Argentine nationality law
history and regulations of Argentine citizenship
Argentine nationality law regulates the manner in which one acquires, or is eligible to acquire, Argentine nationality. Nationality, as used in international law, describes the legal methods by which a person obtains a national identity and formal membership in a nation. Citizenship refers to the relationship between a nation and a national, after membership has been attained. Argentina recognizes a dual system accepting Jus soli and Jus sanguinis for the acquisition of nationality by birth and allows foreign persons to naturalise.
Recent changes by the Decree DNU 366 / 2025 have tightened the requirement to get citizenship, but allowing investment methods.
Terminology
The distinction between the meaning of the terms citizenship and nationality is not always clear in the English language and differs by country. Generally, nationality refers to a person's legal belonging to a country and is the common term used in international treaties when referring to members of a state; citizenship refers to the set of rights and duties a person has in that nation.
It can be possible for a non-national to obtain a degree of civil and political rights commonly associated with citizenship (e.g., residence or working rights) while it is also possible for a national to be prohibited from exercising certain rights (e.g., children barred from voting). In Argentine, the term "nationality" (nacionalidad) refers to state membership while "citizenship" (ciudadanía) describes a person's participation in national society.
