Lisa, I'm in the same situation. When I went to the Consulate, there was a sign at the security desk with an email address to request an appointment to submit my PU letter, passport and visa application. That was a few days ago and no reply yet, though the security guard said everyone she's seen write down the email, she's seen them again, which sounded promising. Good luck!
Use the email I provided to communicate this...
