where did I say anything about her needing a visa or not? I didn't mention it at all. That's for you to figure out
Keep in mind children under 15 can't be fined for overstay and children under 18 can't be banned for overstay.
Now that's not the same as saying she doesn't need a visa/extension to stay only that there are no penalties for overstaying.
