(Assuming that I travel by car)
1- How does the U.S. keep track of the number of days that I have been in the country since the canadian border crossing that I drove through in June 2007 did not even bother to scan my passport?
2-Does anyone has the latest update re. info sharing between the US and Cdn border agencies? Ex. when I cross the US border and the agent scans my passport, is that info transmitted to the Cdn border agent so that they know exactly when I enterred the US?
3-Has anyone experienced a cdn border crossing that did not scan the passport since July 1st 2009?
