@scylla @canuck78 @Bryanna , can you please provide ur opinion about U.S..Visa issues with any of the "Five Eyes" countries can impact the others. In case you are not aware, there is immigration information sharing between Canada, USA, UK, Australia and New Zealand.
Thanks @zardoz. Yeah, I understand information is shared between U.S. and Canada (and other countries). My question is about the practical impact. I understand it's always on the discretion on the border official. I wanted to know if there is any data/experience of people who faced any issues like this.
If they have always followed all the rules, had been to U.S. multiple times, with all trips being short, have no ties to U.S, would a U.S. CBP officer be very concerned about past Canadian border issue of this kind.
