@J Rogers,
I have a female friend who is Canadian and she is seeing a man who lives in the United States. They seem to think that she can come into the U.S., and that she can periodically leave and that within a 12 month span she can be here longer than a total of 6 months. She says as long as the time is broken up, she can be here more than 6 months out of the year.
That is not correct, is it?
Also, do you know if the U.S. and Canada share data on who is coming and leaving? That would be the only way that the U.S. would know exactly how long someone had been in the Country. Otherwise, they only see people entering.
