no worries for those who were posting with concerns. It's long and boring, but easy if you compile everything on the list from the embassy--just make sure to check around and see that you've read everything. For instance, with DD1, DH didn't come with us, and I nearly missed the page that said you needed a signature if your husband isn't with you saying it's okay to get a passport. Happily we have a friend who's a solicitor, so he came over and certified it (worked for the notary bit) and we were fine.
We just did DD2s and no documents are kept--everything is returned to you at the window. It took us over two weeks, but we had our interview right before Christmas. The consular report and passport came separately and we just got the SS card, which took longer.
