification number).

Renewal Conditions & Path to Citizenship

• Permanent Residency: Partners of Argentine citizens or existing Permanent Residents are generally granted Permanent Residency directly, bypassing the temporary residency phase.
• Path to Citizenship: Argentina offers one of the fastest paths to citizenship in the world. While standard residents must wait two years, spouses and registered partners of Argentine citizens are exempt from this waiting period and can apply for citizenship immediately before a federal judge.
• Absence Rules: To maintain Permanent Residency, you must not remain outside of Argentina for more than two continuous years. Citizenship, once granted, is irrevocable.
