Other than joke, bogus students are the main cause of all hurdles and strict procedures which are being faced by genuine students.
This is all because of people who only have an intention to make money and get settled in UK, Canada, Australia, etc.... They don't go to their classes and work 24/7 i.e. driving cabs, work on cash in factories or restaurants.
If they have not enough finances to support themselves during studies, then they should not go for this. Because in case if they complete their degrees, they will not be in the position to secure good jobs in the market because they would have not high score cards and no knowledge of subject. In the end, it will be a miserable life.
