Would you believe the British Embassy is closed for Columbus Day? Argh!
Anyway, the Embassy in Atlanta doesn't process visas - looks like the closest are NY and DC, so we're using an expediting service in NY. I just don't see her doing DC or NY alone - she's a little (ok, maybe a lot) on the sheltered side - grew up in a small town in NC, goes to a small college in an even smaller town. And since we can't get in touch with the NY and DC embassies today, there's no point in even considering sending her off to try it herself.... Plus, the embassy site itself recommends using an expediting service - they have a list of them. Regular humans have to make appointments - the services just walk in and magic happens.
She'll feel better when I tell her they don't even let their own citizens in.

Looks like all she'll be missing is the exchange student orientation week. Assuming all goes well from here!
