Portugal is among the European countries that fully recognize and allow dual citizenship, meaning individuals can hold Portuguese nationality without giving up their original citizenship. This flexibility makes Portugal an attractive destination for those seeking to expand their global opportunities through investment, ancestry, or long-term residency.
Whether obtained through birth, descent, naturalization, or the Portugal Golden Visa program, Portuguese dual citizenship offers significant advantages in terms of mobility, security, and economic prospects.

What is Dual Citizenship?
Dual citizenship, also known as multiple citizenship, means that a person is a citizen of two or more countries simultaneously. This means they have the rights and responsibilities of a citizen in each country.
Here's a breakdown of what that entails:
Rights:
Holding passports from multiple countries.
The right to live, work, and study in each country.
Access to social services, healthcare, and education in each country.
The right to vote in elections in each country.
Consular protection from each country's embassies and consulates.
Responsibilities:
Obeying the laws of each country.
Potentially paying taxes in each country (depending on tax laws and residency).
Potentially being subject to military service in each country (depending on the laws of those countries).
It's important to note that:
The rules governing dual citizenship vary significantly between countries. Some countries allow it without restriction, while others have strict limitations or prohibitions.
Even when dual citizenship is permitted, there can be complexities related to taxation, military service, and consular protection.
Does Portugal Allow Dual Citizenship?
Yes, Portugal permits dual citizenship with no restrictions on maintaining multiple nationalities. Unlike some countries that require applicants to renounce their previous citizenship, Portugal allows individuals to retain their original nationality while enjoying the full rights of Portuguese citizens.
This policy makes Portugal an excellent choice for investors, expats, and individuals with ancestral ties to the country.
