I just recd my canandian PR. i live in US under H1b visa and I want to move to Cananda with my wife. I will have to travel each week to work in the US. Can I do it? If so, how will I be able to maintain my PR status in Cananda?
H1B visa has no impact if you receive cdn PR status. As long as you live in US, you can continue working on your existing H1B status.
If you want to move to Canada though and commute to work in the US, that's possible. But the days you spend in the US will not be counted towards your cdn residency (and citizenship time in the future). You have to live in Canada for 2 years (730 days) in every 5 yr period to keep your cdn PR status alive.
