In I-485, for some silly reason that we did not write down our US living address history in details. For example, from 1999 to 2001, I lived in the same city of US working for the same company, but I lived at one place of the city for one year, lived in the second place for 6 months, and third place for another 6 months. In I-485, I only put the first address for the whole two years. Is it will be a problem. And, I still hold a Canada drive license, it will affect my background check? by the way we did not show our Canada living address either (less than one year).Any suggestion will be highly appreciated!!
