I'm a Canadian, my wife is Japanese. We are currently in Canada waiting for her Permanent Residency. Our two kids, who are 5 and 8, were born in Japan and hold Japanese passports, are with us in Canada and enrolled in school. We listed them on my wife's Permanent Residency application. Right now, I'm about to apply for an extension on my wife's vistor's visa as we wait for her PR to come through. Do I need to apply for an extension for them as well or are they considered Canadian?
