For the Oath, the moment in which you officially become an American citizen, you have to bring document N-445 with the Oath appointment. Make sure you fill the back, signature included. You will also need to bring your Green Card.
The Oath will be in the same place where the interview was. Remember the metal control! it is possible they will be more restrictive for the Oath than for the interview (I was not allowed to bring in my glass water bottle). Before passing the metal control you will need to show a type of ID (you and the people with you), and the document N-445. The next person will ask you for your Green Card given that without it you won't be allowed to do the Oath.
Once inside, your accompanying crew will pass to the waiting room and you will stand in a couple of lines to have someone check you have all that is needed, and later to hand over your Green Card and the N-445. Finally, you take your seat, where an envelope with a bunch of stuff will be waiting for you. Once all the applicants have handed over their documents and are seating down, the accompanying crew will enter.
All of this, I imagine, may change from place to place, so be aware of it. For my ceremony, the appointment time was 12:30, but I was recommended to arrive at 12. They also informed me we would be done between 2 and 2:30, and so it happened.
As part of the ceremony there will be some videos, the Call of Countries, the National Anthem (The Star Spangled Banner), the Pledge of Allegiance, the Oath of Allegiance, and the handing of Certificates.
In the envelope you will find:
- A booklet with the Declaration of Independence and the USA Constitution
- A booklet entitled the citizen's almanac, with fundamental documents, symbols, and anthems of the USA
- Your rights and responsibilities as a citizen
- Tips for new citizens
- 14 facts about federal elections
- An application for the vote registry
- An application for the American passport + process information
- A folder for the citizenship certificate
- A little USA flag
- A message from the president
If you have completed all this process I hope the information you found here was helpful and...
Congratulations colleague citizen!
It has been a decently long process and I hope you can feel proud of your accomplishment, and that you may represent well this country you are now part of.
