It would be very helpful if you could provide additional information.
For the students who are already here, whose postgrad work permit may be expiring or has expired, because their work permit is not allowed to be renewed, and given their situation, they basically have no choice but to leave the country. That would mean that Canada would lose all of the talent we have with these students.
Are you aware of any students who might have had their work permits expire or whose permits are about to expire?
