My lawyer just had a talk with VSC. An employee on condition of anonymity admitted to this:
"We are generating RFEs/Transfers on mass scale if the work is related to telecom or information technologies like Java, databases or system admins. I transferred 5 cases all of them programmers. No bearing to nationality, 3 from India one from Gahana and one from Kenya. Just the field of work."
