Well It's that time of the year when hundreds of students from India pack their bags to go and join colleges and universities in the US. And though, like previous years, there has been an increase in the number of Indians going to campuses in the US, two incidents of raids by US immigration authorities on colleges for fraudulent practices, which involved a large number of Indian students, in the past few months are causing concern.

Early this year, in January, US immigration authorities attacked Tri-Valley University in California, asserting that the school's founder and president, Susan Xiao-Ping Su, was issuing US student visas to foreign nationals willing to pay for them.

So Over 95% of Tri-Valley's 1,500 students were from India,Later, in July, the University of Northern Virginia too was attacked by the US law administration authorities on grounds of asserted visa fraud and here too, hundreds of the students were from India.
