The "Notice to appear" for oath is what it is - It's a notice not an invitation. You'll need to provide satisfactory explanation as to why you want it postponed and the officer will decide if the reason you provide is satisfactory. Some officers are lenient and some are not.My citizenship ceremony has been scheduled!!!!!!!!!!!!!!!!!!
Quick question: I'm supposed to travel out of the country the day after my scheduled citizenship ceremony. I haven't received the email from IRCC yet, but will I be able to reschedule my citizenship ceremony to after my trip?
Also, if you decide postpone the oath, there is no guarantee you will get the next available spot when you are back... You are pushed back at the end of the queue and it could be months before you get a new date. That being said, if your trip is unavoidable, you may have to reschedule your oath. But then you may get lucky...
