It sounds like, essentially what you’re saying, I think. That if your mother lied or omitted information that would have led to a denial of her citizenship approval, and this is later discovered she will have her citizenship revoked, and you would also lose citizenship. Essentially because it would be considered that she committed fraud to obtain citizenship.

However,it also sounds like if her citizenship is revoked for other reasons not involving fraudulent statements and covering up a past that would have barred her from citizenship, you will keep your citizenship providing you are in the US when hers is revoked.

That’s my very rough reading of it, and yeah, it’s a bunch of fucking legalese. It’s honestly frustrating that laws like this don’t have a “simple english wikipedia” equivalent to explain it to non-lawyers.
