This blog is written by a man in Canada who was shocked when he was denied entry into the USA because of a criminal conviction from 15 years previous.  I found the process of applying for a US Entry Waiver extremely difficult, and hope to help other Canadians navigate the process much more efficiently than I did.

Even if you have paid Canada pardon services for a record suspension, US immigration officials do not seal their record of your crime and will still deny you entry at the border.  A US government waiver is the only way to get permission to enter the United States again.
