What is Dual Citizenship?
Having dual citizenship simply means you’re a citizen of two countries at the same time. With two passports in hand, you get another, entirely different country to call home.
Most countries allow dual citizenship, but it could be that your country might require you to renounce your nationality before you can apply for another passport. Confirming your own country’s position on this matter will be vital to check.
Beyond global mobility, a second nationality is your own personal insurance against instability: political, currency, economic. Plus, you and your family already have a safe harbor waiting for you in another country.
The best countries for dual citizenship also tend to be at the top of worldwide rankings, and are typically located be in Europe – which often have stronger infrastructures, reflected in superior healthcare and education systems.

Types of Dual Citizenship
- Investment: Some countries have programs designed to attract significant capital investment in exchange for residency or citizenship. This is the only type of dual citizenship that you can obtain that is completely within your control, as it lets you choose where to invest and what the best country is for your needs.
- Birthright or by Descent: When you inherit your parents’ or grandparents’ citizenship from another country. Some European countries allow up until the third generation of immigrants to claim citizenship.
- Naturalization: When you spend a certain amount of time in another country for a certain number of years. For example, you can become a Portuguese citizen after five years and a Greek citizen after seven years.
- Marriage: Only some countries accept it as a legal means for a foreign national to get citizenship. Usually, marriages are only accepted if both spouses are living in the country and only after a set amount of time has passed.

What are the Best Countries for Dual Citizenship?
With so many countries allowing its citizens to have dual citizenship, it's only natural to ask: what are the best countries for dual citizenship?
The answer is easier than you think: any country with a residency or citizenship by investment program.
The smartest move isn’t chasing ancestry paperwork or waiting out a decade of residency in which you have to continously live in the country. It's choosing a country that has a clear, well-defined investment pathway toward Residency & Citizenship.
Portugal and Greece have the best programs if you're looking to have dual citizenship.
Portugal gives you the five-year fast lane. Invest €500,000 in a regulated fund, spend just an average of seven days a year in the country, and collect an EU passport that unlocks 170+ destinations, excellent healthcare, and resident-tuition for your kids.
Greece lets you start at only €250,000 in real estate. Rent out your property in long-term, and solid rental yields, and get to a powerful Schengen passport after 7 years.
Both programmes turn you into a permanent EU citizen; the choice is simply speed versus entry cost. Decide which advantage matches your ambitions and take control of your family’s future today.
