I passed my interview today! The IO gave me the N-652 form, and told me to wait for the oath ceremony.
It was a pretty straightforward interview, although I was a little worried because I had two 4-month trips but everything went well. I was surprised that she didn't ask for any tax transcripts, or bank statements etc. She asked for my passport, green card and ID. All in all, it lasted about 15/20 minutes. I am closer to the end of my journey, hopefully it will be over soon.
My civics questions were:
What is freedom of religion?
When was the constitution written?
What ocean is on the east coast of the US?
How many senators are there?
When do all men register for selective service system?
Name one state that borders Canada.
I'd be happy to answer any questions that you may have.
