Usually the IO, during the interview, states the timeframe. Typically it`d be anywhere between 1-3 months. There are a select few who had taken the oath the same day, as well as a few who took it the next day, or called within a week or two. And there are also an unlucky few who had been waiting for months (6+). But neither of it is the norm. If you don`t hear from IRCC within 6-weeks pls shoot a
webform enquiry.
