<p>We had no problem getting the permit at the Highgate border crossing in Vermont. The customs authorities were well aware of the process and it took less than 15 minutes, at most. I felt that once we had the CAQ the rest was a breeze. Just be sure to bring all the necessary paperwork ( and the fee! ).
By the way, the study permit is for three years only, although almost all US students take four years to complete McGill. So you will have to renew the permit ( and pay another fee! ) after three years.</p>
