No, we did not end up going that route after all.
There was no option at the interview to do our oath on the spot. I mentioned to the IO that we had travel plans coming up in the immediate future and asked if it would be possible for him to note that in our file in hopes that they would possibly schedule our Oath Ceremony for a date after we return from our trip and he simply said "just go on the trip and in the event your Oath is scheduled while you are gone then you can just call us or email us to reschedule". I thought, okay that's not a bad idea......one week later we got a letter in the mail...lo and behold the Oath Ceremony Date was set for right in the middle of our trip. Rescheduling is not as simple as just calling or emailing them like the IO had advised come to find out. After reading the letter closely, it explicitly says that you must physically mail in the included form along with a letter stating the reason why you intend to miss the Oath Ceremony. It also gives reasons allowed, one being if your afflicted with COVID or if you have some sort of an family emergency, etc. They don't really clarify exactly what "emergency" entails so it could be construed in a number of ways....one being that standard vacations don't count. So in summary, the risk of them giving us grief on rescheduling along with the uncertainty that we could even get an emergency passport application appointment was more than enough for us to rethink our plans so we just decided to reschedule our trip, at a loss of course, in order to just get this whole process over with once and for all.
