Appointment cancelled - issues with N-400? Boston

[LinT]

I received a yellow letter for additional information (most likely related to minor traffic violations/driver's re-education) three weeks ago. I just got a lettter in the mail scheduling my interview for May 11th - and then the same day another notice descheduling it due to unforeseen circumstances... IRS agent tells me it is back in line for scheduling today, most likely due to an issue on their side.
Two questions: any chance it has something to do with my case being denied/reevaluated/etc (I am a bit paranoid about the yellow letter and the 3 surchargeable incidents that led to the re-education course.... maybe I should never have mentioned it to start with)
Second : I am going abroad on June 11 - any chance I will have my interview before then?? Also, what happens if the Oath ceremony falls during the time I am abroad - can I still travel and re-enter the US iwth my green card, and does it affect my application in any way?

Thanks in advance, this board has been very helpful

I have no idea whether the descheduling had to do with your circumstances, but if you have just received that letter, I wouldn't panic yet. My appointment got descheduled as well and a day after that notice, I received a new invitation letter for a date just one week after the original one.
