After spending thousands of dollars, if this happens to anybody then its really sad. Parents and students should be aware that going abroad for studies is not what they dream of. With such a high cost of education, their young life can be hell. I truly believe, we can have quality education in less price at your own country at least in undergraduate level.
And also, I can hardly understand the stress the undergraduate students will go through during their stay away from home. They have to study, get socialize, pay for their tuition and above all will have pressure of earning money.
Please don't send teenagers to abroad study.
