Didn’t get oath descheduled letter

[DrZoidberg 18]

After I passed my interview, I informed the interviewer that I needed to take a trip soon but might have to cancel due to the lack of a green card (or passport) after the oath ceremony. He reassured me not to worry and wrote, "Schedule oath ceremony after my trip date." The next day, I checked my online account and saw that the oath ceremony was scheduled. When I opened the PDF, I realized it was scheduled before my trip. I considered canceling my trip, but then three days later, my online account showed that the oath ceremony was descheduled.

I received the original letter in the mail regarding my oath ceremony details (where and when to attend), but I still haven’t received a second letter regarding the cancellation of my oath. Now, the oath ceremony is scheduled for tomorrow, and I'm unsure whether I should attend or not.

You absolutely should attend. Worst case you can apply for emergency passport if you naturalize and need to travel soon.

How did it go @DrZoidberg?

It was an outdoor venue. I went there and asked the USCIS representative. She checked my name and told me it's not on the list, and advised me to wait for another letter.

Did you show the letter with oath invitation?
