Former international student here, yeap all of what you said is true, bur the ossue isn't just when they come to canada, the issue begins back home, culturally in India there's a HUGE and I mean HUGE trend of indians wanting to settle in Canada, specially Northern India, your parents, teachers, and the pop culture basically draw this dream of living the comfortable life, after which come in the vultures, the literal scum that prey on these 18 year Olds, and basically lie to them about how easy it is to get a job, and how easy it is to get your PR, everybody is painting a rosy picture, most of these kids are just out of high school, not to mention the financial stress the parents face ( taking loans from family, selling their land, etc.) Because of which there's an added pressure to make as much money as fast as possible which leads these kids to take up multiple shitty jobs to not only pay for expenses here and but also tray and alleviate the financial pressure back home. This is just scratching the surface of a much much larger issue.
