@TomD8 But they would be non resident if living and working in Canada (their original country), yes?
As far as I know, once you get a green card, you are considered a US resident and are subject to US tax laws all all time on all your world-wide income. That's one of the costs you pay for the benefits of US residency.
If you think you are somehow exempt once you move back home, I would have to see that in writing. (If you surrender the green card, you are no longer a considered a resident.)
