I am officially a US citizen.
Well, at least on paper. I am waiting to find out when I take the oath.
And, if it wasn't clear already, the US government is inefficiently run. Or, at least, they hire rather incompetent people to fill fairly important roles. The woman (girl? she seemed younger than I was) who conducted my interview was not well-versed in immigration laws. It might help to be familiar with them if you wield that kind of power.
Anyway, welcome to America! ^_^
