The US recognizes dual nationality.
Yes, our State Department “recognizes “ that some US citizens have dual nationalities but it has no legal status with them. The major problem for US citizens holding citizenship in another country arises if/when they travel abroad with a non-US passport. A former co-worker of mine had dual US-Italian citizenship. He got into a minor legal scrape while visiting Italy on his Italian passport. The US consulate wouldn’t help him because he had not entered the country on a US passport. Another problem is if a dual national leaves the US on, say, an Italian passport and tries to re-enter on a US passport. That does not make the US authorities happy, to say the least. My friend’s advice, learned by him the hard way, is always travel to and from the US with your US passport, regardless of your dual citizenship.
“The US recognizes dual nationality.”
Hey, they even elected a “President” (Obummer...twice) with dual nationality! But mainly dual nationality is something you can’t avoid sometimes. I was born in Scotland, came here as a child and receive my U.S. citizenship as a young woman (just under 18) when my parents were naturalized in 1957. It has since changed, but in 1957 British law as such you could never renounce your British citizenship (it has since changed). Therefore, legally, I am a dual national.
