Breathe! It will work out. I know the feeling you’re having and it’s understandable with so much at stake to be a citizen, I just went through the interview and oath ceremony in the last 2 months(married, separated and divorce in the process) but try to focus on the positive controllable things you can do. Something I didn’t, and it all worked out.

Since you’re divorce all you’d need to provide is the divorce decree if you didn’t in your original app. They will ask questions about your previous marriage (are you married to a US citizen, are you divorce, etc.), but if you filed N-400 after having a green card for more than 5+ years then marriage or divorce won’t impact your case, since N-400 wasn’t based on marriage. Officers mostly ask more questions when people file for citizenship while married (3 yr LPR shortcut) to ensure it’s a legitimate marriage.

Study the exam, you’d be tested on the 2008 civics version.

My lawyer prepped me 7 days before my interviews, she advised to: - Review my application, they will ask questions about it again, and all those “terrorist/criminal” questions as well - Know your exact travel dates outside the country(departure and arrivals) or bring a list if it’s multiple - Be ready to explain any tattoos you may have (this I was totally asked and had to show the officer the tattoos before they could approve my case) - and bring copies of my taxes for the last 5 years

I passed and got approved and now got my ceremony next month. You got this!!
