i have been scheduled an oath ceremony on October 20th 8:15am in Philadelphia, my N-400 is with a name change, so i am just wondering how long will the oath ceremony be so that i can make an estimation on time and purchase a bus ticket. thank you.

Oaths can take anywhere from 30 min to 2 hrs, depending on DO and size of ceremony.
