Andee: Our appt. was for 10:15, and there was a small queue outside the building. We were allowed to enter about 15 min. prior to appt. and pass through security and go up to the 10th floor (pretty sure it was 10th...there was poor signing on the elevator we were on, so we were a bit confused). Once there, we got in line at the bank teller-like area until we were called to a window. We introduced ourselves, said we were here for a fiancee visa, handed over my online application. She then started asking us for documentation, and I began taking it out of my plastic-sleeved binder; then she just asked for me to hand the binder under the glass. She came back a few minutes later, having made photocopies of my documents, and said my visa would be ready in an hour and we could either leave the building and come back or wait there.
It was MUCH easier than I thought it would be, but I think that's because our case was so cut and dry and we were over-prepared (and compulsively organized).
Since she left when she was looking at our stuff, I'm not entirely sure what she did/did not look at, but I do know that she didn't remove to copy:
-my e-ticket
-the wedding invite
She also didn't ask to see what we had in our "extras" folder:
-my birth certificate, SS card
-my old passports
-my old BUNAC card
-ANY of our "proof" of relationship stuff
We did write a letter of intent (by me) and letter of support (by him) for formality's sake. It was a few lines stating our intentions. Piece of cake.
She also seemed to keep the originals of most of the letters, but gave back anything that we might need for the future (bank statements, receipt of church booking, etc.).
Stoatula, we applied in person for the probably silly reason that we didn't like the idea of sending our passports in the mail, and because we knew he would be here and we would probably want to visit NYC anyway. (The bus ride from my hometown isn't too far.)
Hope this helps!
ps. Andee, I live in PA, too.
