Does the US Allow Dual Citizenship With Greece?

Yes—the United States fully allows dual citizenship with Greece. Americans are permitted to hold multiple nationalities simultaneously, as long as they continue to meet their U.S. responsibilities such as taxes and passport usage for entry and exit.

What US Law Says

The U.S. government does not require renunciation when obtaining another nationality. Acquiring Greek citizenship:

• Does not affect your U.S. citizenship status,

• Does not require any special declaration,

• Is fully recognized under U.S. nationality law.

Why Dual Citizenship Is Common

Many Greek-Americans reclaim Greek nationality through ancestry. Others obtain it through residency or marriage. The U.S. supports maintaining these ties, especially when the second nationality is through family heritage.

What Americans Should Know

• You must use your U.S. passport to enter and leave the U.S.

• You can use your Greek passport for EU travel and residency.

• Tax obligations remain unchanged—Greek citizenship does not exempt you from U.S. taxation.

Why Dual Citizenship Is Beneficial

• Easy EU mobility

• Access to European healthcare and education

• Ability to live in Greece long-term

• No need to give up your American passport

Dual citizenship is fully legal and widely practiced among Greek-Americans.
