Green Card and Canadian PR

[ranjoose]

Hi,

My husband applied for a Canadian PR in 2002 when he was in India. Meanwhile he came to the US and also applied for GC in 2005. In 2009, we both got our Canadian PR. In March 2011, we got our GCs. We have not tried to keep the Canadian PR status

we just entered Canada once for some initial procedures.

Since we got out GC, we dont have any intention to keep our Canadian PR status. Do we need to surrender our Canadian PRs? If I travel out of country,

will there be any problem at US POA?

Thanks.
