How to Get Dual Citizenship and Which Countries Allow It (2025 Guide)

Dual citizenship (also known as dual nationality) means a person is legally recognized as a citizen of two countries at the same time. This status grants you the rights and responsibilities of citizenship in both countries — including passports, healthcare, and property ownership.

Benefits of Dual Citizenship

• Travel freedom: Use either passport depending on visa benefits
• Property rights: Own land or real estate in both countries
• Education & healthcare: Access public services in both countries
• Business opportunities: Easier cross-border trade or investment
• Cultural identity: Preserve heritage while living abroad

How to Get Dual Citizenship

There are 5 main ways people acquire dual nationality:

1. By Birth
   If you’re born in a country that grants citizenship by birthplace (jus soli) — like the U.S. — and your parents are from another country, you can often claim both.
2. By Descent (Ancestry)
   Many countries offer citizenship if your parents or grandparents were citizens. Italy, Ireland, and Poland are popular for ancestry claims.
3. By Naturalization
   You can apply for citizenship after living in a country for several years (e.g., 5 years in Canada or 3 years in the UK if married to a British citizen).
4. By Marriage
   Marrying a citizen of another country may shorten the naturalization process (e.g., France, Spain).
5. By Investment
   Countries like St. Kitts & Nevis, Dominica, and Malta offer “citizenship-by-investment” programs in exchange for real estate or donations.
