But anyway, the point is that, as the rules are written, someone who has spent a grand total of 1 day in the USA in their whole life could be denied access to the USA because they have "overstayed".
You get crazy results like that when you start counting stays in other countries. With any transit via the USA you could be refused entry on the way home on a return leg.
came across this thread. I know it’s not current talk but just to add a few things…
this has been around for years.
most Canadian airports have pre clearance to the USA.
US and Canada have joint operations in many ways. Military operations in security are shared jointly under joint military command.
government agencies work together as joint ventures like in weather , coastal research, ecosystems, water management in cross border ecosystems.
if it was up to me there would be no border security like it is now but have a broader system of coordinated immigration/ visitation. Those who can come to Canada and not USA would get marked. The border crossing is just checking for that along with random vehicle searches.
