U.S. Green Card and Canadian PR Card

[Tim2009]

I am a Canadian Citizen working in USA (since Mar 2006). My wife is Canadian Permanent Resident (since Nov 2003) and has valid PR Card. Recently we (My wife & myself) got US Green (GC) Cards.
As far as I know, the spouse of a Canadian citizen can maintain PR status, even if he/she is not living in Canada for a long time, as long as she/he is accompanying with his/her spouse. It means that the Residency Obligation does not apply on the spouse of a Canadian Citizen.

Now the questions are:

1- Can a spouse of Canadian citizen, living in USA with her husband, have US Green card and Canadian PR cards (permanent residency of both countries) together?
2- While crossing the Canadian/US border, would she have any problem or issue?
3- Would the Green Card Jeopardize her Canadian PR status?

does anyone have insight on this?

Because YOU are a Cdn citizen, as you said, she does not have to meet the residency requirements for Cdn PR.

So, neither her US GC, nor any other foreign status, will not impact her Cdn PR status.

when crossing into US, she shows her GC, and provides evidence of maintaining her residence in US.

When crossing into Canada, she shows her passport and her Cdn PR card. Even if she shows her US GC, no harm will come. She need not show any evidence of residence in canada, because of you.
