I am a US Green Card Holder. My wife is a US Citizen. She applied for and got approved for Canadian Green Card. By Canadian regulations all family members/dependents are automatically issued Canadian Green Cards. As US Citizens my wife and children can freely travel to Canada/US. My question is: as US Green Card holder, could my intention to abandon residency come up if I travel to Canada, even briefly? Is there a law/regulation/case precedent in this regard? As of July both US and Canada will report to each other the border entry records and entry status. Am I violating any law if I travel to Canada as US/Canadian Green Card holder?
