It doesn't matter. If your sister is now common-law then you need to inform the visa office, and your sister and her kids will be removed from the application. They can NOT immigrate to Canada with you, else it could put all your PRs in jeopardy as you would be committing immigration fraud/misrepresentation.ajfaigao89 said:the second child of my sister born 2012 was just forcedly included by my mom in her application when the cic sent my mom the kit in february 2014 containing the docs we need to submit including the medical request thinking that everything would be ok, the first child born 2009 was already included in the application since 2011.I will let my mother know about this definitely today..
