hey Guys,
I am now in Canada. This was the most smooth entry I have had so far coming here. At the Buffalo border the officer asked me where i lived, why i was coming into Canada, Where I was staying, and if i was going to work for my friends and then he said enjoy your trip. Oh by the way he wiped my GC but I noticed that he never Stamped my RTD. How does the US knows that I ever left the country? And for how do i prove for how long I left?
