What is the ruling on obtaining American citizenship, and what is the ruling on one who obtains it by dependency while young?

Whoever obtains the nationality of a disbelieving country while young, dependent on his parents, bears no sin for it. His ruling is that of the people of that land. After reaching the age of accountability, he must safeguard his religion. The ruling regarding migration from a land of disbelief to a land of Islam differs for him between obligation and recommendation, depending on the circumstances.
