I am a Canadian citizen, but in 2005 I overstayed my time in the US for about a year and left on my own in June 2005. I tried entering back into the U.S. last year and was informed that I had a 10 year ban against my name which would expire in June 2015. What do I have to do to re enter after the ban expires? Do I have to show them any specific thing for my re entry?
No, there is no specific thing you have to do.
As always for foreigners entering, there is no guarantee of entry. It is at the discretion of the officer. Your past history of overstay can be a negative factor in their consideration.
