You can only get a US passport after your oath ceremony, once you're a citizen with a naturalization certificate. But if your travel is very soon after the oath (i.e., not enough time to go through the expedited process), you can apply for an emergency/urgent passport.

Some people in this thread have gone the urgent passport route, so if you scroll back some pages you'll be able to find info on it.
It's definitely still cutting it close to your travel in Nov because it's hard to predict how soon your oath ceremony will be scheduled.
