US Bill could End Dual Citizenship for Americans in Europe

American citizens living in Europe could see their ability to hold a European passport cut off if a new bill were to become law in the United States.

Republican Senator Bernie Moreno of Ohio introduced a bill to the Senate on Tuesday that would eliminate the possibility of having dual citizenship for Americans.

Moreno’s “Exclusive Citizenship Act of 2025” would establish that US citizens “shall owe sole and exclusive allegiance to the united States,” according to a text of the bill.

Put simply,the bill would prohibit dual or multiple citizenship for US citizens,whether they reside in the US or abroad,including in Europe.

This would prevent Americans in countries like France, Denmark, Germany, Italy, Spain or Sweden from gaining a secondary citizenship.

Also,the proposed law would require any Americans who have already gained dual citizenship in those countries to renounce their second citizenship or else renounce their citizenship to the US.

What does this mean for Americans in Europe?

The text of the proposed law is clear: “an individual may not be a citizen or national of the United States while simultaneously possessing any foreign citizenship.”

For Americans living in foreign countries that allow dual citizenship, this means that they cannot go through the naturalisation process in the country in which they now live.

The bill states that a US citizen who voluntarily gains foreign citizenship after the law is enacted “shall be deemed to have relinquished United States citizenship.”

As for the Americans in Europe who are already dual-passport holders, they would need to make a decision as to whether they renounce their US citizenship or their European one.

Renouncing american citizenship is a costly and time-consuming process.

It’s certainly worth noting that this would also apply to the children with a US citizen parent who have so far been able to have a US passport.
