The baby’s citizenship and the parents’ residency after a birth in Argentina: what, where and in which order

In short

A baby born in Argentina is an Argentine citizen by birth, whatever the parents’ nationality (Ley 346, art. 1). Nothing has to be “applied for”: birth registration, the DNI and the passport confirm it.

Parents do not become citizens automatically. Each of them applies for temporary family-reunification residency for up to 3 years (since DNU 366/2025 it is no longer permanent). A precaria is issued while the case is reviewed and a foreigner DNI after approval. Parents can naturalise later, but those rules are currently contested in court.

All steps in order

1. Birth registration at the Civil Registry — within 40 days, often inside the clinic; you get the partida.
2. The baby’s DNI — free up to 6 months; started at registration.
3. Argentine passport — after the DNI; the baby leaves the country on it.
4. Apostille on the partida — Argentine Foreign Ministry, online via TAD.
5. Home-country citizenship — at the consulate, by appointment.
6. Parents’ residency — online via RaDEX: first the precaria, then temporary residency up to 3 years.
7. Foreigner DNI — after the residency is approved.

Steps 1–4 in detail — “Your baby’s documents after birth”; step 5 — “Russian citizenship for a child born in Argentina” and “Birth by nationality”; steps 6–7 — “Parents’ residence and DNI”. Every deadline from arrival to the parents’ DNI is in “Step by step”.

The baby’s citizenship: Argentina and the parents’ country

• Argentine citizenship comes from being born in the country; the exception is children of foreign diplomats.
• Home-country citizenship is processed at that country’s consulate — see Birth by nationality.
• Argentina allows dual citizenship; whether the parents’ country recognises it depends on the country (Kazakhstan and Belarus, for example, do not).
• How to spell names so both countries’ documents match — “Patronymics in foreign documents”.

Parents’ residency: what changed and how to apply

The ground is the Argentine child (Ley 25,871, art. 23 ñ as amended by DNU 366/2025); residency is temporary, up to 3 years, renewable. Each parent applies separately, online via RaDEX and only while legally in Argentina — do not let your tourist stay expire before filing. You need a passport, the baby’s partida and DNI, criminal records from countries where you lived over a year in the last three years (apostilled, with a sworn translation) and proof of address.

Fees, precaria deadlines, renewal and what happens after a long trip abroad are covered in “Parents’ residence and DNI” and “Precaria”.

Parents’ citizenship: later, under contested rules

Under DNU 366/2025 naturalisation is handled by Migraciones and requires two years of continuous legal residence with no trips abroad; the precaria does not count. Several courts in 2026 declared these rules invalid for individual applicants, and the Yang case reached the Supreme Court on 7 October 2026. Until there is a final decision, the route is chosen case by case with a lawyer — see “Argentine citizenship in 2026”.

Common mistakes

• Filing for residency after the tourist stay has expired.
• Different Latin spellings of the surname in passports and the partida.
• Not apostilling the partida before the consulate appointment.
• Assuming the birth gives parents permanent residency or citizenship right away.
• Long absences on temporary residency without Migraciones’ permission.
