Dear Sir/Madam:
I have a question about the US green card holder enter USA from Canada. I heard that if you enter USA from Canada, the US boundary officer only slid your green card, not see your passport, in this case they do not have record how long have you leave the USA. Is that true? I also heard that this policy will change soon, they will see your passport and stamp the data you enter. Is any body know when they will change this policy?
Thanks!
