Why the naturalization fee is so high

TIME explains (without taking sides)

TIME has an article this week on the naturalization fee, and why it is so high.

(I'd have liked the article better if it wasn't so studiously neutral about the whole thing, and instead advocated for lowering the fee. But then I'm a rather opinionated gal.)
