honestly, does she have $465 she could spare?
In her situation, I would just apply and see what happens. You just never know and you shouldn't listen to people who THINK they know anything. I don't think she has anything to lose (other than the money lol) because they said they wont deport anyone who applies and doesn't qualify, unless they have a criminal background.
I know someone who entered at age 16 and a few months, and he applied anyways. The rules regarding certain things are not completely clear yet, so you never know and will only find out if you try.
good luck!
