Caruana to Play in 2013 US Champs?

The 20 year-old Italian-American Grandmaster Fabiano Caruana has expressed an interest in playing in the 2013 US Chess Championships.

Caruana was born in Miami but relocated to Europe with his family when he was 12. He is now rated #5 in the world, and is the world's strongest junior by a wide margin.

However, it is unclear whether Caruana would be eligible to play. Despite having dual citizenship of the US and Italy, the US Championship is regarded as a Zonal event by FIDE, and since Caruana plays for Italy he may not be eligible to take part.

If Caruana took part in the 2013 US Championships it would certainly add an extra dimension to the event, but should he be allowed to play? Have your say in the comments...
