THIS IS AN IMPORTANT MESSAGE for everyone WAITING FOR OATH and intending to travel during this period.
I have received my oath letter today.
It clearly says that if you cannot attend the oath, you have to submit a NEW application for citizenship. Which means that your current file will be cancelled.
OR, you must convince the citizenship judge within 60 days with a valid reason why you could not attend the hearing.
In my opinion both these options are a huge waste of time and not worth it...if you're making travel plans, please keep this in mind. It's not very easy to reschedule an oath.
In the worst case scenario, inform CIC BEFORE you travel so they will put your file on hold for that duration. It's a better option than any of the ones above.
