I had my ceremony on the 17th and I noticed something that you may want to consider.
My invite stated "NO VISITORS" but it does allow for translators to be present. (this is office specific and varies per office)
Several people in line decided to have a family member act as an translator when they realized they could not bring anybody. (reading the invite is not high on their list either apparently)
The officials let them in, but you could see they are getting annoyed by this practice. The form has to be filled out again, extra chairs needed to be placed etc etc, it all takes longer.
Unless you are over a certain age, you already proved you read, write and understand English during your N400 interview.
Eventually they will just not allow anybody else in, hurting those people that actually do need an translator.
Most federal buildings do not allow photos/videos/recordings to be taken so there is really nothing spectacular you "miss".
We had 3 people not bringing the invite (really people?) the majority having to cross out the city they used for signing (that one is less obvious) and a bunch that used the incorrect date of signing.
When you sign the form, the following is most certainly correct:
- Use the date of your ceremony
- Use the city where your ceremony is held, do not use your home city.
- When answering the questions, read the instructions. it is only to mark changes between your interview and the ceremony.
For the sanity of the people behind you in line, please read the instructions.
