Just wanted to report that a friend of ours hit an unexpected problem at her interview on the 29th. She did not have a notarized letter from the father of her 17 1/2 year old daughter granting his permission for her to leave. As far as I have ever heard, it has never been required or requested, although we had such a letter handy just in case.
She got the letter, returned the next day, and was told that she will have to have it redone--it was accidentally dated 2003, instead of 2004 (why didn't the notary catch that?). Assuming this takes place, everything else was fine, no other new wrinkles to report.
