I got a call a few days ago saying the Iceland partners had guaranteed me a host family in Iceland and I was accepted!
I got the e-mail just yesterday, and I got another call today explaining some more things from the application advisor. Also, something you guys might like to hear: at first, I was the only person in the US that was accepted by AFS-Iceland. Holy crap.
I heard later that AFS-Iceland had expanded and said they could accommodate two students from the US, so the other person is somewhere out there. Somewhere.
Also, holy crap.
