Question. You used to get the green form stapled to your passport, but that seems not to happen now. How does the US immigration system know I have left and am not going to be flagged up as overstaying?
Do I have to do anything?
Or will my departure from Montreal be flagged up as leaving the US?
The system should know you have left - one assumes the airlines are passing this to the US Government.
