Naturalidade vs. Nacionalidade: Stop Confusing Them on Portuguese Forms

Have you ever encountered the Portuguese terms naturalidade and nacionalidade in official documents and been left confused about what each one means? The mix-up is common: both appear on certificates, ID cards, passports, and application forms. Even though the words are similar, they carry distinct meanings that are fundamental when navigating the process of Portuguese citizenship.

Understanding the difference between nacionalidade (Nationality) and naturalidade (Place of Birth) is essential not only for day-to-day form filling but is critical in more complex situations, such as citizenship applications, migratory processes, and official registrations in Portugal.

What is Nacionalidade? (Nationality/Citizenship)

Nacionalidade (Nationality) is the legal and political bond that links an individual to a country. It determines the state of which you are considered a citizen, along with all corresponding rights and duties. It is your nationality that defines rights such as voting, working, residing, and receiving diplomatic protection from a country.

In many cases, depending on the laws of the countries involved, multiple nationalities can be accumulated. This is often the case for Luso-Brazilians, who hold both Portuguese and Brazilian citizenship.

Types of Nationality

• By birth in the territory (jus soli): when a person is born in a specific country and automatically acquires the nationality of that location.
  
• By descent (jus sanguinis): when nationality is transmitted by parents or grandparents, even if the birth occurred outside the family’s country of origin.
  
• By naturalization: when a person acquires nationality after fulfilling legal requirements, without a link through birth or parentage. This is the case, for example, for spouses of Portuguese citizens or legal residents who have lived in the country for a determined period.

What is Naturalidade? (Place of Birth)

Naturalidade (often translated as Place of Birth) indicates the specific geographic location where a person was born, typically the city and state/province. It is purely a geographical piece of data, not a political one.

• It is listed on the birth certificate and various civil documents.
  
• It generally does not change, even if the person acquires a new nationality.
  
• It can only be altered in very specific cases, such as registration errors (through a court-ordered rectification).

👉 Pratical example

A typical scenario involves a person born in New Jersey to American parents, who holds American (U.S.) nationality (citizenship) by birth. If this person is later granted Portuguese citizenship by descent (for example, through a Portuguese grandparent), they then hold two nationalities: American and Portuguese. Their naturalidade remains New Jersey, but their nacionalidade becomes dual (American-Portuguese).

Difference Between Naturalidade vs. Nacionalidade on Documents

In practice, this difference appears on nearly all official records, especially on Portuguese application forms:

• Naturalidade: Always related to the location of birth (city/state – freguesia, concelho, cidade).
• Nacionalidade: Always related to the country of which the person is a citizen.

A common mistake that can cause delays in the Portuguese citizenship process is filling in “American” or “U.S.” in the naturalidade field (Place of Birth), or writing their city of birth, like “New York,” in the nacionalidade field (Nationality/Citizenship). These errors can generate extra requirements or significantly postpone the issuance of documents.

Can Naturalidade or Nacionalidade be Changed?

• Naturalidade: It is generally fixed. It can only be altered in special and duly proven situations (registration errors).
• Nacionalidade: It can change. It is possible to acquire Portuguese nationality through naturalization or recognition of origin, according to the law.

Guide to Filling in Place of Birth and Nationality in Portuguese Documents

Knowing the difference between naturalidade and nacionalidade is essential in administrative and legal proceedings. Correctly providing this data is indispensable in dual citizenship applications, ensuring that there are no extra demands or rejections.

Many people confuse nationality with the naturalidade, filling in the city name in the nationality field or the country in the naturalidade field, when the correct information is the country of citizenship and the city of birth, respectively.

It is worth noting that during the process of recognizing Portuguese citizenship, several official forms require this information, including:

• Forms from the Instituto dos Registos e Notariado (IRN);
• Applications for Portuguese birth certificates;
• Specific powers of attorney and declarations;
• Nationality application forms.
