You've got PLENTY of time. They wont see you without an appointment unless you are travelling within 3 DAYS. Online and make an appointment. Check a couple of times a day. If you get to the 7th and cant get an appointment, go as a walk in. Make sure you have a copy of your airline reservation. We just did it for my daughter. It worked really well, and they are pretty nice about it too. Good luck!
Tony's comment is right on. Go to www.travel.state.org for official info.
