She can complete a program of study as long as that program's total duration is six months or less.
So she can complete a certificate that takes six months or less to complete (as an example). However she cannot take separate courses that are each less than six months but add up to a certifiate / diploma / degree that is longer than six months. If she wants to do that, she needs to switch to a study permit.
I understand that if one need to pursue a program more than 6 months, study permit is required. In that case what will happen to the SOWP? Will SOWP become inactive/Void or both Study permit and SOWP will be valid and co-exist together?
If suppose, SOWP granted for 3 yers and Study permit only required for 1 year, then... Is it possible to revert back to SOWP?
