Urgent - oath ceremony in atlanta at 8pm?!

[Danielgate]

Hello, Just received my oath ceremony notification for 3/29/11 at 8pm. Could this be a mistake? I don't think the office is open after 330pm to the public. Can someone shed some light on this? I'm unable to get an Infopass Apt before then.
Thank you
DG

Call USCIS customer service to clarify. Might be a typo.
