Oath Ceremony

At the oath ceremony, you will swear your allegiance to the United States and receive your naturalization certificate. Once you receive this certificate, you can apply for a U.S. passport and vote in national, state, and local elections.
If you have opted to change your name, your new name will be on your naturalization certificate and you will be able to apply for other official documents (Social Security card and driver’s license, for example) in this new name.

Depending on where you live and the oath ceremony schedule in your district, you could be scheduled as soon as the same day you pass your interview; or, you might have to wait several months before taking the oath.
It might take place in a small room or a courtroom in a federal or state building or a large stadium or convention center. Sometimes special ceremonies are scheduled in historical landmarks such as Independence Hall or the U.S.S. Constitution. No matter where the oath ceremony is held, this is a momentous occasion, so make sure to wear appropriate clothing. (This is really not the day for jeans, T-shirts, shorts, or flip flops.)
You must attend your oath ceremony appointment unless you request a new date and provide information as to why you cannot attend. You should arrive about an hour in advance of your appointment time, as you will need to check in with a U.S. Citizenship and Immigration Services (USCIS) officer. This officer will double check your eligibility and collect all your paperwork.
