I know a couple (Indian), whereas, the wife came on visit visa and applied work permit to bypass the spousal sponsorship timeline. Basically what happened was, immigration Canada asked the wife to return after two years (of living together in Canada) and apply via spousal sponsorship again (to obtain citizenship). India being 10 months for spousal sponsorship Canadian immigration delayed their case to about 28 months. (Obviously it was deliberate). I was shocked to hear it and he tried everything to keep her here. (But CIC sent her back and made her come via spousal way).
