Since their official goal is set in terms of how many oaths, may be they deprioritized all the paperwork that comes after oath, it's still surprsing they wouldn't accommodate a sibling's wedding for expedited processing.
All other offices have been so accommodating with expedite requests for urgent legitimate reasons (I have been reading so many forum posts here from past 5 days and researched a lot) as long as you provide the proof. I have seen Scarborough, Niagra, Vancouver, all doing it. What's so special about Winnipeg office that they are making me miss my sister's wedding? That too when I provided all the proof and also mentioned it during oath. I am so disgusted! It's like they are saying we will work however the way we want, your urgency or life situation is none of our business.
Is there a way to file a complaint against one of the IRCC offices? I am willing to go the extra mile and spend money and time on it too for the emotional and family disaster they have caused me.
