For example we are from 'x' country and we are in study permit in 'y' country (like Europe/USA from south asia or africa), the work experience done during study permit in 'y' country (such as RA or teaching assistant) has not been considered in many instances.outside Canada ? Can you please explain ? As far as I know its only an issue if you are inside Canada.
But we see some getting PPR - we don't know. May be that they had score cutt-off even if removing that work experience or it may have just been slipped in ....mystery
