10 easiest countries to get dual citizenship, second passport in 2026
Getting a second passport in 2026 usually comes down to three main routes offered by different countries: citizenship by investment, fast-track naturalization, or citizenship by descent.
The “easiest” countries are typically those with low residency requirements, fast processing times, or relatively straightforward investment programs.
Here are 10 of the easiest countries to get dual citizenship or a second passport in 2026.
- Vanuatu
Often considered the fastest citizenship-by-investment option. Processing can take as little as 45–60 days, with no residency requirement. Minimum contribution is around $130,000. - São Tomé and Príncipe
A newer and cheaper citizenship-by-investment program launched in 2025. It reportedly starts around $90,000 and can be completed remotely within a few months. - Dominica
One of the most established Caribbean citizenship programs. Known for relatively low investment thresholds and visa-free travel benefits. Processing usually takes 3–6 months. - Antigua and Barbuda
Popular for families because dependents can easily be included. Requires limited physical presence and offers broad visa-free access. - Grenada
Attractive because citizens may qualify for the U.S. E-2 investor visa route. Citizenship processing is relatively quick compared to many countries. - Turkey
Citizenship is available through real estate investment, usually around $400,000. Turkey allows dual citizenship and processing is comparatively fast. - Argentina
One of the easiest naturalization routes globally. Legal residency for about two years may qualify applicants for citizenship, and dual nationality is generally allowed. - Brazil
Brazil permits dual citizenship and has relatively flexible residency-to-citizenship pathways, especially for investors or people with family ties. - Ireland
One of the easiest European passports to obtain if you have Irish ancestry. Citizenship by descent is widely used and grants access to the EU. - Italy
Still popular for citizenship by ancestry, although rules tightened in recent years. If eligible through family lineage, it remains one of the strongest second passports available.
