I'm not sure I understand.well,
okay but I had applied for arts program in usa, visited it for 3 months and came back and after working for an year applied for a computer science stream in canada.
do u think this was why visa was canceled
I mentioned this in the SOP
The U.S. and Canada do share immigration information. So if you went to the U.S. on a study permit and then didn't end up studying, this could certainly impact your Canadian study permit.
