Argentina

Argentine citizenship law rests on Ley 346, in force since the nineteenth century and elaborated since by decree and administrative practice. Its first article recognizes as Argentine the children of native citizens who, born in a foreign country, opt for the citizenship of origin. That single clause is the foundation of most of the Argentine work we do.

The opción is not an application for naturalization. It is the exercise of a right that already attaches to the family relationship — which is why the evidentiary work centres almost entirely on proving that relationship, document by document, back to the Argentine-born ancestor.

A typical file rests on the Argentine birth record of the ancestor, obtained from the relevant provincial civil registry, together with the uninterrupted chain of foreign birth and marriage certificates connecting each generation — apostilled and translated where required. Argentine records are held provincially, and their condition varies: a Buenos Aires record from 1910 may be pristine; a rural entry from the same year may require patient correspondence with the registry that holds it.

Once recognized, the new citizen is documented through RENAPER, the national registry of persons, which issues the DNI; the passport follows from the DNI. These final administrative steps are unglamorous but consequential, and we stay with families through them.

The most common difficulties are evidentiary rather than legal: names hispanicized or misspelled at migration, ages shifted between documents, and civil records that must be rectified before they can support a filing. Consular practice also varies more than families expect — two consulates applying the same law may ask for materials in different form, on different timelines.

Argentine practice has also seen periodic regulatory adjustment, particularly around naturalization and residency routes. The descent option has been comparatively stable, but as everywhere, current consular requirements should be confirmed before filing.
